Re: possible to model observed non-monotonic rotation profile?
Hi Rich et al., Quick question: is it possible to hand GYRE, or build within GYRE, initial conditions that have a non-monotonic rotation profile (e.g. a measured surface rotation rate than exceeds an internal subsurface rotation rate)? My assumption is no (and how would one produce that in MESA, an...

Re: Lower asymptotic period spacing than expected
I would advise against modifying any code -- post-processing is the right way to go.

Re: Lower asymptotic period spacing than expected
Hi Rich, I returned to this problem because I find this behaviour in other calculations. Again I found Deltag values quite lower than expected. So I write the N on the MESA file and proceed to compute "by hand" the intergral to obtain the value of the asimptotic period spacing with the Tassoul form...

Re: Lower asymptotic period spacing than expected
OK, thanks for checking that out!
But I still think this behavior is physical -- see, e.g., Miglio et al. (2008, MNRAS, 386, 1487), especially their Fig. 4.

Rich

Re: Lower asymptotic period spacing than expected
Hi Francisco -- At first, I thought there may be an issue with your input file -- but that looks fine. On further consideration, I think the result you are finding for the period spaceings looks correct. Your model star shows a period spacing with regular dips -- this is the symptom of mixed modes, ...

Re: Lower asymptotic period spacing than expected
Hi Francisco --
Welcome to the forum! As a first suggestion, can you post the namelist input file you use for GYRE?
cheers,
Rich

Re: GYRE 6.0 libgomp issues?
yup that worked, thanks! I do note that eta is listed as a valid output option at https://gyre.readthedocs.io/en/stable/ref-guide/output-files/summary-files.html#only-n without warning that this is a nad parameter only, but perhaps a more informed user/real asteroseismologist would recognize that t...

Re: GYRE 6.0 libgomp issues?
Thanks. It appears the crash arises from requesting 'eta' as one of the adiabatic summary-file items -- for adiabatic calculations, this quantity (the Stellingwerf normalized growth rate) is undefined. So, as a workaround, remove 'eta' from the summary_item_list in &ad_output. I'll also be working o...

Re: GYRE 6.0 libgomp issues?
Hi Meridith --
The input file you sent me still has a number of template fields -- e.g., <<freq_min>>. Can you send an example with these filled in (pref. the crashing example).
cheers,
Rich

Re: {M,R,L}_star reported for every mode in summary
Hi Warrick --
This is in fact a design choice; although GYRE currently only works with a single stellar model at a time, the output code can support multiple models. Hence, I decided it made more sense to have {M,R,L} be arrays.
cheers,
Rich
