Saturn's atmospheric response to the large influx of ring material inferred from Cassini INMS measurements

Julianne I. Moses, Zarah L. Brown, Tommi T. Koskinen +12

During the Grand Finale stage of the Cassini mission, organic-rich ring material was discovered to be flowing into Saturn's equatorial upper atmosphere at a surprisingly large rate…

The Demographics of Kepler's Earths and super-Earths into the Habitable Zone

Galen J. Bergsten, Ilaria Pascucci, Gijs D. Mulders +2

Understanding the occurrence of Earth-sized planets in the habitable zone of Sun-like stars is essential to the search for Earth analogues. Yet a lack of reliable Kepler detections…

Mass loss by atmospheric escape from extremely close-in planets

Tommi Koskinen, Panayotis Lavvas, Chenliang Huang +3

We explore atmospheric escape from close-in exoplanets with the highest mass loss rates. First, we locate the transition from stellar X-ray and UV-driven escape to rapid Roche lobe…

Energy deposition in Saturn's equatorial upper atmosphere

J. M. Chadney, T. T. Koskinen, X. Hu +6

We construct Saturn equatorial neutral temperature and density profiles of H, H, He, and CH, between 10 and 1 bar using measurements from Cassini's Ion Neutral Mass…

Non-local thermodynamic equilibrium effects determine the upper atmospheric temperature structure of the ultra-hot Jupiter KELT-9b

L. Fossati, M. E. Young, D. Shulyak +5

Several results indicate that the atmospheric temperature of the ultra-hot Jupiter KELT-9b in the main line formation region is a few thousand degrees higher than predicted by self…

A pole to pole pressure temperature map of Saturn's thermosphere from Cassini Grand Finale data

Zarah Brown, Tommi Koskinen, Ingo Mueller-Wodarg +3

Temperatures of the outer planet thermospheres exceed those predicted by solar heating alone by several hundred degrees. Enough energy is deposited at auroral regions to heat the e…
