MESA File Format

Files in MESA format store ASCII text data describing a MESA stellar model. Note that MESA itself refers to these files as ‘GYRE-format’ files; to create one of these files in MESA, set the pulse_data_format parameter of the &controls namelist group to the value GYRE.

There are a number of versions of the MESA format, distinguished by the initial header line:

• Version 0.01
• Version 0.19
• Version 1.00
• Version 1.01
