Otero, Sebastian Alberto
|
Another fading event on January-May 2020 (ASAS-SN and KWS data). Not eclipses but likely dust-fading events like in other WC stars. TESS data show lots of periods (4.051, 2.918, 1.5266 an 1.1942 d., total amplitude 0.11 TESS) but not traces of the 1.75 d. ellipsoidal period reported. |

Otero, Sebastian Alberto

0.1 mag. variability at maximum. Possible eclipses (1.2 mag. duration 40 d.) at JD 2418560 (1909, Sept. 11) and 2444412 (1980, June 21) (1984PASP...96..618M). Ellipsoidal periods of 1.7556 d. in 1981A&A....96..133I or 1.75404 d. in 1986PASP...98.1170M are not confirmed by ASAS-3 data and data in 1986A&A...162..109V. |
