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: CARMENES (Calar Alto high-resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs) is a next-generation radial-velocity instrument under construction for the 3.5m telescope at the Calar Alto Observatory by a consortium of eleven Spanish and German institutions as discussed by the authors.

TL;DR: In this paper, the authors present an atlas of high-resolution M-dwarf spectra and compare the spectra to atmospheric models and demonstrate that in this spectroscopic range, the large amount of absorption features compensates for the intrinsic faintness of an M7 star.

TL;DR: In this article, preliminary asteroseismic results from Kepler on three G-type stars are presented, made at one-minute cadence during the first 33.5 days of science operations, reveal high signal-to-noise solar-like oscillation spectra in all three stars: about 20 modes of oscillation may be clearly distinguished in each star.

TL;DR: In this paper, the authors used a variety of independent codes and analyses that attempt to match the asteroseismic and spectroscopic constraints simultaneously to determine both the radius and the age of the subgiant KIC 11026764 with a precision near 1%.
