Scientific paper

The molecular cloud B35 has puzzled observers because it contains gas which is at Tg ≍ 23K, hotter than the surrounding dust whose Td ≍ 10K. An investigation of the IRAS data, however, shows a previously unreported dust component at Td ≍ 33K whose luminosity is ample to heat the gas. IRAS also finds that about 12% of the total luminosity around the core, and about 20% along the rim, arises from the small grain component with T ≤ 300K. The temperatures of these two components vary across the source, and this behavior is discussed.
