TL;DR: In this paper, mass loss generally increases with coronal activity, but winds suddenly weaken at a certain activity threshold, suggesting that the magnetic field geometry associated with these spots may be inhibiting the winds.

TL;DR: In this article, the mass loss per unit face area is correlated with X-ray surface flux, and a power-law relation is derived for the solar-like GK dwarfs, showing that the solar wind may have been as much as 1000 times more massive in the distant past.

TL;DR: In this paper, the authors search the Hubble Space Telescope (HST) archive for previously unanalyzed observations of stellar H I Lyα emission lines, their primary purpose being to look for new detections of Lyα absorption from the outer heliosphere and to also search for analogous absorption of the astrospheres surrounding the observed stars.

TL;DR: Oscillons are localized, nonsingular, time-dependent, spherically symmetric solutions of nonlinear scalar field theories which, although unstable, are {ital extremely} long lived.

TL;DR: In this article, the authors investigate the response of the heliosphere to a temporally varying solar wind, and employ a multifluid model in which the charge exchange interaction between neutral hydrogen and protons is included self-consistently.
