Science goals and new mission concepts for future exploration of Titan's atmosphere geology and habitability: Titan POlar Scout/orbitEr and In situ lake lander and DrONe explorer (POSEIDON)

Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +61

In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn largest m…

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…

Pluto's atmosphere observations with ALMA: spatially-resolved maps of CO and HCN emission and first detection of HNC

E. Lellouch, B. Butler, R. Moreno +6

Following the detection of CO and HCN in Pluto's atmosphere, we report on new ALMA observations of Pluto with two main goals: (i) obtaining spatially-resolved measurements (~0.06''…

The near-UV transit of HD 189733b with the XMM-Newton Optical Monitor

George W. King, Lía Corrales, Peter J. Wheatley +6

We present analysis of XMM-Newton Optical Monitor observations in the near-ultraviolet of HD 189733, covering twenty primary transits of its hot Jupiter planet. The transit is clea…

HST PanCET program: Non-detection of atmospheric escape in the warm Saturn-sized planet WASP-29 b

L. A. dos Santos, V. Bourrier, D. Ehrenreich +10

(Abridged) Short-period gas giant exoplanets are susceptible to intense atmospheric escape due to their large scale heights and strong high-energy irradiation. This process is thou…

The Hubble PanCET program: Long-term chromospheric evolution and flaring activity of the M dwarf host GJ 3470

V. Bourrier, L. A. dos Santos, J. Sanz-Forcada +9

Neptune-size exoplanets seem particularly sensitive to atmospheric evaporation, making it essential to characterize the stellar high-energy radiation that drives this mechanism. Th…

Impact of photochemical hazes and gases on exoplanet atmospheric thermal structure

Panayotis Lavvas, Anthony Arfaux

We investigate the impact of photochemical hazes and disequilibrium gases on the thermal structure of hot-Jupiters, using a detailed 1-D radiative-convective model. We find that th…
