Orbital effects on the light curves of eta Car, BP Cru, and other eccentric binaries.
VAN GENDEREN A.M. and STERKEN C.
Abstract (from CDS):
We provide observational evidence that Eta Carinae's optical and near-infrared light peak around the periastron passages are in various respects similar to the periastron effects exhibited by other eccentric binaries, and therefore may well have the same physical cause. We list the magnitude of the effect for V380 Cyg = HD187879, V346 Cen = HD101837, V1647 Sgr = HD163708, V560 Car = HD93205, BP Cru = WRA977 and Eta Car = HD93308.
