Presupernova models - 2025 grid (Limongi et al. 2025, ApJS, 279, 41)

Content of this directory ("Presupernova Models")

Structure and chemical composition of the presupernova models for the following grid:

Initial Masses (Solar Masses)     : 9.22, 10, 11, 12, 13, 15
Initial Metallicity [Fe/H]        : 0
Initial Rotation Velocity (km/s)  : 0 (non rotating)

Files are named according to their initial mass, metallicity and initial rotational velocity, i.e.:

                      "mmmmzvvv.pub"

mmmm = initial mass in units of 0.01 Msun (i.e. '0922' means 9.22 Msun, '1000' means 10 Msun, '1500' means 15 Msun)
z    = initial metallicity ('a' = [Fe/H] = 0)
vvv  = initial equatorial rotational velocity in km/s ('000' = non rotating)

Format of the files

Each file is a plain ASCII table. The first row contains the column labels, each of the
following rows refers to one zone of the presupernova model, from the center (zone 1)
to the surface (last zone). There are 352 columns:
15 physical quantities followed by 337 columns with the chemical composition.

Physical quantities (columns 1-15)

Zone       =  zone number (1 = innermost zone)
M          =  mass coordinate in solar masses (msun = 1.989d33 g)
R          =  radius in solar radii (rsun = 6.951e10 cm)
P          =  log pressure (dyn cm^-2)
T          =  log temperature (K)
Rho        =  log density (g cm^-3)
Ye         =  electron fraction
PSI        =  degeneracy parameter
S/NAK      =  entropy per baryon in units of the Boltzmann constant (S/(N_A k))
GAMMA      =  adiabatic index
FP         =  correction factor due to rotation (eq. 10 in Endal & Sofia, ApJ, 210, 184, 1976)
FT         =  correction factor due to rotation (eq. 16 in Endal & Sofia, ApJ, 210, 184, 1976)
OMEGA      =  angular velocity (s^-1)
OMEGA-C    =  breakup angular velocity (s^-1)
OM/OM-C    =  omega/omega-breakup
J-SPEC     =  specific angular momentum (cm^2 s^-1)

Note: the models are non rotating, therefore FP = FT = 1 and OMEGA, OMEGA-C, OM/OM-C and
J-SPEC are identically zero.

Chemical composition (columns 16-352)

The remaining columns give the abundance, in mass fraction, of each species, from H to Bi09,
as labelled in the first row (element symbol followed by the mass number). In each zone
the sum of all the columns is 1. In particular:

H, H2, H3, He3, He4, Li6, ... = hydrogen, deuterium, tritium, 3He, 4He, 6Li, ...
Alg6, Alm6                    = ground state and isomeric (metastable) state of 26Al
N                             = free neutrons (last column)
