An M dwarf star in the transition disk of Herbig HD142527; Physical parameters and orbital elements
... This dataset covers two years of observations, but only a small arc of the orbit is observed, corresponding to 15 degrees in position angle. The first approximation is therefore to con- sider that our knowledge is ...

(1173) Anchises - thermophysical and dynamical studies of a dynamically unstable Jovian Trojan
... Unlike the aforementioned Neptunian Trojans, the dynamical stability of Anchises was not found to vary as a function of the object’s initial orbital elements. This is almost certainly the result of the ...

New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems
... We presented a sample of 24 giant stars that have revealed large radial velocity variations, which are induced by massive sub- stellar or stellar companions. Based on precision RVs computed from high-resolution ...
