Mercury's Crustal Magnetization Indicates a Stronger Ancient Dynamo

Isaac S. Narrett, Benjamin P. Weiss, Sarah C. Steele +1

Mercury is the only terrestrial planet in the solar system other than Earth with an active dynamo magnetic field (~200 nT at the equatorial surface). Furthermore, Mercury's ~3.9-3.…

A Radially Resolved Magnetic Field Threading the Disk of TW Hya

Richard Teague, Boy Lankhaar, Sean M. Andrews +5

We present a new approach to detecting and characterizing a magnetic field in protoplanetary disks through the differential broadening of unpolarized molecular emission from CN. To…

Can metal-rich worlds form by giant impacts?

Saverio Cambioni, Benjamin P. Weiss, Erik Asphaug +5

Planets and stars are expected to be compositionally linked because they accrete from the same material reservoir. However, astronomical observations revealed the existence of exop…

Magnetic Field Draping in Induced Magnetospheres: Evidence from the MAVEN Mission to Mars

A. R. Azari, E. Abrahams, F. Sapienza +8

The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission has been orbiting Mars since 2014 and now has over 10,000 orbits which we use to characterize Mars' dynamic space environ…

Revealing the interior structure of icy moons with a Bayesian approach to magnetic induction measurements

John B. Biersteker, Benjamin P. Weiss, Corey J. Cochrane +6

Some icy moons and small bodies in the solar system are believed to host subsurface liquid water oceans. The interaction of these saline, electrically conductive oceans with time-v…

Integrating Machine Learning for Planetary Science: Perspectives for the Next Decade

Abigail R. Azari, John B. Biersteker, Ryan M. Dewey +13

Machine learning (ML) methods can expand our ability to construct, and draw insight from large datasets. Despite the increasing volume of planetary observations, our field has seen…

Losing Oceans: The Effects of Composition on the Thermal Component of Impact-driven Atmospheric Loss

John B. Biersteker, Hilke E. Schlichting

The formation of the solar system's terrestrial planets concluded with a period of giant impacts. Previous works examining the volatile loss caused by the impact shock in the moon-…

Atmospheric mass loss due to giant impacts: the importance of the thermal component for hydrogen-helium envelopes

John B. Biersteker, Hilke E. Schlichting

Systems of close-in super-Earths display striking diversity in planetary bulk density and composition. Giant impacts are expected to play a role in the formation of many of these w…

Determining Exoplanetary Oblateness Using Transit Depth Variations

John B. Biersteker, Hilke Schlichting

The measurement of an exoplanet's oblateness and obliquity provides insights into the planet's internal structure and formation history. Previous work using small differences in th…

Arcsecond resolution mapping of Sulfur Dioxide emission in the circumstellar envelope of VY Canis Majoris

Roger Fu, Arielle Moullet, Nimesh A. Patel +3

We report Submillimeter Array observations of SO2 emission in the circumstellar envelope of the red supergiant VY CMa, with an angular resolution of ~1". SO2 emission appears in th…
