Re: Only g modes calculated i red giant star
Hello Warrick, thank you very much for your answere. I have used the scaling relations from the paper Kjeldsen & Bedding (1995) with the radius and effective temperature of my stellar model which leads to much better results. I could now find both p and g modes, because I now know in which frequency...

Re: Only g modes calculated i red giant star
Hello Warrick, regarding the v_max I refer to the paper "Models of red giants in the CoRoT asteroseismology fields combining asteroseismic and spectroscopic constraints" (link: https://arxiv.org/pdf/1505.01529.pdf). On page 3 there is a tabular containing information about red giants like v_max, the...

Only g modes calculated i red giant star
Hey everybody, I have recently started calculating oscillation frequencies of red giant stars with gyre. For this I proceeded as follows: I used a stellar model (which I obtained from Mesa) for a red giant with a mass of 0.6*Msun. For the frequency scan I used freq_min = 3 microhertz and freq_max = ...

Re: Convergence Problem for RGB Model
Hi Warrick, thank you very much for the answere. I will try the approach of adjusting the range of the frequencies. I have a further (more general) question concerning the computation of the oscillation frequencies of red giants. So far I have used the RGB model for red giant calculations. My goal i...

Convergence Problem for RGB Model
Hello everybody, I'm an undergraduate student in physics from Germany and I have recently started using Mesa and Gyre to model stellar evolutions and to compute oscillations frequencies that take place in stars. For this I followed the instructions given at the Gyre Wiki by Richard Townsend ("Gettin...
