Unfortunately, a virtual talk 🙂
Solar Contributions to Earth’s Oceans
This was a large collaborative work combining laboratory studies and analysis of grains from Itokawa. The results suggest that much of the water in Earth’s oceans could have originated from water created from solar wind implantation onto rocky airless bodies, such as asteroids.
The work has been picked up by a couple of national/local news outlets:

Presenters include faculty Christopher Edwards, Josh Emery, Mark Loeffler, Steve Tegler, Cristina Thomas, David Trilling, and Chad Trujillo; PhD students Becks Carmack, Colin Chandler, Anna Engle, Audrey Martin, Lauren McGraw, Will Oldroyd, Shae Raposa, and Patrick Tribbett; and undergraduate students Lonnie Dausend and Beau Prince; and REU student Eleanor Serviss.
There were two press releases from NAU related to this meeting: https://news.nau.edu/astronomy-dps-meeting/
Presenters include faculty Devon Burr, Christopher Edwards, and Mark Salvatore; research faculty Chris Haberle and Allie Rutledge; PhD students Helen Eifert, Natalie Jones, Ari Koeppel, Tony Maue, Christian Tai Udovicic, Aaron Weintraub, and Chris Wolfe; data scientist Nathan Smith; and former REU student Dede Chapline.
about his research on thermal oxidation reactions involving hydrogen sulfide, ozone and water. Reactions such as these are likely important in determining the composition of the surface and subsurface ice on Europa’s trailing hemisphere.
According to and informal survey of faculty and graduate students conducted by Ty Robinson: given the total number of NAU undergraduates involved in LSAMP (Louie Stokes Alliance ofr Minority Participation) in any given year, DAPS accounts for roughly 10% of all combined advising and mentoring, and about 20% of all research advising. These are strong numbers that indicate DAPS’ commitment to increasing diversity in STEM.
Cristina’s program is a three year program with a total budget around $850K. For some 20 years, researchers at MIT have run a program to obtain spectra of Near Earth Asteroids. This project became the premier telescopic program to study these bodies as they pass close to the Earth. Cristina has now taken over as PI of this long-standing program.
This is huge for Cristina and for NAU, not just for the short-term and this terrific proposal, but for the long term as well.
Congratulations, Cristina!
The PI is Joe Hora at Harvard-Smithsonian, and they will carry out one final re-analysis of Near Earth Asteroid observations made by the Spitzer Space Telescope. The total budget of the NAU portion of this project is $213K, and includes support for a PhD student for two years.

Congratulations to everyone who helped push this forward, including, in our department, Cristina Thomas.
Our department was one of the NAU sponsors for a booth at the recent SACNAS national conference.
Ryder was in Spain to observe Jupiter Trojan asteroid Polymele as it passed in front of a distant star. A few weeks later Ryder led an intrepid group of cold NAU students to watch Eurybates’ occultation — measurements that were made in the early morning from Grand Canyon National Park!
The paper is the culmination of three years of hard modeling and analysis effort, under the supervision of Phil Massey (Lowell Observatory).
A fragile record of fleeting water on Mars
Christopher Edwards and former NAU undergraduate Gabriel Carillo are co-authors on this paper.
Space weathering of the 3 micron phyllosilicate feature induced by pulsed laser irradiation.
This work is the first study to look at how the 3-micron absorption band is altered by simulated micrometeorite impacts in meteorite analogs that have undergone high degrees of aqueous alteration. This study suggests that, at least for the most aqueously altered asteroids, this spectral region may be extremely useful for determining the asteroid’s composition even if it
has been heavily processed by space weathering.
The appointment is for a nominal three year term, for the National Observatory.
In this role, and alongside other committee members, Ty will be providing guidance to NASA on issues related to all NASA planetary science programs.

The report highlighted direct imaging of potentially Earth-like exoplanets in the habitable zones of Sun-like stars as a key science goal for the coming decade(s). To support this, the Decadal recommended NASA create a new Great Observatories Mission and Technology Maturation Program, whose purpose is to develop technologies needed for pan-decadal large missions. The first mission recommended to go through this development is a ~6m ultraviolet-optical-infrared space telescope capable of characterizing exo-Earths (ie, halfway between the HabEx 4m concept and the LUVOIR-B 8m).
Ty Robinson had multiple scientific results showcased as figures in the 2020 Decadal Survey on Astronomy and Astrophysics on topics of exoplanet direct imaging and Solar System analogs for exoplanet observations. He’ll be heavily involved in this new program as the mission matures over the next decade(s).

