TL;DR: In this article, the effect of burst accretion on the internal structure of low-mass and solar type stars was studied and it was shown that episodic accretion can produce objects with significantly higher central temperatures than the ones of the non-accreting counterparts of same mass and age.

TL;DR: In this article, the finite-volume based, cell-centered, and time-explicit hydrodynamics solver of A-MaZe was extended such that the scheme is now well-balanced in both momentum and energy.

TL;DR: In this paper, the authors summarize the present knowledge of the behaviour of the mass-radius relationship from solar-type stars down to terrestrial planets, across the regime of substellar objects, brown dwarfs and giant planets.

TL;DR: In this article, the authors investigate the evolution, final fate, and nucleosynthetic yields of rotating and non-rotating very massive stars (VMS) of zero metallicity.

TL;DR: In this article, the pulsational properties of RSG models were investigated by means of linear and non-linear calculations, and the authors concluded that changes in global stellar properties during the last few 10 4 yr before core collapse may lead to drastic changes in the pulsations and wind properties of pre-supernova stars, with marked consequences for the imme- diate presupernova structure of the star and the circumstellar medium.
