Radial velocity detection of the TRAPPIST-1 planetary system with SPIRou and NIRPS
Alexandrine L'Heureux, René Doyon, Charles Cadieux +57
The TRAPPIST-1 system is well-known for its seven transiting Earth-sized exoplanets. It has been extensively studied and characterized, notably with transit timing variations (TTVs…
BEBOP VIII. SOPHIE radial velocities reveal an eccentric, circumbinary brown dwarf
Amaury H. M. J. Triaud, Thomas A. Baycroft, Neda Heidari +18
Circumbinary configurations offer a test of planet formation in an altered environment, where the inner binary has perturbed a protoplanetary disc. Comparisons of the physical and…
Search for exocomets transits in Kepler light curves: Ten new transits identified
Pierre Dumond, Alain Lecavelier des Etangs, Flavien Kiefer +2
The Kepler mission, despite its conclusion over a decade ago, continues to offer a rich dataset for uncovering new astrophysical objects and phenomena. In this study, we conducted…
Chromaticity of stellar activity in radial velocities : Anti-correlated families of lines on the M dwarf EV Lac with SPIRou and SOPHIE
Pierre Larue, Xavier Delfosse, Andres Carmona +33
Context. In the search for exoplanets using radial velocities (RV), stellar activity has become one of the main limiting factors for detectability. Fortunately, activity-induced RV…
BEBOP VII. SOPHIE discovery of BEBOP-3b, a circumbinary giant planet on an eccentric orbit
Thomas A. Baycroft, Alexandre Santerne, Amaury H. M. J. Triaud +21
Planetary systems orbiting close binaries are valuable testing grounds for planet formation and migration models. More detections with good mass measurements are needed. We present…
SPIRou: a spectropolarimeter for the CFHT
C. Moutou, I. Boisse, G. Hebrard +4
SPIRou is a near-infrared spectropolarimeter and high-precision radial-velocity instrument, to be mounted on the 3.6m Canada-France-Hawaii telescope ontop Maunakea and to be offere…
CoRoT-22 b: a validated 4.9 RE exoplanet in 10-day orbit
C. Moutou, J-M. Almenara, R. F. Diaz +36
The CoRoT satellite has provided high-precision photometric light curves for more than 163,000 stars and found several hundreds of transiting systems compatible with a planetary sc…
World-leading science with SPIRou - the nIR spectropolarimeter / high-precision velocimeter for CFHT
X. Delfosse, J. -F. Donati, D. Kouach +22
SPIRou is a near-infrared (nIR) spectropolarimeter / velocimeter proposed as a new-generation instrument for CFHT. SPIRou aims in particular at becoming world-leader on two forefro…
