THE HOT COMPANION AND CIRCUMBINARY DISK OF THE Be STAR HR 2142
THE HOT COMPANION AND CIRCUMBINARY DISK OF THE Be STAR HR 2142
We present a spectroscopic investigation of the Be+sdO binary system HR 2142 that is based upon large sets of ultraviolet observations from the International Ultraviolet Explorer and ground-based H-alpha observations. We measured radial velocities for the Be star component from these spectra, and computed a revised orbit. In order to …
