On the observability of geometric pulsation of M-type Mira variables

Ireland, M. J; Scholz, M; Wood, Peter R

Description

The geometric pulsation of an M-type Mira variable as a function of phase is studied by means of a series of complete self-excited models that follows two successive cycles with time intervals of about 0.1 cycles. Pulsation of the optical-depth diameter in a real-continuum bandpass in the near-infrared is predicted to be a simple sinusoidal-like motion. Pulsation of interferometrically measurable diameters is close to this motion only in the case of very small molecular-band contamination of...[Show more]
