How to fit with a heating dominant binary in compact binary

[tpos8]

I want to fit the light curve in a compact and a stellar system, only one peak and one trough. But the fit flux show a double peak structure, so that, how should I set those parameters to fit it.

force and fit are not intended to be passed and will override the behavior of constraints and may result in an unphysical system. So my first suggestion would be to remove those and flip constraints as necessary. Once you have a physical system, plot an animation of the mesh colored by intensity which should help to show why the light curve looks the way it does - my guess is that a combination of irradiation and gravity brightening are the cause of the signal you are seeing in the synthetic model.

Hope this helps!

We fitted the light curve as linear, but the companion's irradiated face is facing us, not the compact object. How can we fix this?

Are you still using force=True anywhere in your script? If so, please remove those and rerun from the top, as they can result in unphysical parameters. It's too hard to tell what is going on here from the screenshots, we can try to reproduce if you can attach a minimal script to reproduce or a copy of the bundle itself.
