摘要
摘要:研究了位于白矮星WD0245+541西北方向0.15°的100m红外天文卫星(IRAS)地图上一个17.4' x 8.6 '大小的新远红外尘埃空洞。我们给出了尘埃色温，尘埃质量，以及空腔内和周围的普朗克函数分布(FIC0248+542)。尘埃色温在23.0到27.3(±1.9)K之间，尘埃质量为0.8 x 1026 kg。普朗克函数沿白矮星的分布是不均匀的。关键词:白矮星，远红外空腔，尘埃色温，普朗克函数，高斯分布
A New Far Infrared Cavity Near White Dwarf WD0245+541
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.
