TL;DR: The Evryscope as discussed by the authors is an under-construction 780 MPix telescope which is capable of detecting transiting exoplanets around every solar-type star brighter than mV = 12, providing at least few-millimagnitude photometric precision in longterm light curves.

TL;DR: In this article, the photochemical effects of NOx atmospheric species generated by particle events from Proxima Centauri's extreme stellar activity were modeled and shown that the repeated flaring may be sufficient to reduce the ozone of an Earth-like atmosphere by 90% within five years.

TL;DR: The Evryscope as mentioned in this paper is an under-construction 780 MPix telescope which covers 8,660 square degrees in each two-minute exposure; each night, 18,400 square degrees will be continuously observed for an average of approximately 6 hours.

TL;DR: In this article, the authors search for superflares from 4,068 cool stars in 2+ years of Evryscope photometry, focusing on those with high-cadence data from both TESS and TESS, and find 8 flares with amplitudes of 3+ g' magnitudes, with the largest reaching 5.6 magnitudes and releasing 10.2 erg.

TL;DR: In this article, the authors reported improved masses, radii, and densities for four planets in two bright M-dwarf systems, K2-3 and GJ3470, derived from a combination of new radial velocity and transit observations.
