Unusual shell star [P.W.Merrill, C.G.Burwell, ApJ 110, 387, 1949.]. Similar to EW Lac. He lines are widened by the rotation, NaI lines are narrow. Light changes are periodic: Min = 2436458.66 + 0.8518d*E. The cause of variations is probably connected with the rotation and the inhomogeneous brightness distribution over the disk of the star [C.R.Lynds, ApJ 131, 390, 1960.]. Profiles of spectral lines vary. The expansion of the envelope terminated in 1965, which apparently led to the development of inhomogeneities and to the broadening of hydrogen line profiles [N.F.Vojkhanskaya, IAU Symp N70, 327, 1976.]. |
