Selected stages for carbon - oxygen white dwarf (WD) models with and without a hydrogen envelope and with stellar masses from 0.45 to 1.2 solar masses. Each file refers to a specific evolutionary sequence characterized by a given stellar mass, hydrogen envelope and metallicity Z: For instance, t09_1e6.z3 stands for 0.9 (solar masses) WD models with an outer hydrogen envelope having a fractional mass of M_h/M_* = 10^(-6). Z3 means a metallicity Z=0.001. t11_e10.z3 stands for 1.1 (solar masses) WD models with an outer hydrogen envelope having a fractional mass of M_h/M_* = 10^(-10). Calculations were made in the framework of the Canuto, Goldman and Mazzitelli theory of convection. For each file, we list from left to right: log_10 of photon luminosity (in solar units), log_10 of effective temperature (K), log_10 of central temperature (in 1E6 K), log_10 of central density (cgs units), crytallized mass fraction, log_10 of age (in 1E6 years), log_10 of stellar radius (in cm), log_10 of surface gravity (cgs units), surface hydrogen abundance (X_h), and the log_10 of hydrogen burning luminosity (in solar units) when it is not negigible.

For models without hydrogen envelope (...e00.z3) we list from left to right: log_10 of photon luminosity (in solar units), log_10 of effective temperature (K), log_10 of central temperature (in 1E6 K), log_10 of central density (cgs units), crytallized mass fraction, log_10 of age (in 1E6 years), stellar mass (in solar units) and log_10 of surface gravity (cgs units).

Note: The age values corresponding to the early stages of evolution are strongly affected by the procedure we employed to obtain the initial models. For more details, see Althaus & Benvenuto, 1998, MNRAS, 296,206. For new evolutionary calculations for DA white dwarfs with Z=0.01 and Z=0.001 computed by our group and that consider the full evolution of progenitor stars as well as a updated microphysics are available at: New DA cooling sequences
