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…

TOI-4552 b: A new ultra-short period rocky world revealed by NIRPS and TESS

Avidaan Srivastava, René Doyon, François Bouchy +57

A particularly intriguing subclass of rocky exoplanets are the ultra-short period (USP) worlds that orbit their host stars in less than a day. These planets are particularly rare a…

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…

Rotational modulation and long-term evolution of the small-scale magnetic fields of M dwarfs observed with SPIRou

P. I. Cristofari, J. -F. Donati, S. Bellotti +7

M dwarfs are known to host magnetic fields, impacting exoplanet studies and playing a key role in stellar and planetary formation and evolution. Observations revealed the long-term…

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$…

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…

Directly Imaging Rocky Planets from the Ground

B. Mazin, É. Artigau, V. Bailey +59

Over the past three decades instruments on the ground and in space have discovered thousands of planets outside the solar system. These observations have given rise to an astonishi…
