Discovery of the Bootis phenomenon in an early B-type star
J. Olbermann, P. Aschenbrenner, N. Przybilla
Chemically peculiar A-type stars of the Boo class are characterised by depletions of refractory elements and normal volatile species. Their formation channel(s) have not yet be…
Quantitative spectroscopy of single and multiple OB-type stars. Non-LTE spectrum analysis with machine learning
P. Aschenbrenner, N. Przybilla
The plethora of spectra of OB-type stars in observatory archives and the much larger numbers to come from the WEAVE and 4MOST spectroscopic facilities require efficient, but also a…
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…
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…
Quantitative spectroscopy of late O-type main-sequence stars with a hybrid non-LTE method
Patrick Aschenbrenner, Norbert Przybilla, Keith Butler
Context. Late O-type stars at luminosities show weak winds with mass-loss rates lower than 10 yr. This implies that their photos…
