Inferring heat recirculation and albedo for exoplanetary atmospheres: Comparing optical phase curves and secondary eclipse data
P. von Paris, P. Gratier, P. Bordé +1
Basic atmospheric properties such as albedo and heat redistribution between day and nightside have been inferred for a number of planets using observations of secondary eclipses an…
2D photochemical modeling of Saturn's stratosphere. Part II: Feedback between composition and temperature
V. Hue, T. K. Greathouse, T. Cavalié +2
Saturn's axial tilt produces seasons in a similar way as on Earth. Both the stratospheric temperature and composition are affected by this latitudinally varying insolation along th…
Ethyl alcohol and sugar in comet C/2014Q2 (Lovejoy)
Nicolas Biver, Dominique Bockelée-Morvan, Raphaël Moreno +7
The presence of numerous complex organic molecules (COMs; defined as those containing six or more atoms) around protostars shows that star formation is accompanied by an increase o…
Radar scattering of linear dunes and mega-yardangs: Application to Titan
Philippe Paillou, Benoît Seignovert, Jani Radebaugh +1
The Ku-band (13.8 GHz - 2.2 cm) RADAR instrument onboard the Cassini-Huygens spacecraft has revealed the richness of the surface of Titan, as numerous seas, lakes, rivers, cryo-vol…
Fast migration of low-mass planets in radiative discs
Arnaud Pierens
Low-mass planets are known to undergo Type I migration and this process must have played a key role during the evolution of planetary systems. Analytical formulae for the disc torq…
Terrestrial Planet Formation Constrained by Mars and the Structure of the Asteroid Belt
André Izidoro, Sean N. Raymond, Alessandro Morbidelli +1
Reproducing the large Earth/Mars mass ratio requires a strong mass depletion in solids within the protoplanetary disk between 1 and 3 AU. The Grand Tack model invokes a specific mi…