Discovery of Super-Slow Rotating Asteroids with ATLAS and ZTF photometry
This paper includes (former) undergrad Daniel Kramer, postdoc Andrew McNeill, and David Trilling, and presents the discovery of super-slow
rotating asteroids, with periods up to 5000 hours — that’s more than200 days! This previously-unknown population was discovered through analysis of data from two long-term all-sky surveys.
It’s fun to discover a whole new class of objects that has never been seen before!
This is Will’s first first-author paper!
(Oh yeah, Will has a new baby — Claire. Congratulations on that too!)
David Trilling is PI of a 99-orbit coordinated parallel program to measure the colors of very faint objects in the distant outer Solar System. This program leverages his previously-accepted James Webb Space Telescope program to discover those objects. The two telescopes will be used simultaneously to observe these faint objects at two different wavelengths, and from two different perspectives. Professor Steve Tegler is a CoI on this proposal.
Assistant Professor Cristina Thomas is a CoI on a 19-orbit program to observe the ejecta created by the DART impact on Dimorphos.

NAU did really, really well. Three faculty were on selected proposals: David Trilling (PI of one proposal, co-PI of another); Cristina Thomas (CoI on 3 proposals); and Josh Emery (CoI on 3 proposals).
There were 22 proposals selected in the sub-area of Solar System Science, and this group of faculty are part of the proposing team for 7 of those 22 (that’s 32%).
These 22 selected proposals together represent 376 hours of telescope time, and this group of faculty are part of the proposing team for 244 of those hours (that’s 65%). Wow — NAU is part of 65% of all JWST Solar System science time allocated in Cycle 1.
Josh points out that PhD student Audrey Martin is a CoI on one of the selected proposals that he is also on, and that she contributed heavily to the proposal by writing the section dedicated to the MIRI instrument.

in Surface Science, where they used their laboratory data to show that existing models over predict the sputtering of O2 from H2O-ice by between a factor of five and eight at temperatures relevant to Europa. They were able to make an empirical correction to the existing model to match our new and other previous laboratory data. This correction should allow one to more accurately predict how efficiently exospheres can be produced by energetic ion irradiation of the surface H2O-ice on icy moons in our solar system.

PhD student Lori Pigue was named LPSC2021 Microblogger of the Day for Friday March 19:
This online workshop was held on March 23 – 26. Speakers included Josh Emery, former NAU undergrad Eric MacLennan, and PhD students Patrick Tribbett, Audrey Martin, and Annika Gustafsson. Will Grundy was a discussion moderator.
was picked up by NSF GRFP Twitter and also by the YouTube channel NWN SupremeMasterTV
After graduating from NAU, Eric obtained his PhD at the University of Tennessee in 2019, supervised by Josh Emery, and is now a Postdoctoral Fellow at the Particle Physics & Astrophysics group at the University of Helsinki, Finland.
The National Science Foundation Office of Polar Programs has recently selected a proposal led by Mark Salvatore entitled Moving Beyond the Margins: Modeling Water Availability and Habitable Terrestrial Ecosystems in the Polar Desert of the McMurdo Dry Valleys.
This collaborative project totals more than $1 million and focuses on remotely quantifying habitable environmental conditions throughout the McMurdo Dry Valleys of Antarctica using a combination of satellite imagery, high-frequency meteorological data, and ecological modeling.

NAU did really, really well. Three faculty were on selected proposals: David Trilling (PI of one proposal, co-PI of another); Cristina Thomas (CoI on 3 proposals); and Josh Emery (CoI on 3 proposals).
There were 22 proposals selected in the sub-area of Solar System Science, and this group of faculty are part of the proposing team for 7 of those 22 (that’s 32%).
These 22 selected proposals together represent 376 hours of telescope time, and this group of faculty are part of the proposing team for 244 of those hours (that’s 65%). Wow — NAU is part of 65% of all JWST Solar System science time allocated in Cycle 1.
Josh points out that PhD student Audrey Martin is a CoI on one of the selected proposals that he is also on, and that she contributed heavily to the proposal by writing the section dedicated to the MIRI instrument.
was recognized with one of this year’s President’s Achievement Awards.
Congratulations, Kerry!
The award comes with $150k to help Tyler explore the impacts of precursors masses on exoplanet atmospheric characterization while also studying the role of interdisciplinarity in undergraduate education and building a diversity-focused undergraduate research mentorship program in DAPS.
This is only the second Cottrell Fellowship to ever be awarded to NAU (the first being to John Gibbs!), and details can be found here:
Congratulations, Dom!

Ahmed is from the UAE and spent two summers working at NAU alongside our REU program, as part of a program led by Christopher Edwards to train Emirati undergraduate students in planetary science research. Ahmed is the lead author of this paper. He participated remotely in our summer research program in summer, 2020 — an 11 hour time difference!
in Surface Science, where they used their laboratory data to show that existing models over predict the sputtering of O2 from H2O-ice by between a factor of five and eight at temperatures relevant to Europa. They were able to make an empirical correction to the existing model to match our new and other previous laboratory data. This correction should allow one to more accurately predict how efficiently exospheres can be produced by energetic ion irradiation of the surface H2O-ice on icy moons in our solar system.
