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
The study re‑examines two M‑dwarf planetary systems, TOI‑4438 and TOI‑442, using new TESS transit data and high‑resolution near‑infrared spectroscopy from SPIRou, refining the plan…
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…
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…
