TL;DR: The PLATO 2.0 instrument consists of 34 small aperture telescopes (32 with 25 sec readout cadence and 2 with 2.5 sec candence) providing a wide field-of-view (2232 deg2) and a large photometric magnitude range (4-16 mag) as discussed by the authors.

TL;DR: The PLATO 2.0 mission as discussed by the authors has been selected for ESA's M3 launch opportunity (2022/24) to provide accurate key planet parameters (radius, mass, density and age) in statistical numbers.

TL;DR: In this paper, the authors reported the discovery of a medium-strength magnetic field on the young, massive star? Sco (B0.2V), which becomes the third-hottest magnetic star known.

TL;DR: In this article, a small sample of stars ranging from spectral type M0 to M8 was used to investigate how dynamo processes operate in stars on both sides of the full convection threshold (spectral type M4).
