TL;DR: The observations reveal that at least seven planets with sizes and masses similar to those of Earth revolve around TRAPPIST-1, and the six inner planets form a near-resonant chain, such that their orbital periods are near-ratios of small integers.
Journal ArticleDOI
Temperate Earth-sized planets transiting a nearby ultracool dwarf star
Michaël Gillon,Emmanuel Jehin,Susan M. Lederer,Laetitia Delrez,Julien de Wit,Artem Burdanov,Valérie Van Grootel,Adam J. Burgasser,Amaury H. M. J. Triaud,Cyrielle Opitom,Brice-Olivier Demory,D. K. Sahu,Daniella C. Bardalez Gagliuffi,Pierre Magain,Didier Queloz +14 more
TL;DR: In this paper, the detection of three Earth-sized planets transiting a very nearby (12 parsec) ultracool dwarf star of only 8% of the mass of the Sun was reported.
Journal ArticleDOI
Spin-orbit angle measurements for six southern transiting planets New insights into the dynamical origins of hot Jupiters
Amaury H. M. J. Triaud,A. Collier Cameron,Didier Queloz,David R. Anderson,Michaël Gillon,Leslie Hebb,Coel Hellier,B. Loeillet,Pierre F. L. Maxted,Michel Mayor,Francesco Pepe,Don Pollacco,Damien Ségransan,Barry Smalley,Stéphane Udry,Richard G. West,Peter J. Wheatley +16 more
TL;DR: The goal is to measure the degree of alignment between planetary orbits and stellar spin axes, to search for potential correlations with eccentricity or other planetary parameters and to measure long term radial velocity variability indicating the presence of other bodies in the system.
Journal ArticleDOI
Spin-orbit angle measurements for six southern transiting planets; New insights into the dynamical origins of hot Jupiters
Amaury H. M. J. Triaud,Andrew Collier Cameron,Didier Queloz,David R. Anderson,Michaël Gillon,Leslie Hebb,Coel Hellier,Benoît Loeillet,Pierre F. L. Maxted,Michel Mayor,Francesco Pepe,Don Pollacco,Damien Ségransan,Barry Smalley,Stéphane Udry,Richard G. West,Peter J. Wheatley +16 more
TL;DR: For transiting hot Jupiters, the Rossiter-McLaughlin effect allows the measurement of the sky-projected angle beta between the stellar rotation axis and a planet's orbital axis as discussed by the authors.

TL;DR: In this article, the authors used a genetic algorithm coupled with a full N-body integrator to estimate the masses and densities of the TRAPPIST-1 exoplanets.
