[mesa-users] Custom Irradiation

[etheridge d.j. (dje1g11)]

Thank you both for your help, I've managed to get the other_wind hook working with the null template in the binary_donor_only test suite. I've started my own routine using the null template, but how do I get access to variables like the donor stars radius and the binary separation?

I see you can use

    type (star_info), pointer :: s

to get access to things like the model_number, and similarly

    type (binary_info), pointer :: b

What is contained within star_info and binary_info ?


Thanks,

Dan

For the case of a system that is undergoing RLOF, the stellar wind is considered together with the mass transfer. This means that the star will be losing mass at the given rate taking away the specific angular momentum of its orbit, and on top of this MESA will compute a mass transfer rate according to whatever prescription is being used.

So, using other_wind should work, barring as Bill says violent variations that could make convergence difficult.

Cheers!

HI --- just to be clear, my previous answer was for the non-binary case in the sense that the mass loss isn't being caused by Roche Lobe overflow but is instead caused by extreme irradiation from the companion.  this would be applicable in a binary system that is out of contact.

if you have a case that is actually in contact, then we'll have to see what Pablo has to offer.

Hi,

I'm aware that the binary module in MESA can be customised using run_star_extras.f. How could I implement a different prescription for the mass lost from a donor star due to pulsar irradiation? I would be using equation 3 from Stevens et al. 1992, MNRAS, 254, 19P.
Any help would be greatly appreciated.

Many thanks,

Daniel Etheridge
