Stellar Winds in Time
TL;DR: In this article, the effects of stellar winds on planetary atmospheres are estimated empirically using the ability to study the winds of stars of various ages and activity levels, but this is not easy to do as the coronal winds of solar-like stars are very hard to detect.

TL;DR: In this paper, the authors developed a methodology to determine stellar abundances of elements other than iron for M dwarfs from high-resolution, optical spectra using principal component analysis and sparse Bayesian's methods.

Disappearance of the extended main sequence turn-off in intermediate age clusters as a consequence of magnetic braking
Cyril Georgy,Corinne Charbonnel,Corinne Charbonnel,Louis Amard,Nate Bastian,Sylvia Ekström,Carmela Lardo,A. Palacios,Patrick Eggenberger,I. Cabrera-Ziri,François Gallet,Nadège Lagarde +11 more
TL;DR: In this paper, the authors investigated the maximal mass for which this braking occurs at different metallicities, and determined the age above which no extended MS turn-off is expected in clusters.

Magnetic braking of accreting T Tauri stars: Effects of mass accretion rate, rotation, and dipolar field strength
TL;DR: In this paper, the authors performed 2.5D magnetohydrodynamic, axisymmetric, time-dependent simulations of star-disk interaction with an initial dipolar magnetic field structure, and a viscous and resistive accretion disk.

Efficiency of O–C diagrams as diagnostic tools for long-term period variations - I. Wind-driven mass loss and magnetic braking
TL;DR: In this paper, the credibility of an O-C diagram analysis is investigated when long-term processes are examined in binary systems and the minimum time intervals that observations are expected to span for a physical mechanism to be detectable by means of O-c diagram analysis.
