In CR4+ webex | 11:00 am | Perianne Johnson | CU Boulder | Modeling Pluto's Atmosphere and Volatile Inventory Throughout Time | |
Abstract: | In this talk, I will explore feedbacks between Pluto's surface and atmosphere over three distinct timescales. Through volatile transport, Pluto's atmosphere affects and is affected by a myriad of other systems and processes active on the dwarf planet throughout the age of the solar system. First, I model Pluto seasonal and superseasonal temperature and pressure behavior, motivated by the conundrum of Pluto's heterogeneous surface. Next, I model the formation of the Sputnik Planitia ice sheet from atmospheric condensation, and the resulting true polar wander reorientation of Pluto, which likely occurred 4 billion years ago. Finally, I model volatile loss from Pluto's early atmosphere 4.5 billion years ago, via photochemical destruction, impact erosion, and atmospheric escape. Pluto is a dynamic world, exhibiting changes over all of these timescales, and luckily, Pluto's present-day atmosphere and surface record the properties of these past-Pluto configurations. | ||||
