On the pulsation modes and masses of RGB OSARGs

OSARG (OGLE Small Amplitude Red Giants) variables are RGB or AGB stars that show multi-periodic light variations with periods of about 10-100 days. Comparing linear nonadiabatic pulsation periods and period ratios with observed ones, we determined pulsation modes and masses of the RGB OSARG variable...
