The generalised Lomb-Scargle periodogram. A new formalism for the floating-mean and Keplerian periodograms
TL;DR: The Lomb-Scargle periodogram is a common tool in the frequency analysis of unequally spaced data equivalent to least-squares fitting of sine waves as discussed by the authors, and it can be used to detect eccentric orbits of exoplanets.

TL;DR: Observations reveal the presence of a small planet with a minimum mass of about 1.3 Earth masses orbiting Proxima with a period of approximately 11.2 days at a semi-major-axis distance of around 0.05 astronomical units.

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.
