The SPIRou Legacy Survey: near-infrared and optical radial velocity analysis of Gl 480 and Gl 382 using SPIRou, HARPS and CARMENES spectrographs
M. Ould-Elhkim, C. Moutou, J-F. Donati +13
Context: Advancements in the field of exoplanetary research have extended radial velocity (RV) observations from the optical to the near-infrared (nIR) domain. M dwarf stars, chara…
TOI-4860 b, a short-period giant planet transiting an M3.5 dwarf
J. M. Almenara, X. Bonfils, E. M. Bryant +47
We report the discovery and characterisation of a giant transiting planet orbiting a nearby M3.5V dwarf (d = 80.4 pc, = 15.1 mag, =11.2 mag, R = 0.358 0.015 R$…
A sub-Neptune planet around TOI-1695 discovered and characterized with SPIRou and TESS
F. Kiefer, G. Hébrard, E. Martioli +39
TOI-1695 is a V-mag=13 M-dwarf star from the northern hemisphere at 45pc from the Sun, around which a 3.134-day periodic transit signal from a super-Earth candidate was identif…
Uncovering the true periods of the young sub-Neptunes orbiting TOI-2076
Hugh P. Osborn, Andrea Bonfanti, Davide Gandolfi +93
Context: TOI-2076 is a transiting three-planet system of sub-Neptunes orbiting a bright (G = 8.9 mag), young ( Myr) K-type star. Although a validated planetary system, th…
TOI-1759 b: a transiting sub-Neptune around a low mass star characterized with SPIRou and TESS
Eder Martioli, Guillaume Hébrard, Pascal Fouqué +57
We report the detection and characterization of the transiting sub-Neptune TOI-1759 b, using photometric time-series from TESS and near infrared spectropolarimetric data from SPIRo…
Decoding the radial velocity variations of HD41248 with ESPRESSO
J. P. Faria, V. Adibekyan, E. M. Amazo-Gómez +13
Twenty-four years after the discoveries of the first exoplanets, the radial-velocity (RV) method is still one of the most productive techniques to detect and confirm exoplanets. Bu…
Is the activity level of HD 80606 influenced by its eccentric planet?
P. Figueira, A. Santerne, A. Suárez Mascareño +14
Aims: Several studies suggest that the activity level of a planet-host star can be influenced by the presence of a close-by orbiting planet. Moreover, the interaction mechanisms th…
