Mass Flow due to Heating in a Binary System: Application to U Cephei
Published online by Cambridge University Press: 12 April 2016
Abstract
We have investigated the possibility of mass flow due to the heating of the cooler component in a close binary system. The heating may be caused by irradiation from the hotter companion or by other mechanisms such as the spacial coincidence of non-linear “g-mode” oscillations in the cooler star. The 2.4-day period binary U Cep, in which gas streaming has been observed, has been chosen for model calculations. Preliminary results show that such a heating of the lower atmosphere of the cooler star could lead to mass flow at an average rate of 10-9 to 10-7 solar mass per year without the star's necessarily filling its critical Roche surface.
