An Emission-Line delta Scuti? The Case of V382 Vul and Other Variables in the Field of NGC 6882/5.
Abstract
During an observing run at the Dominion Astrophysical Observatory to collect spectra on northern δ Scuti stars we found a star with an emission line in the middle of the Hβ feature. This star was identified as V382 Vul and has been reported as an emission line star by Henize (1976) and as a δ Scuti by Pena et al. (1990). We will present photometric observations of this star to clarify its identification as both a δ Scuti variable and as an emission line star. In addition, we will present photometry on a sample of other stars from this region near the open cluster NGC 6882/5. The data presented will include VRI observations and observations from a new Hα index. Spectroscopic data will also be presented for V382 Vul and V381 Vul (another δ Scuti in the field).
