Extrasolar planets and brown dwarfs around AF-type stars. X.The SOPHIE northern sample. Combining the SOPHIE and HARPS surveys to compute the close giant planet mass-period distribution around AF-type stars
S. Borgniet, A. -M. Lagrange, N. Meunier +31
The impact of the stellar mass on the giant planet properties is still to be fully understood. Main-Sequence (MS) stars more massive than the Sun remain relatively unexplored in ra…
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…
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…
K-Stacker: Keplerian image recombination for the direct detection of exoplanets
M. Nowak, H. Le Coroller, L. Arnold +5
We present a proof of concept for a new algorithm which can be used to detect exoplanets in high contrast images. The algorithm properly combines mutliple observations acquired dur…
Overview of the DESI Legacy Imaging Surveys
Arjun Dey, David J. Schlegel, Dustin Lang +157
The DESI Legacy Imaging Surveys are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Surve…
