Wolfgang Bacsa,Revathi Bacsa,Tim Myersith a complex profile. The intensity of the Hβ line appears to be modulated by the orbital period. Radial velocity measurements of the wings of Hβ and of the absorption line system of the late-type star yield semiamplitude values of K. = 101 ± 6 km s. and Kab = 151 ± 7 km s., respectively. Radial ve

https://doi.org/10.1007/978-3-030-59273-8ge outburst of SS Cyg can probably be explained using a model of a double star which is surrounded by an absorbing gaseous shell. It is noted that the existing data are not numerous enough for the explanation of the SS Cyg variability, in particular, its short-term variations..SS Cyg is a spectrosco

Anjia Wang,Xinyao Yi,Yonghong YanFrom about 30 Dwarf Novae with the best determined distances the following relationships are found..This final correlation is interpreted in terms of the disc instability model of dwarf novae and successfully predicts the observed width of outburst versus P relationship.
