Download synthetic colors and evolutionary sequences for hydrogen- and helium-atmosphere white dwarfs from Pierre Bergeron's website. This resource provides photometric data across multiple filter systems (SDSS, Gaia, 2MASS, Pan-STARRS, etc.) and theoretical cooling tracks for various white dwarf masses.
Fill in the fields to get the corresponding white dwarf properties and diffusion timescales.

** Buchan et al. (2025). Specifically, the diffusion timescales provided here are those from the so-called SV grid, which includes convective overshoot following a 1D parameterization where the extent of the overshoot region varies with effective temperature. See Section 4.2 of the paper for details.
