Otero, Sebastian Alberto
|
In 1999 NSVS data shows an RVA-like light curve with P= 120 d. (60 d. for the SRD solution).
Between 2003 and 2009 ASAS data shows a single wave variation of 108.5 d. and sometimes alternating minima depth with P= 217 d.
The SRD solution based on the ASAS-3 more recent period is given. J-K= 1.10. |
