Radial velocity detection of the TRAPPIST-1 planetary system with SPIRou and NIRPS

Alexandrine L'Heureux, René Doyon, Charles Cadieux +57

The TRAPPIST-1 system is well-known for its seven transiting Earth-sized exoplanets. It has been extensively studied and characterized, notably with transit timing variations (TTVs…

Dynamical formation of long-period exoplanets systems in evolving binary stars

Isabel J. Lima, Rafael R. Sousa, Silvia M. Giuliatti Winter +4

The dynamical formation and evolution of long-period giant exoplanets have not been well constrained due to the few observational parameters. In this study, we explore the dynamica…

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…

Giant Planets and Eccentric Orbits Are Common Around Galactic Thick Disc Stars

Thiago Ferreira, Jhon Yana Galarza, Henrique Reggiani +15

Planet formation in the Galactic thick disc is expected to be inefficient---low solid reservoirs, short disc lifetimes, and harsh irradiation environments should conspire to inhibi…

Modelling the Milky Way's exoplanet population based on cosmological galaxy simulations

Chloé Padois, Daniel del Ser, Friedrich Anders +7

In this paper we aim to simulate realistic exoplanet populations across different regions of the MW by combining state-of-the-art cosmological simulations of our Galaxy with exopla…

Detailed spectroscopic and photometric analysis of the remarkable planet-hosting wide binary system HD 202772A/B

Emiliano Jofré, Yilen Gómez Maqueo Chew, Romina Petrucci +15

We conducted a detailed spectroscopic and photometric characterization of the planet-hosting wide binary HD 202772A/B. No planet has been detected around HD 202772B, whereas HD 202…
