Atmospheric mass loss from hot Jupiters irradiated by stellar superflares
TL;DR: In this paper, the authors employ a one-dimensional aeronomic model to study the reaction of the upper atmosphere of the hot Jupiter HD 209458b to the additional high-energy irradiation caused by a stellar flare.

Axisymmetric Simulations of Hot Jupiter-Stellar Wind Hydrodynamic Interaction
TL;DR: In this article, hydrodynamic simulations of the planetary upper atmosphere and its interaction with the stellar wind are carried out to understand the possible flow regimes and how they affect the Lyman-alpha transmission spectrum.

TL;DR: In this paper, the authors studied the escape of the upper atmospheres of the exoplanets of HD 189733 b and GJ 3470 b by analysing high-resolution HeI triplet absorption measurements and using a 1D hydrodynamic spherically symmetric model coupled with a non-local thermodynamic model for the He’s I triplet state.

Towards the ultimate conservative difference scheme V. A second-order sequel to Godunov's method
TL;DR: In this article, a second-order extension of the Lagrangean method is proposed to integrate the equations of ideal compressible flow, which is based on the integral conservation laws and is dissipative, so that it can be used across shocks.

Solar System Abundances and Condensation Temperatures of the Elements
TL;DR: In this article, solar photospheric and meteoritic CI chondrite abundance determinations for all elements are summarized and the best currently available photosphere abundances are selected, including the meteoritic and solar abundances of a few elements (e.g., noble gases, beryllium, boron, phosphorous, sulfur).

A Jupiter-Mass Companion to a Solar-Type Star
Michel Mayor,Didier Queloz +1 more
TL;DR: The presence of a Jupiter-mass companion to the star 51 Pegasi is inferred from observations of periodic variations in the star's radial velocity as discussed by the authors, which would be well inside the orbit of Mercury in our Solar System.
