Scientific paper

IR photometric observations have been made for 10 white dwarfs. These data have been combined with published infrared photometry, visible and ultraviolet data, to derive effective temperatures and angular diameters for 29 white dwarfs using the IR flux method. Radii are determined for 25 stars, and masses are derived using the Hamada-Salpeter mass-radius relation for degenerate stellar cores. With better IR photometry this method is capable of giving very accurate values of effective temperature, radius, and mass for stars with effective temperatures less than 8000 K.
