Abstract:
The period variations of TV Cassiopeiae between 1901 and 1977 are discussed in the light of the period change model proposed by Biermann and Hall. During each period decrease 4.0 x 10¯⁶M☉ of mass is transferred from the secondary star to the primary. The average observable mass transfer rate is found to be 4.3 x 10¯⁷M☉ yr¯¹. This average rate corresponds to the thermal time-scale of the mass-losing star.
