Revisiting TOI-4438 and TOI-442 planetary systems with new observations from SPIRou and TESS
J. Serrano Bell, G. Hébrard, E. Martioli +26
The study re‑examines two M‑dwarf planetary systems, TOI‑4438 and TOI‑442, using new TESS transit data and high‑resolution near‑infrared spectroscopy from SPIRou, refining the plan…
The SPIRou Legacy Survey: Detection of a nearby world orbiting in the habitable zone of Gl725B achieved by correcting strong telluric contamination in near-infrared radial velocities with WAPITI
M. Ould-Elhkim, C. Moutou, J. -F. Donati +15
M dwarfs are prime targets in the search for exoplanets because of their prevalence and because low-mass planets can be better detected with radial velocity (RV) methods. In partic…
Characterizing planetary systems with SPIRou: questions about the magnetic cycle of 55 Cnc A and two new planets around B
C. Moutou, P. Petit, P. Charpentier +12
One of the first exoplanet hosts discovered thirty years ago, the star 55 Cnc has been constantly observed ever since. It is now known to host at least five planets with orbital pe…
Characterizing planetary systems with SPIRou: Detection of a sub-Neptune in a 6-day period orbit around the M dwarf Gl 410
A. Carmona, X. Delfosse, M. Ould-Elhkim +42
The search for exoplanets around nearby M dwarfs represents a crucial milestone in the census of planetary systems in the vicinity of our Solar System. Since 2018 our team is carry…
