TL;DR: For metal-poor benchmark stars, disagreement has been reported in this paper, where a set of 'benchmark' stars whose fundamental properties are well determined are used for validation of large stellar surveys of the Milky Way.

TL;DR: In this paper, the authors used the data from the Gaia Early Data Release 3 (EDR3) to select different populations and components and to calculate the distances and velocities in the direction of the anticentre.

TL;DR: In this article, the radial velocity zero point of the ESA satellite mission Gaia is calibrated with stars that are proved to be stable at a level of 300 m/s during the Gaia observations.

TL;DR: In this paper, the authors presented a catalog of the expected close conjunctions of alpha Cen A with distant stars until 2050, including the most favorable stellar conjunctions within at least the next three decades.

TL;DR: In this article, the authors introduce the mixing resulting from the radiative diffusivity associated with radiative viscosity in the calculation of stellar evolution models and find that this mixing significantly diminishes the efficiency of the gravitational settling in the external layers of stellar models corresponding to types earlier than ≈ G.
