[Mesa-users] jdot_scale warning - direct impact mass transfer in AM CVn binary

[James Munday]

Hello everyone,

I'm trying to model an AM CVn system where mass is expected to be
transferred directly onto the surface of the accretor without forming an
accretion disc, the system having a <10min orbital period, modelling in
MESA as a He WD donor and a point mass accretor. I've tried running systems
where this event would occur, where they do evolve to be an AM CVn, but I
always get a warning "check jdot_scale   1   number   number" for every
model attempt.

Does anybody know why this is or why the warning is being flagged? There
isn't any mention of jdot_scale in the docs anywhere (besides for magnetic
braking, which is not enabled).

Many thanks in advance,
James
