A Multiple Scattering Polarized Radiative Transfer Model: Application to HD 189733b
Pushkar Kopparla, Vijay Natraj, Xi Zhang +3
We present a multiple scattering vector radiative transfer model which produces disk integrated, full phase polarized light curves for reflected light from an exoplanetary atmosphe…
Tracing the fate of carbon and the atmospheric evolution of Mars
Renyu Hu, David M. Kass, Bethany L. Ehlmann +1
The climate of Mars likely evolved from a warmer, wetter early state to the cold, arid current state. However, no solutions for this evolution have previously been found to satisfy…
Reflected Light Curves, Spherical and Bond Albedos of Jupiter- and Saturn-like Exoplanets
Ulyana Dyudina, Xi Zhang, Liming Li +5
Reflected light curves observed for exoplanets indicate bright clouds at some of them. We estimate how the light curve and total stellar heating of a planet depend on forward and b…
A Ground-Based Albedo Upper Limit for HD 189733b from Polarimetry
Sloane J. Wiktorowicz, Larissa A. Nofi, Daniel Jontof-Hutter +5
We present 50 nights of polarimetric observations of HD 189733 in band using the POLISH2 aperture-integrated polarimeter at the Lick Observatory Shane 3-m telescope. This instr…
Helium Atmospheres on Warm Neptune- and Sub-Neptune-Sized Exoplanets and Applications to GJ 436 b
Renyu Hu, Sara Seager, Yuk L. Yung
Warm Neptune- and sub-Neptune-sized exoplanets in orbits smaller than Mercury's are thought to have experienced extensive atmospheric evolution. Here we propose that a potential ou…
Stability of CO2 Atmospheres on Desiccated M Dwarf Exoplanets
Peter Gao, Renyu Hu, Tyler D. Robinson +2
We investigate the chemical stability of CO2-dominated atmospheres of desiccated M dwarf terrestrial exoplanets using a 1-dimensional photochemical model. Around Sun-like stars, CO…
