Discovery of the $λ$ Bootis phenomenon in an early B-type star

J. Olbermann, P. Aschenbrenner, N. Przybilla

Chemically peculiar A-type stars of the $λ$ 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…
