A giant comet-like cloud of hydrogen escaping the warm Neptune-mass exoplanet GJ 436b [PDF]
Nature, 2015 Exoplanets orbiting close to their parent stars could lose some fraction of their atmospheres because of the extreme irradiation. Atmospheric mass loss primarily affects low-mass exoplanets, leading to suggest that hot rocky planets might have begun as ...

NIMBUS: The Near-Infrared Multi-Band Ultraprecise Spectroimager for SOFIA [PDF]
, 2012 We present a new and innovative near-infrared multi-band ultraprecise spectroimager (NIMBUS) for SOFIA. This design is capable of characterizing a large sample of extrasolar planet atmospheres by measuring elemental and molecular abundances during ...

The Ultraviolet Radiation Environment Around M dwarf Exoplanet Host Stars [PDF]
, 2012 The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. At present, little observational or theoretical basis exists for understanding the ultraviolet spectra of M ...

Magnetohydrodynamical Torsional Oscillations from Thermoresistive Instability in Hot Jupiters
The Astrophysical Journal, 2023 Hot Jupiter atmospheres may be subject to a thermoresistive instability where an increase in the electrical conductivity due to ohmic heating results in runaway of the atmospheric temperature.
