[mesa-users] Fundamental Modes from ADIPLS/MESA

Hi Bill,

In case you're still in search of an answer...

If you've had MESA output FGONG files (see star_defaults.dek entry write_pulse_info_with_profile and related info), then it is fairly straightforward to run ADIPLS on the FGONG output (also, be sure you have set "calculate_Brunt_N2 = .true." in your &controls inlist). I haven't yet run ADIPLS as an integrated step in MESA, although my understanding is that may be under development. 

As far as I know, the current ADIPLS integration with MESA is for matching to a set of observed oscillation frequencies from asteroseismic observations (which is not something I, myself, do). You can see the controls for this in mesa/astero/test/inlist_oscillation_controls, but I can't claim to have a much better understanding of what's going on there than you. 

To just use ADIPLS for calculating a few modes, you can try the following:
First, make sure that ADIPLS has been compiled and the binaries are in your path (if you're not sure, follow the instructions in mesa/adipls/readme_ADIPLS_standard). You will need to use the ADIPLS routines to convert the FGONG to and AMDL model file, write an inlist file (like that in mesa/adipls/test/adipls.c.in), and then run adipls.n.d with the inlist file as input, from the command line. This will compute the modes based on the input variables you specify in your adipls inlist. The meanings of the different variables in the inlist are pretty well described in mesa/adipls/adipack.c/notes/operation.pdf.


P.S. I'm running MESA 3851.

> Hello MESA gurus!
> I'm trying to find the fundamental oscillation modes for stars in the instability strip, but I'm having trouble making sense of what's going on in the adipls, astero, or pulse directories. I see that there is an astero pre-made model in the test suite, but again, I'm not quite sure what's going on there.
> I currently have several models saved that are parked in the instability strip. Is there a straightforward way to get the modes from these saved models?
