TL;DR: The atmospheric escape rates numerically and analytically for the planets of the TRAPPIST-1 system are determined and it is shown that the outer planets are potentially likely to retain their atmospheres over billion-year timescales.

TL;DR: In this article, the authors adapted a multi-species MHD model originally developed for Venus and Mars and computed the ion escape losses from Proxima Centauri b (PCb) and found that ion escape rates are about two orders of magnitude higher than the terrestrial planets of our solar system if PCb is unmagnetized.

TL;DR: In this article, a general theory of the plasmoid instability is formulated by means of a principle of least time, and scaling relations for the final aspect ratio, transition time to rapid onset, growth rate, and number of plasmoids are derived and shown to depend on the initial perturbation amplitude, the characteristic rate of current sheet evolution, and the Lundquist number.

TL;DR: In this paper, a general theory of the onset and development of plasmoid instability is formulated by means of a principle of least time, and scaling relations for the final aspect ratio, transition time to rapid onset, growth rate, and number of plasms are derived, and shown to depend on the initial perturbation amplitude.

TL;DR: In this article, the authors derived scaling laws for the plasmoid instability in resistive and visco-resistive current sheets that evolve over time, based on a principle of least time that enables them to determine the properties of the reconnecting current sheet (aspect ratio and elapsed time).
