Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903

Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173

Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…

ODUSSEAS: Upgraded version with new reference scale and parameter determinations for 82 planet-host M dwarf stars in SWEET-Cat

A. Antoniadis-Karnavas, S. G. Sousa, E. Delgado-Mena +2

Aims: Obtaining accurate derivations of stellar atmospheric parameters is crucial in the fields of stellar and exoplanet characterization. We present the upgraded version of our co…

The PLATO Mission

Heike Rauer, Conny Aerts, Juan Cabrera +842

PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…

An unusually low-density super-Earth transiting the bright early-type M-dwarf GJ 1018 (TOI-244)

A. Castro-González, O. D. S. Demangeon, J. Lillo-Box +34

Small planets located at the lower mode of the bimodal radius distribution are generally assumed to be composed of iron and silicates in a proportion similar to that of the Earth.…

Optical and near-infrared stellar activity characterization of the early M dwarf Gl~205 with SOPHIE and SPIRou

P. Cortes-Zuleta, I. Boisse, B. Klein +41

The stellar activity of M dwarfs is the main limitation for discovering and characterizing exoplanets orbiting them since it induces quasi-periodic RV variations. We aim to charact…

Metallicities in M dwarfs: Investigating different determination techniques

V. M. Passegger, A. Bello-García, J. Ordieres-Meré +17

Deriving metallicities for solar-like stars follows well-established methods, but for cooler stars such as M dwarfs, the determination is much more complicated due to forests of mo…

Warm terrestrial planet with half the mass of Venus transiting a nearby star

Olivier D. S. Demangeon, M. R. Zapatero Osorio, Y. Alibert +42

The advent of a new generation of radial velocity instruments has allowed us to break the one Earth-mass barrier. We report a new milestone in this context with the detection of th…

ODUSSEAS: A machine learning tool to derive effective temperature and metallicity for M dwarf stars

A. Antoniadis-Karnavas, S. G. Sousa, E. Delgado-Mena +3

Aims. The derivation of spectroscopic parameters for M dwarf stars is very important in the fields of stellar and exoplanet characterization. The goal of this work is the creation…
