BD Her: Neue Ergebnisse.

STEINBACH H.-M.

Abstract (from CDS):

BD Her was observed in August-September 2007 by TAROT (CCD, GEOS-Group) and by myself. The observations give hints that BD Her changes its period on a short timescale (days rather than weeks) by a value of roughly 1%. Further observations are needed to get a better unter- standig of the star.
