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 astrophysical characterisation of sources is among the major new data
products in the third Gaia Data Release (DR3). In particular, there are stellar parameters for …

Planck has mapped the microwave sky in temperature over nine frequency bands between
30 and 857 GHz and in polarization over seven frequency bands between 30 and 353 GHz …

We describe the automated spectral classification, redshift determination, and parameter
measurement pipeline in use for the Baryon Oscillation Spectroscopic Survey (BOSS) of the …

Context. The quest to detect dormant stellar-mass black holes (BHs) in massive binaries (ie
OB+ BH systems) is challenging; only a few candidates have been claimed to date, all of …

The chemical compositions of stars encode the history of the universe and are thus
fundamental for advancing our knowledge of astrophysics and cosmology. However …

We present models that predict spectra of old-and intermediate-aged stellar populations at
2.51 Å (FWHM) with varying [α/Fe] abundance. The models are based on the MILES library …

Aims. Even the most precise radial-velocity instruments gather high-resolution spectra that
present systematic errors that a data reduction pipeline cannot identify and correct for …

Theoretical stellar libraries have been increasingly used to overcome limitations of empirical
libraries, eg by exploring atmospheric parameter spaces not well represented in the latter …

We present the first release of the MaNGA Stellar Library (MaStar), which is a large, well-
calibrated, high-quality empirical library covering the wavelength range 3622–10354 Å at a …
