Detectability of shape deformation in short-period exoplanets
B. Akinsanmi, S. C. C. Barros, N. C. Santos +4
Short-period planets suffer from extreme tidal forces from their parent stars causing them to deform and attain non-spherical shapes. The planet shapes, modeled here as triaxial el…

D. Barbato, A. Sozzetti, K. Biazzo +40
Statistical studies of exoplanets have shown that giant planets are more commonly hosted by metal-rich dwarf stars than low-metallicity ones, while such a correlation is not eviden…
Machine-learning Approaches to Exoplanet Transit Detection and Candidate Validation in Wide-field Ground-based Surveys
N. Schanche, A. Collier Cameron, G. Hébrard +23
Since the start of the Wide Angle Search for Planets (WASP) program, more than 160 transiting exoplanets have been discovered in the WASP data. In the past, possible transit-like e…
Predicted Yield of Transits of Known Radial Velocity Exoplanets from the TESS Primary and Extended Missions
Paul A. Dalba, Stephen R. Kane, Thomas Barclay +5
Radial velocity (RV) surveys have detected hundreds of exoplanets through their gravitational interactions with their host stars. Some will be transiting, but most lack sufficient…
K2 Targets Observed with SPHERE/VLT: An M4-7 Dwarf Companion Resolved around EPIC 206011496
Roxanne Ligi, Olivier Demangeon, Susana Barros +6
The quest to discover exoplanets is one of the most important missions in astrophysics, and is widely performed using the transit method, which allows for the detection of exoplane…
SWEET-Cat updated. New homogenous spectroscopic parameters

Context: Exoplanets have now been proven to be very common. The number of its detections continues to grow following the development of better instruments and missions. One key ste…
Confirmation of the radial velocity super-Earth K2-18c with HARPS and CARMENES
R. Cloutier, N. Astudillo-Defru, R. Doyon +13
In an earlier campaign to characterize the mass of the transiting temperate super-Earth K2-18b with HARPS, a second, non-transiting planet was posited to exist in the system at $\s…
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…
K2-263b: A 50-day period sub-Neptune with a mass measurement using HARPS-N
A. Mortier, A. S. Bonomo, V. M. Rajpaul +32
This paper reports on the validation and mass measurement of K2-263b, a sub-Neptune orbiting a quiet G9V star. Using K2 data from campaigns C5 and C16, we find this planet to have…

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…
Activity induced variation in spin-orbit angles as derived from Rossiter-McLaughlin measurements
M. Oshagh, A. H. M. J. Triaud, A. Burdanov +17
One of the most powerful methods used to estimate sky-projected spin-orbit angles of exoplanetary systems is through a spectroscopic transit observation known as the Rossiter-McLau…
