Radial velocity monitoring of possible close red giant binary systems
MACHO observations show that approximately 25% of semi-regular red variables in the LMC have a secondary period similar to10 times longer than the primary period of pulsation, which is usually the first overtone pulsation mode in these stars. Wood et al. (1999) have suggested that the long secondary...
