Context. Recent discoveries of new trans-Neptunian objects have greatly increased the attention by the scientific community to this relatively unknown region of the solar system. The current level of precision achieved in the description of planet orbits has transformed modern ephemerides in the most updated tools for studying the gravitational in…

We present a study of the seasonal evolution of Titan's thermal field and distributions of haze, C2H2, C2H4, C2H6, CH3C2H, C3H8, C4H2, C6H6, HCN, and HC3N from March 2015 (Ls

Understanding Saturn's interior from the Cassini Grand Finale gravity measurements
DOI: 10.1051/0004-6361/202038267 Bibcode: 2020A&A...639A..10N

Ni, Dongdong

Context. Measurements of Saturn's gravity field by Cassini Grand Finale have been acquired with high precision. It has been demonstrated that the even gravitational harmonics J6-J10 have larger absolute values than the predictions by typical rigid-body interior models. A four-layer structure model, proposed to interpret Juno'…

The chemical composition of impact craters on Titan. I. Implications for exogenic processing
DOI: 10.1051/0004-6361/202037866 Bibcode: 2020A&A...641A..16S

Drossart, P.; Witasse, O.; Altobelli, N. +12 more

We investigate the spectral behavior of nine Titan impact craters in order to constrain their composition. Past studies that have examined the chemical composition of impact craters on Titan have either used qualitative comparisons between craters or combined all craters into a single unit, rather than separating them by geographic location and/or…
