TL;DR: In this paper, the authors present the first set of realistic simulations and the preliminary design of the fiber injection unit that will be implemented in SPHERE, which is a demonstrator that will combine the capabilities of two flagship instruments installed on the ESO Very Large Telescope, the high-contrast exoplanet imager SpHERE and the high resolution spectrograph CRIRES+, with the goal of answering fundamental questions on the formation, composition and evolution of young planets.

TL;DR: In this paper, the authors provide evidence that stellar activity may be responsible for the mismatch between observations and theory through two different channels: inhibition of convection or effects of a significant starspot coverage.

TL;DR: In this paper, the authors apply the new generation of theoretical models of low-mass stars to secondaries in CVs, focussing on systems above the period gap, and confirm that the spectral type should be a good indicator of the donor mass.

TL;DR: In this article, the authors studied the impact of two-dimensional spherical shells on compressible convection using the MUltidimensional Stellar Implicit Code (MUSIC) and found that incorporating near-surface layers in the spherical shell can increase the amplitude of convective velocities, although the radial structure of deep convection is unchanged.

TL;DR: In this paper, the authors presented the consistent evolution of short-period exoplanets coupling the tidal and gravothermal evolution of the planet, and showed that the complete evolution equations of the Hut model is mandatory to derive correct tidal evolution histories, except if the system was formed with a nearly circular orbit.
