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…

The EDIBLES survey. X. The 6196 Ã diffuse interstellar band: Identification of side DIBs as an indication of a small carrier molecule
A. Ebenbichler, M. OnÄák, N. Przybilla +11
Context: Numerous studies of diffuse interstellar band (DIB) profiles have detected substructures, which in turn suggests that large molecules are acting as their carriers. However…
