Long-Period Variables in the Large Magellanic Cloud: Results from MACHO and 2MASS

Fraser, Oliver J; Hawley, Suzanne; Cook, Kem H; Keller, Stefan

Description

We use the 8 year light-curve database from the MAssive Compact Halo Objects project together with infrared colors and magnitudes from the Two Micron All Sky Survey to identify a sample of 22,000 long-period variables in the Large Magellanic Cloud (referred to hereafter as LMC LPVs). A period-luminosity diagram of these stars reveals six well-defined sequences, in substantial agreement with previous analyses of samples from the Optical Gravitational Lensing Experiment. In our analysis we...[Show more]
