J/A+A/310/164       Line profile variations in eta Ori           (De Mey+, 1996)

The early-type multiple system Eta Orionis. II. Line profile variations in component Ab De Mey K., Aerts C., Waelkens C., van Winckel H. <Astron. Astrophys. 310, 164 (1996)> =1996A&A...310..164D (SIMBAD/NED BibCode)
ADC_Keywords: Binaries, spectroscopic; Stars, variable; Radial velocities Keywords: stars: binaries: eclipsing - stars: binaries: spectroscopic - stars: oscillations - stars: individual: Eta Orionis - line: profiles Description: Eta Orionis (HD35411) is a multiple system which consists of at least four early B-type stars. In the present paper we focus on the double-lined spectroscopic eclipsing pair Aab, and in particular on component Ab, which is a remarkable intrinsically variable star. The presence of this variable in an eclipsing system enables us to determine accurately its mass, radius, inclination angle and rotation period.
