## File Syntax and Content

Files are named m[M]z[Z][A], where
• M is the star's initial mass (in solar units),
• Z is the star's initial metallicity (in mass fraction) and
• A is an additional character specifying a particular feature of the computed model (optional).
Four files are available for each stellar model, namely
• file.hrd : HRD information
• model : model number,
• phase : phase number (1 for PMS, 2 for MS, 3 for Post-MS, ...),
• L : surface luminosity (in solar units),
• Mbol : corresponding bolometric absolute magnitude,
• Reff: radius at photosphere (in solar units),
• R* : stellar radius at optical depth = 0.005 (R, in solar units),
• Teff : temperature at $\tau =$ 2/3. This is actually slightly different from the effective temperature defined as $T_\mathrm{eff} = (L/(4\pi \sigma R²)^{1/4}$ (in K),
• rho_eff : photospheric density (in cgs),
• log g : surface gravity (in log10 of cgs),
• M : total mass (M, in solar units) and
• age : age (in yr).
• file.var1 : internal structure
• model : model number,
• Tc : central temperature (in K),
• rhoc : central volumic mass (in cgs),
• etac : central degeneracy parameter value,
• M_core : mass coordinate of the central burning core (in solar units),
• R_core : radius coordinate of the central burning core (relative to the total radius),
• Lnuc : contribution of nuclear energy production to the total luminosity (relative to the surface luminosity),
• Lgrav : contribution of $\epsilon$(grav) to the total luminosity (relative to the surface luminosity),
• k2_conv : moment of inertia of the convective envelope (in units of total M*R**2),
• k2_rad : moment of inertia of the central radiative core (in units of total M*R**2).
• file.var2 : convection
• model : model number,
• Mconv1 : mass coordinate of the top of the convective core (in solar units),
• Rconv1 : radius at the top of the convective core (normalized to the total radius),
• Menv_bot : mass coordinate of the bottom of the convective envelope (in solar units),
0 means fully convective star and no convective core
• Renv_bot : radius of the bottom of the convective envelope (normalized to the total radius),
0 means fully convective star and no convective core
• Tenv_bot : temperature at the bottom of the convective envelope (in log10 of K),
• rho_bot : volumic mass at the bottom of the convective envelope (in log10 of cgs).
• file.xsurf : surface abundances
• model : model number,
• X(2H) : surface mass fraction of 2H,
• X(3He) : surface mass fraction of 3He,
• X(6Li) : surface mass fraction of 6Li,
• X(7Li) : surface mass fraction of 7Li,
• X(9Be) : surface mass fraction of 9Be,
• X(10B) : surface mass fraction of 10B,
• X(11B) : surface mass fraction of 11B.
