Basic Parameters











Model star 2 as a point mass?

Mass Transfer Parameters









Binary Interaction Parameters







Simulation Resolution Controls







Stopping Conditions

If none of these fields are filled out, MESA has built-in stopping conditions corresponding to unphysical changes or computationally strenuous next steps that will stop the simulation.







Maximum simulation age: e



Output Data

Please keep in mind when selecting output parameters that adding more will increase the file size and download time; this can add up faster than expected.
