| Abstract: |
We have used starspot migration models to obtain constraints on the co-latitude of a
moving dark region on the surface of a contact binary system. Our study focused on
two migration indicators: the evolution of the O‘Connell effect, and changes in
the brightness of the maxima. The amplitude and shape of these signals obtained
observationally were confronted with simulations, giving
rather sharp boundaries for the allowed co-latitude of the migrating starspots.
Our models prefer large, polar or circumpolar migrating starspots. This
may explain how the long-lived migrating spots survive
the journey in latitude around the neck of the contact binary. |
