Seven temperate terrestrial planets around the nearby ultracool dwarf star TRAPPIST-1
One aim of modern astronomy is to detect temperate, Earth-like exoplanets that are well
suited for atmospheric characterization. Recently, three Earth-sized planets were detected …

Refining the transit-timing and photometric analysis of TRAPPIST-1: masses, radii, densities, dynamics, and ephemerides
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 …

Temperate Earth-sized planets transiting a nearby ultracool dwarf star
Star-like objects with effective temperatures of less than 2,700 kelvin are referred to as
'ultracool dwarfs'. This heterogeneous group includes stars of extremely low mass as well as …
