The multiple spectroscopic and photometric periods of DI Cru ≡ WR 46 1

Abstract

In an effort to determine the orbital period of the enigmatic star DI Cru ≡ WR 46 ≡ HD 104994, we made photometric and spectroscopic observations of this object between 1996 and 2002. Both photometric and spectroscopic characteristics are quite complex. The star is highly variable on short (few hours) as well as on long (few months) time-scales. The optical… (More)
