Otero, Sebastian Alberto
|
It evolved in one century from a normal RCB to a hot RCB and currently to a extreme Helium star with no deep minima since 1934 (2016MNRAS.460.1233S). Currently mean V mag. is V= 13.4 (2018). |

All spectral lines are very weak. No IR excess. The photometric behaviour outside major Min is described in [F.M.Bateson, NZAS Publ N6 (C 78), 39, 1978.]. |
