Six transiting planets and a chain of Laplace resonances in TOI-178
A. Leleu, Y. Alibert, N. C. Hara +152
Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the…
Refining the transit timing and photometric analysis of TRAPPIST-1: Masses, radii, densities, dynamics, and ephemerides
Eric Agol, Caroline Dorn, Simon L. Grimm +32
We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST and K2 transit time measurements, and…
A super-Earth and a sub-Neptune orbiting the bright, quiet M3 dwarf TOI-1266
B. -O. Demory, F. J. Pozuelos, Y. Gomez Maqueo Chew +70
We report the discovery and characterisation of a super-Earth and a sub-Neptune transiting the bright (), quiet, and nearby (37 pc) M3V dwarf TOI-1266. We validate the plane…
The occurrence rate of exoplanets orbiting ultracool dwarfs as probed by K2
Marko Sestovic, Brice-Olivier Demory
With the discovery of a planetary system around TRAPPIST-1, there has been a surge of interest in ultracool dwarfs as potential planet hosts. Planetary systems around ultracool dwa…
Co-orbital exoplanets from close period candidates: The TOI-178 case
Adrien Leleu, Jorge Lillo-Box, Marko Sestovic +6
Despite the existence of co-orbital bodies in the solar system, and the prediction of the formation of co-orbital planets by planetary system formation models, no co-orbital exopla…
The 0.8-4.5m broadband transmission spectra of TRAPPIST-1 planets
E. Ducrot, M. Sestovic, B. M. Morris +18
The TRAPPIST-1 planetary system represents an exceptional opportunity for the atmospheric characterization of temperate terrestrial exoplanets with the upcoming James Webb Space Te…
Investigating hot-Jupiter inflated radii with hierarchical Bayesian modelling
Marko Sestovic, Brice-Olivier Demory, Didier Queloz
As of today, hundreds of hot Jupiters have been found, yet the inflated radii of a large fraction of them remain unexplained. It is still unclear whether a single inflation mechani…
The nature of the TRAPPIST-1 exoplanets
Simon L. Grimm, Brice-Olivier Demory, Michaël Gillon +23
Context. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation a…
A seven-planet resonant chain in TRAPPIST-1
Rodrigo Luger, Marko Sestovic, Ethan Kruse +30
The TRAPPIST-1 system is the first transiting planet system found orbiting an ultra-cool dwarf star. At least seven planets similar to Earth in radius and in mass were previously f…
