Faint southern spectrophotometric standard stars
N. P. Gentile Fusillo, S. Moehler, N. Przybilla +4
Context. The advent of the Extremely Large Telescope (ELT) will increase the collecting area by more than an order of magnitude compared to the individual Unit Telescopes of the Ve…
The present-day cosmic phosphorus abundance
P. Aschenbrenner, K. Butler, N. Przybilla
The present-day phosphorus abundance in the solar neighbourhood is determined from a sample of OB-type stars. This is in order to constrain the endpoint of the galactochemical evol…
Newborn Be star systems observed shortly after mass transfer
Th. Rivinius, R. Klement, S. D. Chojnowski +24
Many classical Be stars acquire their very rapid rotation by mass and angular-momentum transfer in massive binaries. Short-lived intermediate-phase objects have only been discovere…
Quantitative spectroscopy of multiple OB stars: I. The quadruple system HD 37061 at the centre of Messier 43
Patrick Aschenbrenner, Norbert Przybilla
The majority of massive stars are located in binary or multiple star systems. Compared to single stars, these objects pose additional challenges to quantitative analyses based on m…
