inertial and co-rotating frames
Posted: Wed Oct 31, 2018 4:33 pm
Hi everyone!
I'm trying to include rotation in the modeling of a MS star, but I'm having troubles understanding gyre output. I hope to find help here!
I'm sending the gyre input file 'gyre.in' in which I included a rotation of omega_rot=1.01248 UHZ and I used the co-rotating frame for the freq_frame and grid_frame.
My problems are that I cannot find any symmetry in the modes and gyre gives, for instance, 5 modes with l=2 and m=1 and 8 modes with l=2 and m=-2 , being 4 with l=2 and m=0...even when I correct the frequencies with:
freq_correct=Re(freq)-m*omega_rot ; which I understand it gives the frequencies in the inertial frame.
Could you please, let me know what I'm doing wrong?
Thank you very much!!
Cheers,
Julieta
