Hi Morgan --

It looks like the attachments didn't all come through. Can you mail them to me separately?

cheers,

Rich

Hi Morgan --

Could you post the model and gyre inlist files, so I can have a dig into this myself?

Many thanks,

Rich

Hello, I am having trouble with some inconsistency between the sign of Im(omega) and the growth rates gyre is reporting. I ran a suite of 13 WD models, and there is a spread in the sign of Im(omega) for a g-mode of radial order 2 (g2); some are positive and some are negative. However, the growth ra...

Yes, that's right -- assuming the Brunt is also in rad/s.

Hi Anwesha -- Thanks for your questions! mode period = 2*pi/sigma (from documentation) --> so here sigma is the angular frequency having unit (1/rad) In fact, the unit of sigma is rad/second (since sigma = 2*pi/period). That's sometimes also written as 1/second, since radians are unitless. now the o...

Hi folks -- I'm pleased to announce the release of GYRE 7.0, which offers a new frontend program (gyre_tides) for calculating tidal responses. gyre_tides is described in the accompanying instrument paper Sun, Townsend & Guo (2023) . Source code: https://codeload.github.com/rhdtownsend/gyre/tar.gz/v7...

Hi Warrick -- Quoting from Section 3.8.6 of Asteroseismolog (Aerts, JCD & Kurtz): In rapidly rotating stars terms quadratic and of higher order in Ω can no longer be ignored. This also includes the distortion of the star by rotation (see Section 3.2.4.2). For moderate rotation a perturbation expansi...

Hi Tao -- It looks as though the re-gridding algorithm is running into trouble for the l=1, m=1 modes -- GYRE is trying to create a grid with 91,398,783 points, which likely triggers the code to crash from lack of memory. My guess is that the problem arises because of your chosen frequency range: &s...

(realize I never answered this). This, ultimately, is due to the new gcc 12 compiler that ships with the SDK for MacOS on ARM (M1) processors. The compiler breaks bit-for-bit compatibility with previous compilers, hence the errors. Importantly, however, they are reproducible and nothing to worry abo...

Not that it is allowable for two points to have the same radial coordinate -- just not three or more! When two points have the same radial coordinate, they are treated as a "double point" where there can be a discontinuity in variables such as density. GYRE handles such discontinuities by using appr...
