Scientific paper

We present the catalog of 112 massive isolated white dwarfs, both magnetic and nonmagnetic, with masses M ≥ 0.8 M&sun;}. Mass determinations and other parameters of the white dwarfs were taken from the literature available. For each star we present averaged values of mass, effective temperature, logarithm of surface gravity log g, radius, distance, and the surface magnetic field for magnetic white dwarfs. Mass distribution of massive magnetic white dwarfs is flat, whereas nonmagnetic WDs exhibit steeper mass distribution towards the highest masses. We note that all four most massive stars with masses M ≥ 1.3 M&sun; are magnetic white dwarfs. We also conclude that the secondary maximum at 1.04 M&sun;, clearly seen at the mass distribution of all white dwarfs from our sample, is caused exclusively by nonmagnetic white dwarfs.
