HD219666b: A hot-Neptune from TESS Sector 1
M. Esposito, D. J. Armstrong, D. Gandolfi +73
We report on the confirmation and mass determination of a transiting planet orbiting the old and inactive G7 dwarf star HD219666 (Mstar = 0.92 +/- 0.03 MSun, Rstar = 1.03 +/- 0.03…
A 4.6-year period brown-dwarf companion interacting with the hot-Jupiter CoRoT-20 b
J. Rey, F. Bouchy, M. Stalport +18
We report the discovery of an additional substellar companion in the CoRoT-20 system based on six years of HARPS and SOPHIE radial velocity follow-up. CoRoT-20 c has a minimum mass…
Radial velocity follow-up of GJ1132 with HARPS. A precise mass for planet 'b' and the discovery of a second planet
X. Bonfils, J. -M. Almenara, R. Cloutier +19
GJ1132 is a nearby red dwarf known to host a transiting Earth-size planet. After its initial detection, we pursued an intense follow-up with the HARPS velocimeter. We now confirm t…
Quantifying the Bayesian Evidence for a Planet in Radial Velocity Data
Benjamin E. Nelson, Eric B. Ford, Johannes Buchner +5
We present results from a data challenge posed to the radial velocity (RV) community: namely, to quantify the Bayesian "evidence" for n={0,1,2,3} planets in a set of synthetically…
Absolute densities in exoplanetary systems: photodynamical modelling of Kepler-138
J. M. Almenara, R. F. Díaz, C. Dorn +2
In favourable conditions, the density of transiting planets in multiple systems can be determined from photometry data alone. Dynamical information can be extracted from light curv…
