Venus as an Exoplanet: I. An Initial Exploration of the 3-D Energy Balance for a CO Exoplanetary Atmosphere Around an M-Dwarf Star

Christopher D. Parkinson, Stephen W. Bougher, Franklin P. Mills +5

The chemical evolution of an exoplanetary Venus-like atmosphere is dependent upon the ultraviolet to near ultraviolet (FUV-NUV) radiation ratio from the parent star, the balance be…

Atmospheric Escape Processes and Planetary Atmospheric Evolution

Guillaume Gronoff, Phil Arras, Suleiman M Baraka +17

The habitability of the surface of any planet is determined by a complex evolution of its interior, surface, and atmosphere. The electromagnetic and particle radiation of stars dri…

Solar System Ice Giants: Exoplanets in our Backyard

Abigail Rymer, Kathleen Mandt, Dana Hurley +110

Future remote sensing of exoplanets will be enhanced by a thorough investigation of our solar system Ice Giants (Neptune-size planets). What can the configuration of the magnetic f…

On the Insignificance of Photochemical Hydrocarbon Aerosols in the Atmospheres of Close-in Extrasolar Giant Planets

Mao-Chang Liang, Sara Seager, Christopher D. Parkinson +3

The close-in extrasolar giant planets (CEGPs) reside in irradiated environments much more intense than that of the giant planets in our solar system. The high UV irradiance strongl…

Detection of oxygen and carbon in the hydrodynamically escaping atmosphere of the extrasolar planet HD209458b

A. Vidal-Madjar, J. -M. Désert, A. Lecavelier des Etangs +7

Four transits of the planet orbiting the star HD209458 were observed with the STIS spectrograph on board HST. The wavelength domain (1180-1710A) includes HI as well as CI, CII, CIV…
