TRAPPIST-1: March 2017


We analyze short cadence K2 light curve of the TRAPPIST-1 system. Fourier analysis of the data suggests Prot=3.295±0.003 days.

Recently, astronomers announced the discovery that a star called TRAPPIST-1 is orbited by seven Earth-size planets. Three of the planets reside in the "habitable zone," the region around a star where liquid water is most likely to exist on the surface of a rocky planet.
