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.

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.

TL;DR: The TRAPPIST-1 system is the first transiting planet system found orbiting an ultra-cool dwarf star as mentioned in this paper, which was unconstrained until now, and has a radius of 0.715 Earth radii and an equilibrium temperature of 169 K, placing it at the snow line.

TL;DR: The TRAPPIST-1 system is the first transiting planet system found orbiting an ultra-cool dwarf star as discussed by the authors, which was unconstrained until now, and has a radius of 0.727 Earth radii and an equilibrium temperature of 173 K.
Journal ArticleDOI
The habitability of Proxima Centauri b - II. Possible climates and observability

TL;DR: In this article, a 3D Global Climate Model (GCM) is used to simulate Proxima b's atmosphere and water cycle for its two likely rotation modes (1:1 and 3:2 resonances) while varying the unconstrained surface water inventory and atmospheric greenhouse effect.
