TL;DR: The Gaia-ESO Public Spectroscopic Survey has begun and will obtain high quality spectroscopy of some 100000 Milky Way stars, in the field and in open clusters, down to magnitude 19, systematically.

TL;DR: In this paper, a sample of 28 well-known spectroscopically-identified magnetic Ap/Bp stars, with weak, poorly-determined or previously undetected magnetic fields, was used to explore the weak part of the magnetic field distribution of Ap/bp stars.

TL;DR: In this article, the authors explore the characteristics of 42 solar X-class flares that were observed between February 2011 and November 2014, with data from the Solar Dynamics Observatory (SDO) and other sources.

TL;DR: In this article, the magnetic field topology of the late-B magnetic chemically peculiar star CU Vir has been analyzed using high-resolution spectropolarimetric observations covering the entire rotational period.

TL;DR: In this paper, the authors present a detailed abundance analysis of nine of the potential main targets using the semi-automatic software , and find that it is necessary to measure abundances extracted from each line relative to the abundances found from a spectrum of the Sun in order to remove systematic errors.
