Mass loss is a key process in the evolution of massive stars, and must be understood
quantitatively if it is to be successfully included in broader astrophysical applications such as …

After decades of fast-paced technical advances, optical/infrared (O/IR) interferometry has
seen a revolution in recent years:▪ The GRAVITY instrument at the Very Large Telescope …

Young and directly imaged exoplanets offer critical tests of planet-formation models that are
not matched by radial velocity surveys of mature stars. These targets have been extremely …

Context. Interpretation of interferometric observations of rapidly rotating stars requires a
good model of their surface effective temperature. Until now, laws of the form have been …

Context. Gas giants orbiting close to hot and massive early-type stars can reach dayside
temperatures that are comparable to those of the coldest stars. These 'ultra-hot Jupiters' …

Abstract Michigan InfraRed Combiner-eXeter (MIRC-X) is a new highly sensitive six-
telescope interferometric imager installed at the CHARA Array that provides an angular …

To understand how planetary systems form in the dusty disks around pre-main-sequence
stars, a detailed knowledge of the structure and evolution of these disks is required …

This article first reviews the basic physics of rotating stars and their evolution. The changes
of the mechanical and thermal equilibrium of rotating stars are examined. An important …

A complete accounting of nearby objects—from the highest-mass white dwarf progenitors
down to low-mass brown dwarfs—is now possible, thanks to an almost complete set of …

Massive stars, at least∼ 10 \sim10 times more massive than the Sun, have two key
properties that make them the main drivers of evolution of star clusters, galaxies, and the …
