Help define the type of variability.

Sun, 01/21/2018 - 18:00

I found a very interesting eclipsing system. I am at a loss to define the type of variability. Maybe the type EA/RS and possibly signs of accretion.

See attached phase plot.

Catalog data
2MASS J= 10.58, K= 9.78, J-K= 0.8
GALEX-DR5 NUV= 19.83
AllWISE W1= 9.64, W2= 9.69, W3= 9.63, W4= 8.65, W1-W2= -0.05, W3-W4= 0.98
APASS-DR9 B= 14.43, V= 13.09, B-V= 1.34

Help define the type of variability.

Another interesting system. The star has a type of EW variability with a period of 1.21242 and two periods are superimposed with a smaller amplitude characteristic of the GDOR: P1= 0.37703 d, P2= 1.5457. Is it possible to specify the type of variability EW+GDOR?
