The high-albedo, low polarization disk around HD 114082 harbouring a Jupiter-sized transiting planet
N. Engler, J. Milli, R. Gratton +36
We present new optical and near-IR images of debris disk around the F-type star HD 114082. We obtained direct imaging observations and analysed the TESS photometric time series dat…
A HARPS radial velocity search for planets in the Scorpius-Centaurus association. And its combination with the HARPS and SOPHIE young nearby stars (YNS) surveys
Antoine Grandjean, A. -M. Lagrange, N. Meunier +13
The Scorpius-Centaurus (Sco-Cen) young and nearby massive star-forming region is particularly well suited for extrasolar planet searches with both direct imaging and radial velocit…
Direct discovery of the inner exoplanet in the HD206893 system. Evidence for deuterium burning in a planetary-mass companion
S. Hinkley, S. Lacour, G. -D. Marleau +110
Long term precise radial velocity (RV) monitoring of the nearby star HD206893, as well as anomalies in the system proper motion, have suggested the presence of an additional, inner…
One year of AU Mic with HARPS: I -- measuring the masses of the two transiting planets
Norbert Zicher, Oscar Barragán, Baptiste Klein +11
The system of two transiting Neptune-sized planets around the bright, young M-dwarf AU Mic provides a unique opportunity to test models of planet formation, early evolution, and st…
Dynamical masses for two M1 + mid-M dwarf binaries monitored during the SPHERE-SHINE survey
Beth A. Biller, Antoine Grandjean, Sergio Messina +25
We present orbital fits and dynamical masses for HIP 113201AB and HIP 36985AB, two M1 + mid-M dwarf binary systems monitored as part of the SPHERE SHINE survey. To robustly determi…
A SOPHIE RV search for giant planets around young nearby stars (YNS). A combination with the HARPS YNS survey
A. Grandjean, A. -M. Lagrange, N. Meunier +9
The search of close (a<=5 au) giant planet(GP) companions with radial velocity(RV) around young stars and the estimate of their occurrence rates is important to constrain the migra…
New binaries from the SHINE survey
M. Bonavita, R. Gratton, S. Desidera +67
We present the multiple stellar systems observed within the SpHere INfrared survey for Exoplanet (SHINE). SHINE searched for substellar companions to young stars using high contras…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) VI. Non-detection of sodium with HARPS on the bloated super-Neptune WASP-127b
J. V. Seidel, M. Lendl, V. Bourrier +17
WASP-127b is one of the puffiest exoplanets found to date, with a mass only Neptune masses, but a radius larger than Jupiter. It is also located at the border of the Neptune…
Direct confirmation of the radial-velocity planet Pic c
M. Nowak, S. Lacour, A. -M. Lagrange +90
Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…
A HARPS RV search for planets around young nearby stars
A. Grandjean, A. -M. Lagrange, M. Keppler +9
Young nearby stars are good candidates in the search for planets with both radial velocity (RV) and direct imaging techniques. This, in turn, allows for the computation of the gian…
Constraining the properties of HD 206893 B. A combination of radial velocity, direct imaging, and astrometry data
A. Grandjean, A. -M. Lagrange, H. Beust +25
High contrast imaging enables the determination of orbital parameters for substellar companions (planets, brown dwarfs) from the observed relative astrometry and the estimation of…
The SPHERE view of the jet and the envelope of RY Tau
A. Garufi, L. Podio, F. Bacciotti +40
Jets are rarely associated with pre-main-sequence intermediate-mass stars. Optical and near-IR observations of jet-driving sources are often hindered by the presence of a natal env…
Dynamical masses of M-dwarf binaries in young moving groups: I - The case of TWA 22 and GJ 2060
L. Rodet, M. Bonnefoy, S. Durkan +48
Evolutionary models are widely used to infer the mass of stars, brown dwarfs, and giant planets. Their predictions are thought to be less reliable at young ages ( 200 Myr) and i…
