Here you can find YREC solar models with frequencies calculated with the Porto Oscillation Code (POSC).
The list of data available (models and frequencies) is given below:
The input parameters used to produce the models and the model data are listed here:
| MODEL | M/Msun | Y0 | Z/X0 | AGE [Gyr] | α (MLT) | LOG(L/Lsun) | LOG(R/Rsun) | Models | Frequencies |
| A | 1.0 | 0.2686 | 0.02811 | 4.57 | 2.143 | < 2.0 × 10-5 | < 3.0 × 10-5 | Data | Data |
| B | 1.0 | 0.2686 | 0.02811 | 4.57 | 1.831 | < 1.0 × 10-6 | < 1.0 × 10-6 | Data | Data |
| C | 1.0 | 0.2710 | 0.02821 | 4.57 | 1.962 | < 2.0 × 10-6 | < 1.0 × 10-6 | Data | Data |
The model parameters of the callibrated solar models are listed here:
| MODEL | Teff [K] | LOG(G) | Ys | Z/Xs | Rcz/Rsun | Mcc/Msun | LOG(Pc) | LOG(Tc) | LOG(ρc) | Shells |
| A | 5779.6 | 4.4378 | 0.2407 | 0.02312 | 0.7139 | 0.0 | 17.373 | 7.1952 | 2.1802 | 1918 |
| B | 5779.7 | 4.4378 | 0.2407 | 0.02312 | 0.7140 | 0.0 | 17.373 | 7.1952 | 2.1801 | 1918 |
| C | 5779.6 | 4.4378 | 0.2710 | 0.02821 | 0.7246 | 0.0 | 17.367 | 7.1924 | 2.1717 | 1921 |
The physical assumptions used to produce the models are listed here:
| MODEL | Mixture | Diffusion/ settling | Opacities | EoS | Reaction rates | Overshoot | Atmosphere |
| A | GN93 (1) | X + Y | OPAL (2) | OPAL (3) | Bahcall (4) | - none - | Krishna-Swamy (gray) |
| B | GN93 (1) | X + Y | OPAL (2) | OPAL (3) | Bahcall (4) | - none - | Eddington (gray) |
| C | GN93 (1) | - none - | OPAL (2) | OPAL (3) | Bahcall (4) | - none - | Krishna-Swamy (gray) |
