[Mesa-users] Models failing to reach core collapse

[Taylor Jacovich]

Hello all,

	Have run into an issue with the current version of MESA where stars with a specific mass will never reach core-collapse (fe_core_infall > 10**3km/s stopping condition).  A full description of the issue and all the model data can be found here: https://gitlab.com/wind-loss-testing/readme <https://gitlab.com/wind-loss-testing/readme> .

	The reader’s digest version is that stars with a certain mass (eg. 15.0Msun) will get stuck at a sub-Chandrasekhar mass iron core and happily coast for weeks at a time.  Meanwhile masses directly around the ones that fail to collapse (eg. 14.9Msun and 15.1Msun) will collapse without fail.  We are using Farmer’s inlists that were designed to help with explodability, and the only parameter we change between runs is the mass. 
	
	Any suggestions on new parameters to try or other options that may relieve the issue are much appreciated. Inlists are attached below, or you can clone from this directory https://gitlab.com/wind-loss-testing/windloss-template <https://gitlab.com/wind-loss-testing/windloss-template> to have an identical experience.

Thank you,


Taylor Jacovich
