The available data on nuclear fusion cross sections important to energy generation in the
Sun and other hydrogen-burning stars and to solar neutrino production are summarized and …

The Sun provides a critical benchmark for the general study of stellar structure and
evolution. Also, knowledge about the internal properties of the Sun is important for the …

Context. Ultra-hot Jupiters are excellent laboratories for the study of exoplanetary
atmospheres. WASP-121b is one of the most studied; many recent analyses of its …

Double-diffusive convection is a mixing process driven by the interaction of two fluid
components which diffuse at different rates. Leading expert Timour Radko presents the first …

Context. The chemical composition of the Sun is a fundamental yardstick in astronomy,
relative to which essentially all cosmic objects are referenced. As such, having accurate …

Context. Thanks to the importance that the star-planet relation has to our understanding of
the planet formation process, the precise determination of stellar parameters for the ever …

Context. This is the fourth paper in a series showing the results of planet population
synthesis calculations. In Paper I, we presented our methods. In Paper II, we compared the …

We derive atmospheric parameters and lithium abundances for 671 stars and include our
measurements in a literature compilation of 1381 dwarf and subgiant stars. First, a" lithium …

Exoplanets with relatively clear atmospheres are prime targets for detailed studies of
chemical compositions and abundances in their atmospheres. Alkali metals have long been …

Following up our recent analysis devoted to the impact of non steady accretion on the
location of young low-mass stars or brown dwarfs in the Herzsprung-Russell diagram, we …
