TL;DR: In this article, the authors perform a study of stellar flares for the 24,809 stars observed with 2 minute cadence during the first two months of the TESS mission and identify 1228 flaring stars, 673 of which are M-dwarfs.

TL;DR: In this paper, the authors conducted a far-ultraviolet flare survey of six M dwarfs from the recent MUSCLES (Measurements of the Ultraviolet Spectral Characteristics of Low-mass Exoplanetary Systems) observations, as well as four highly active and inactive stars with archival data, and found the active-M dwarfs to be about 10× more energetic than inactive-M-star flares.

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.
