Towards a coupled activity-fallback model for comets I) 67P/Churyumov-Gerasimenko's water activity from a microphysics model with dynamic dust-depth
Nicholas Attree, Yuri Skorov, Pedro Gutiérrez +4
We apply a two-layer thermophysical model, with water sublimating from below a dust-crust with dynamically varying depth, to simulate the water outgassing rate, dust-ejections, and…
Terrestrial Analogs to Titan for Geophysical Research
Conor A. Nixon, Samuel Birch, Audrey Chatain +19
Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These includ…
Retention of CO Ice and Gas Within 486958 Arrokoth
Samuel P. D. Birch, Orkan M. Umurhan
Kuiper Belt Objects (KBOs) represent some of the most ancient remnants of our solar system, having evaded significant thermal or evolutionary processing. This makes them important…
Airfall on Comet 67P/Churyumov-Gerasimenko
B. J. R. Davidsson, S. Birch, G. A. Blake +11
We here study the transfer process of material from one hemisphere to the other (deposition of airfall material) on an active comet nucleus, specifically 67P/Churyumov-Gerasimenko.…
A Near Surface Temperature Model of Arrokoth
O. M. Umurhan, W. M. Grundy, M. K. Bird +19
A near surface thermal model for Arrokoth is developed based on the recently released facet model of the body. This thermal solution takes into account Arrokoth's surface re…
Hypotheses for Triton's Plumes: New Analyses and Future Remote Sensing Tests
Jason D. Hofgartner, Samuel P. D. Birch, Julie Castillo +14
At least two active plumes were observed on Neptune's moon Triton during the Voyager 2 flyby in 1989. Models for Triton's plumes have previously been grouped into five hypotheses,…
