Abstract:	White dwarf (WD) populations are analyzed using Bayesian tools, which allows inferring possible evolutionary paths through the study of the mass values. We employed a sample of 2761 DA white dwarf stars from the SDSS, and obtained the central mass values and their corresponding standard deviations using a bimodal population as an ansatz. The results indicate a population with M1 = 0.60 M☉ and σ1 = 0.06 M☉, corresponding to a single stellar evolution, and a second population with M2 = 1.00 M☉ and σ1 = 0.11 M☉ possibly due to binary evolution resulting from mergers.
