Far infrared observations of S 255 and S 187.
Abstract
Large scale far infrared observations of the S255 and S187 molecular clouds have been made at 150 μm and 85 μm with an angular resolution of 4'S. The total luminosity of S255 is at least 1.71 105 Lsun and is sufficient to maintain the gas at its observed temperatures where the density is of order 104 cm-3. S 187 has a total luminosity of 3.2 104 Lsun, presumably due to two B0 - B0.5 stars, one the deeply embedded exciting star of the visible nebula, the other identifiable with the ultracompact H:: region S187A.
