Two warm Earth-sized exoplanets and an Earth-sized candidate in the M5V-M6V binary system TOI-2267

S. Zúñiga-Fernández, F. J. Pozuelos, M. Dévora-Pajares +63

We report two warm Earth-sized exoplanets orbiting the close binary TOI-2267 (M5+M6, separation ~8 au). Data from TESS and ground-based facilities confirm the planets, but we canno…

Detailed Architecture of the L 98-59 System and Confirmation of a Fifth Planet in the Habitable Zone

Charles Cadieux, Alexandrine L'Heureux, Caroline Piaulet-Ghorayeb +12

The L 98-59 system, identified by TESS in 2019, features three transiting exoplanets in compact orbits of 2.253, 3.691, and 7.451 days around an M3V star, with an outer 12.83-day n…

A New Brown Dwarf Orbiting an M star and An Investigation on the Eccentricity Distribution of Transiting Long-Period Brown Dwarfs

Tianjun Gan, Charles Cadieux, Shigeru Ida +32

The orbital eccentricities of brown dwarfs encode valuable information of their formation and evolution history, providing insights into whether they resemble giant planets or stel…

A transiting giant planet in orbit around a 0.2-solar-mass host star

Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56

Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…

Escaping Helium and a Highly Muted Spectrum Suggest a Metal-Enriched Atmosphere on Sub-Neptune GJ3090b from JWST Transit Spectroscopy

Eva-Maria Ahrer, Michael Radica, Caroline Piaulet-Ghorayeb +27

Sub-Neptunes, the most common planet type, remain poorly understood. Their atmospheres are expected to be diverse, but their compositions are challenging to determine, even with JW…

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…

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…
