Period switching in the symbiotic star BX Mon.
LEIBOWITZ E.M. and FORMIGGINI L.
Abstract (from CDS):
We suggest that the origin of the major oscillations lies in periodic episodes of mass accretion from the M giant on to the hot component of the system. After the gap, they are correlated with the periastron passage of the system and therefore appear with the binary period. Before the gap, the oscillations appeared with the diurnal cycle of an observer on the surface of the rotating M giant, whose Sun is the hot component. The event of the period switching is possibly related to an intensive magnetic activity in the outer layers of the giant star.
