[mesa-users] Weird jumps in radius for rotating 8.1Msun model

[Hideyuki Saio]

Hi

I have encountered similar jumps in radius several times at non-rotating massive star evolutions. They are mostly very small, and seem to be caused by  infusions of H-rich matter into the convective core. I attach a plot for a relatively large jump  (Yc means helium abundance in the core).  FYI. 

Cheers,
H.
