Context. Early B-type stars are ideal indicators for present-day cosmic abundances since
they preserve their pristine abundances and typically do not migrate far beyond their birth …

ABSTRACT A representative sample of unevolved early B-type stars in nearby OB
associations and the field is analyzed to unprecedented precision using NLTE techniques …

Context. Early B-type stars are invaluable indicators of elemental abundances of their birth
environments. In contrast to the surrounding neutral interstellar matter (ISM) and H ii regions …

▪ Abstract The information on the chemical compositions of stars encoded in their spectra
plays a central role in contemporary astrophysics. Stellar element abundances are …

Context. Modern spectroscopy of early-type stars often aims at studying complex physical
phenomena such as stellar pulsation, the peculiarity of the composition of the photosphere …

The measurement of stellar properties such as chemical compositions, masses and ages,
through stellar spectra, is a fundamental problem in astrophysics. Progress in the …

Measures of the depletion of interstellar elements from the gas phase are usually derived by
assuming that the general composition of the interstellar medium is identical to that of the …

Context. Precise determinations of the chemical composition in early B-type stars constitute
fundamental observational constraints on stellar and galactochemical evolution. Carbon, in …

We present a homogeneous set of stellar atmospheric parameters (T eff, log g,[Fe/H]) for
MILES, a new spectral stellar library covering the range λλ 3525–7500 Å at 2.3 Å (FWHM) …

We investigate the conditions under which the first low-mass stars formed in the Universe by
confronting theoretical predictions governing the transition from massive Population III to low …
