A Buddy for Betelgeuse: Binarity as the Origin of the Long Secondary Period in α Orionis
We predict the existence of α Ori B, a low-mass companion orbiting Betelgeuse. This is motivated by the presence of a 2170 day long secondary period (LSP) in Betelgeuse’s lightcurve, a periodicity that is ≈5 times longer than the star’s 416 day fundamental radial pulsation mode. While binarity is cu...
