An estimate of the chemical composition of Titan's lakes
D. Cordier, O. Mousis, J. -I. Lunine +2
Hundreds of radar-dark patches interpreted as lakes have been discovered in the north and south polar regions of Titan. We have estimated the composition of these lakes by using th…
Elemental abundances and minimum mass of heavy elements in the envelope of HD 189733b
Olivier Mousis, Jonathan I. Lunine, Giovanna Tinetti +4
Oxygen (O) and carbon (C) have been inferred recently to be subsolar in abundance from spectra of the atmosphere of the transiting hot Jupiter HD 189733b. Yet, the mass and radius…
A primordial origin for the atmospheric methane of Saturn's moon Titan
Olivier Mousis, Jonathan I. Lunine, Matthew Pasek +5
The origin of Titan's atmospheric methane is a key issue for understanding the origin of the Saturnian satellite system. It has been proposed that serpentinization reactions in Tit…
INPOP08, a 4-D planetary ephemeris: From asteroid and time-scale computations to ESA Mars Express and Venus Express contributions
A. Fienga, J. Laskar, T. Morley +6
The latest version of the planetary ephemerides developed at the Paris Observatory and at the Besancon Observatory is presented here. INPOP08 is a 4-dimension ephemeris since it pr…
Bulk composition of the transiting hot Neptune around GJ 436
P. Figueira, F. Pont, C. Mordasini +3
The hot Neptune orbiting around GJ 436 is a unique example of an intermediate mass planet. Its close-in orbit suggests that the planet has undergone migration and its study is fund…
Extrasolar planet population synthesis II: Statistical comparison with observation
Christoph Mordasini, Yann Alibert, Willy Benz +1
This is the second paper in a series of papers showing the results of extrasolar planet population synthesis calculations. In the companion paper (Paper I), we have presented in de…
