The SPHERE infrared survey for exoplanets (SHINE) V. Full sample characterization
V. Squicciarini, S. Desidera, G. Chauvin +109
Unbiased surveys of large stellar samples are the prime means through which the prevalence of exoplanets can be derived, and crucial constraints to planet formation models can be s…
Radial velocity homogeneous analysis of M dwarfs observed with HARPS. II. Detection limits and planetary occurrence statistics
L. Mignon, X. Delfosse, N. Meunier +13
We re-determine planetary occurrences around M dwarfs using 20 years of observations from HARPS on 197 targets. The first aim of this study is to propose more precise occurrence ra…
Radial velocity homogeneous analysis of M dwarfs observed with HARPS I. Exoplanet detection and candidates
L. Mignon X. Delfosse, X. Bonfils, N. Meunier +11
The census of planets around M dwarfs in the solar neighbourhood meets two challenges: detecting the best targets for the future characterisation of planets with ELTs, and studying…
The SPHERE infrared survey for exoplanets (SHINE). V. Complete observations, data reduction and analysis, detection performances, and final results
A. Chomez, P. Delorme, A. -M. Lagrange +117
During the past decade, state-of-the-art planet-finder instruments like SPHERE@VLT, coupling coronagraphic devices and extreme adaptive optics systems, unveiled, thanks to large su…
Searching for substellar companion candidates with Gaia. III. Search for companions to members of young associations
A. -M. Lagrange, F. Kiefer, P. Rubini +13
Absolute astrometry with Gaia is expected to detect and characterize the orbits of thousands of exoplanets in the coming years. A tool, GaiaPMEX, was recently developed to characte…
A low-mass sub-Neptune planet transiting the bright active star HD 73344
S. Sulis, I. J. M. Crossfield, A. Santerne +33
Context. Planets with radii of between 2-4 RE closely orbiting solar-type stars are of significant importance for studying the transition from rocky to giant planets. Aims. Our goa…
A new estimation of astrometric exoplanet detection limits in the habitable zone around nearby stars
Nadège Meunier, Anne-Marie Lagrange
Astrometry is less sensitive to stellar activity than the radial velocity technique when attempting to detect Earth mass planets in the habitable zone of solar-type stars. This is…
The SPHERE infrared survey for exoplanets (SHINE) -- II. Observations, Data reduction and analysis Detection performances and early-results
M. Langlois, R. Gratton, A. -M. Lagrange +118
Over the past decades, direct imaging has confirmed the existence of substellar companions (exoplanets or brown dwarfs) on wide orbits (>10 au) from their host stars. To understand…
VLT/SPHERE exploration of the young multiplanetary system PDS70
D. Mesa, M. Keppler, F. Cantalloube +51
Context. PDS 70 is a young (5.4 Myr), nearby (~113 pc) star hosting a known transition disk with a large gap. Recent observations with SPHERE and NACO in the near-infrared (NIR) al…
Constraints on HD113337 fundamental parameters and planetary system. Combining long-base visible interferometry, disk imaging and high-contrast imaging
S. Borgniet, K. Perraut, K. Su +13
HD113337 is a Main-Sequence F6V field star more massive than the Sun, hosting one (possibly two) radial velocity (RV) giant planet(s) and a cold debris disk (marked by an infrared…
Extrasolar planets and brown dwarfs around AF-type stars. IX. The HARPS southern sample
Simon Borgniet, Anne-Marie Lagrange, Nadège Meunier +1
Massive, Main-Sequence AF-type stars have so far remained unexplored in past radial velocity surveys, due to their small number of spectral lines and their high rotational velociti…
