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…
Measuring precise radial velocities and cross-correlation function line-profile variations using a Skew Normal density
Umberto Simola, Xavier Dumusque, Jessi Cisewski-Kehe
Stellar activity is one of the primary limitations to the detection of low-mass exoplanets using the radial-velocity (RV) technique. We propose to estimate the variations in shape…
Measuring precise radial velocities on individual spectral lines. I. Validation of the method and application to mitigate stellar activity
Xavier Dumusque
Stellar activity is the main limitation to the detection of Earth-twins using the RV technique. Despite many efforts in trying to mitigate the effect of stellar activity using empi…
K2-265 b: A Transiting Rocky Super-Earth
K. W. F. Lam, A. Santerne, S. G. Sousa +34
We report the discovery of the super-Earth K2-265 b detected with K2 photometry. The planet orbits a bright (V_mag = 11.1) star of spectral type G8V with a period of 2.37 days. We…
The 55 Cnc system reassessed
V. Bourrier, X. Dumusque, C. Dorn +9
Orbiting a bright, nearby star the 55 Cnc system offers a rare opportunity to study a multiplanet system that has a wide range of planetary masses and orbital distances. Using two…
The SOPHIE search for northern extrasolar planets XIII. Two planets around M-dwarfs Gl617A and Gl96
M. J. Hobson, R. F. Díaz, X. Delfosse +32
We report the detection of two exoplanets and a further tentative candidate around the M-dwarf stars Gl96 and Gl617A, based on radial velocity measurements obtained with the SOPHIE…
