There has been an incredibly large investment in obtaining high-resolution stellar spectra for
determining chemical abundances of stars. This information is crucial to answer …

Context. The census of stellar and substellar companions of nearby stars is largely
incomplete, in particular toward the low-mass brown dwarf and long-period exoplanets. It is …

ABSTRACT The Galactic Archaeology with HERMES (GALAH) survey is a large-scale stellar
spectroscopic survey of the Milky Way, designed to deliver complementary chemical …

High-resolution spectroscopy (R≥ 25,000) has recently emerged as one of the leading
methods for detecting atomic and molecular species in the atmospheres of exoplanets …

Evolved cool stars of various masses are major cosmic engines, delivering substantial
mechanical and radiative feedback to the interstellar medium through strong stellar winds …

The recent inference of sulfur dioxide (SO2) in the atmosphere of the hot (approximately
1,100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations …

Aims. The Radial Velocity Spectrometer (RVS) on board the ESA satellite mission Gaia has
no calibration device. Therefore, the radial velocity zero point needs to be calibrated with …

We present the YBC database of stellar bolometric corrections, in which we homogenise
widely used theoretical stellar spectral libraries and provide BCs for many popular …

Context. The Gaia Data Release 2 (DR2) contains the first release of radial velocities
complementing the kinematic data of a sample of about 7 million relatively bright, late-type …

We explore the three-dimensional properties of convective, luminous (L≈ 10 4.5–10 5 L⊙),
hydrogen-rich envelopes of red supergiants (RSGs) based on radiation hydrodynamic …
