Otero, Sebastian Alberto
|
J-K= 0.86. A lot of periods between 40 and 90 days (51, 54, 63, 73 d.) and a long-term mean magnitude change of approximately 3300 d. RVB-like behaviour but no regular period for the short term variations.
ASAS-3 magnitudes contaminated by several nearby stars, specially GSC 06856-02058 (V= 13.5; sep.9"). Range has been corrected. |
