SOPHIE and TESS characterization of fourteen TESS Objects of Interest: nine planetary systems and five low-mass stellar companions
N. Heidari, G. Hébrard, S. Sousa +61
We present fourteen TESS Objects of Interest (TOIs) from the SOPHIE-TESS follow-up program. Combining TESS photometry, SOPHIE radial velocities (RVs), ground-based photometry, and…
Upper limits on CN from exocomets transiting Pictoris
M. A. Kenworthy, E. de Mooij, A. Brandeker +3
The young (23 Myr) nearby (19.4 pc) star Pictoris hosts an edge-on debris disk with two gas giant exoplanets in orbit around it. Many transient absorption features have been de…
A Swarm of WASP Planets: Nine giant planets identified by the WASP survey
Nicole Schanche, Guillaume Hébrard, Keivan G. Stassun +52
The Wide Angle Search for Planets (WASP) survey provided some of the first transiting hot Jupiter candidates. With the addition of the Transiting Exoplanet Survey Satellite (TESS),…
Abundances of refractory ions in Beta Pictoris exocomets
T. Vrignaud, A. Lecavelier des Etangs, P. A. Strom +1
Beta Pic is a young, A5V star, known for harbouring a large number of exocomets, which frequently transit the star and produce absorption signatures. The physical and chemical prop…
Characterization of seven transiting systems including four warm Jupiters from SOPHIE and TESS
N. Heidari, G. H'ebrard, E. Martioli +65
We present the study of seven systems, three of which TOI-2295, TOI-2537, and TOI-5110 are newly discovered planetary systems. Through the analysis of TESS photometry, SOPHIE radia…
Giant planets population around B stars from the first part of the BEAST survey
P. Delorme, A. Chomez, V. Squicciarini +23
Exoplanets form from circumstellar protoplanetary discs whose fundamental properties (notably their extent, composition, mass, temperature and lifetime) depend on the host star pro…
TOI-3568 b: a super-Neptune in the sub-Jovian desert
E. Martioli, R. P. Petrucci, E. Jofre +42
The sub-Jovian desert is a region in the mass-period and radius-period parameter space, typically encompassing short-period ranges between super-Earths and hot Jupiters, that exhib…
TOI-1199 b and TOI-1273 b: Two new transiting hot Saturns detected and characterized with SOPHIE and TESS
J. Serrano Bell, R. F. Díaz, G. Hébrard +41
We report the characterization of two planet candidates detected by the Transiting Exoplanet Survey Satellite (TESS), TOI-1199 b and TOI-1273 b, with periods of 3.7 and 4.6 days, r…
Curves of growth for transiting exocomets: Application to Fe II lines in the Beta Pictoris system
T. Vrignaud, A. Lecavelier des Etangs, F. Kiefer +4
This study introduces the exocomet curve of growth, a new method to analyse the variable absorptions observed in Pictoris spectrum and link them to the physical properties of t…
A new treatment of telluric and stellar features for medium resolution spectroscopy and molecular mapping. Application to the abundance determination on Beta Pic b
F. Kiefer, M. Bonnefoy, B. Charnay +5
Molecular mapping is a supervised method exploiting the spectral diversity of integral field spectrographs to detect and characterize resolved exoplanets blurred into the stellar h…
The EBLM Project XI. Mass, radius and effective temperature measurements for 23 M-dwarf companions to solar-type stars observed with CHEOPS
M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +104
Observations of low-mass stars have frequently shown a disagreement between observed stellar radii and radii predicted by theoretical stellar structure models. This ``radius inflat…
Fe I in the β Pictoris circumstellar gas disk I. Physical properties of the neutral iron gas
A. Vidal-Madjar, F. Kiefer, A. Lecavelier des Etangs +5
The young planetary system β Pictoris is surrounded by a circumstellar disk of dust and gas. Because both dust and gas have a lifetime shorter than the system age, they need to be…
