Abstract
Abstract: A new far infrared dusty cavity of size 17.4' x 8.6’ at 100 m IRAS (Infrared Astronomical Satellite) map located 0.15o northwest of white dwarf WD0245+541 is investigated. We present dust color temperature, dust mass, and the Planck function distributions in and around the cavity (FIC0248+542). The dust color temperature has been determined to fall within the range of 23.0 to 27.3 (±1.9) K, while the dust mass is found to be 0.8 x 1026 kg. The Planck function distribution along the white dwarf is observed to be non-uniform. Keywords: White Dwarf, Far infrared cavity, Dust color temperature, Planck function, Gaussian distribution.
