Search for rapid spectral feature variations in chemically peculiar star HR4330.

SRIRAGHAVAN S.M. and BABU G.S.D.

Abstract (from CDS):

The chemically peculiar star HR4330 (=HD96707, EP-UMa) was observed using the 2-m Himalayan Chandra Telescope at the Indian Astronomical Observatory, Hanle, India, for studying the variations in its spectral features. It was found that the spectral features of Caii 3933Å and Srii 4077Å were showing rapid variations in their equivalent widths with a periodicity of 0.28 ± 0.02d. Such short-term variations suggest that there could be a dynamically active surface with rapid variation in the conditions of the stellar atmosphere.
