Revisiting TOI-4438 and TOI-442 planetary systems with new observations from SPIRou and TESS
J. Serrano Bell, G. Hébrard, E. Martioli +26
We present a comprehensive re-analysis of two star-planet systems: TOI-4438, an M3.5V star hosting a mini-Neptune in a 7.4-day orbit, and TOI-442, an M1V star with a 4-day period p…
Unstable magnetospheric accretion on the T Tauri star TW Hya
J. -F. Donati, P. I. Cristofari, C. Moutou +9
In this paper we present new spectropolarimetric and velocimetric observations of the prototypical classical T Tauri star TW Hya obtained with SPIRou at the Canada-France-Hawaii Te…
Magnetic geometry of M dwarfs in the southern PLATO field
M. Diez, P. I. Cristofari, J. Morin +9
M dwarfs are the most abundant stars in the Galaxy and exhibit diverse magnetic behaviours. Understanding their large-scale magnetic fields is essential to study stellar dynamos an…
The circumstellar environment of the young, low-mass dipper star JH 223. Accretion and large-scale magnetic field topology
T. P. Freitas, J. Bouvier, B. Zaire +11
Studies of magnetospheric accretion and magnetic field topology in T Tauri stars have advanced over the years, but their applications to fully convective, very-low-mass T Tauri sta…
Super-Earth masses and stellar abundances from NIRPS reveal tentative evidence for water-rich formation around M dwarfs
Drew Weisserman, Nicole Gromek, Ryan Cloutier +98
Tracing the compositional link between terrestrial super-Earths and their host stars provides clues to their dominant formation pathway. By constraining the stellar abundances of r…
Confirmation of the hot super-Neptune TOI-672 b with NIRPS and HARPS and Insights into the Neptunian desert around M dwarfs
Ares Osborn, Ryan Cloutier, Vincent Bourrier +65
The Neptunian desert is a distinct lack of Neptune-sized planets at short orbital periods, purportedly carved by photoevaporation and tidal circularization following high-eccentric…
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…
