[mesa-users] White Dwarf Mass Gain

[Eric Blaney]

Dear Mesa-Users,

I have recently been attempting to use MESA to model accreted mass onto a White 
Dwarf until it reaches it's chandresekar mass limit.  I'm simply wondering if it 
is even possible, or if anyone has done this before using MESA and would share 
any tips on how to successfully do so. 


When I add mass onto White Dwarfs, it seems that that star becomes unstable once 
hydrogen burning begins--reducing the timestep to mere minutes and the mass gain 
rate jumps back and forth from, my normal input value, 10^-8 SolarMass/yr and 
10^-99.  If anyone has any idea how to fix these problems, if there even is a 
solution, it would be greatly appreciated.

Much thanks,

Eric
