Ellipsoidal Variability and Long Secondary Periods in Macho Red Giant Stars
We present a period-luminosity-amplitude analysis of 5899 red giant and binary stars in the Large Magellanic Cloud, using publicly available observations of the MACHO Project. For each star, we determined new periods, which were double-checked in order to exclude aliases and false periods. The period-luminosity (P-L) relations confirm the existence of a short-period, small-amplitude P-L sequence at periods shortward of sequence A. We point out that the widely accepted sequence of eclipsing...[Show more]
