Photodynamical modeling of TOI-4504 reveals its deeply resonant state and similarity to GJ 876

J. M. Almenara, R. Mardling, A. Leleu +15

The K-dwarf TOI-4504 hosts two giant planets in 2:1 mean-motion resonance, with orbital periods of 41.3 days (planet d) and 82.8 days (planet c). They exhibit among the largest kno…

The PAIRS project: a global formation model for planets in binaries. II. Gravitational perturbation effects from secondary stars

Arianna Nigioni, Julia Venturini, Emeline Bolmont +3

Roughly half of Sun-like stars have at least one stellar companion, whereas it is widely assumed that most known exoplanets orbit single stars, largely due to observational biases.…

The PAIRS project: a global formation model for planets in binaries. I. Effect of disc truncation on the growth of S-type planets

Julia Venturini, Arianna Nigioni, Maria Paula Ronco +2

Binary stars are as common as single stars. The number of detected planets orbiting binaries is rapidly increasing thanks to the synergy between transit surveys, Gaia and high-reso…

The quest for Magrathea planets. II. Orbital stability of exoplanets formed around double white dwarfs

Arianna Nigioni, Diego Turrini, Camilla Danielski +2

Planetary formation might occur at different stages of the stellar evolution of compact binaries. In recent years, the formation of second-generation planets has been tested in cir…

A four-planet system orbiting the old thick disk star TOI-1203

D. Gandolfi, A. Alnajjarine, L. M. Serrano +120

TOI-1203 is a bright (V=8.6) G3 V star known to host a transiting warm sub-Neptune on a 25.5 d orbit. Here we report on an intensive high-precision radial velocity and photometric…

CORALIE radial-velocity search for companions around evolved stars (CASCADES) IV: New planetary systems around HD 87816, HD 94890, and HD 102888 and an update on HD 121056

E. Fontanet, S. Udry, D. Ségransan +25

With around 200 detections of exoplanets around giant stars to date, our knowledge of the population of exoplanets orbiting evolved hosts more massive than the Sun remains limited.…
