It was investigated only by low-resolution studies of the whole cloud complex (e.g. Gatley et al. 1979; Wilson et al. 1979).的染料 发表于 2025-3-25 11:33:50

Creating and Playing Flash Video,6 IR and Cep A East. Excitation temperatures and masses were derived from the low-lying pure rotational levels of H2 and are 490 and 740 K and 0.04 and 0.007 M⊙ for S106 and Cep A, respectively. The observations were compared to theoretical models for PDRs and dissociative and non-dissociative shockGlossy 发表于 2025-3-25 18:15:41

Whereas some objects still show interstellar ice features, the most evolved objects are coincident with ultracompact HII regions and show strong emission lines from atomic species and polycyclic aromatic hydroc载货清单 发表于 2025-3-26 01:48:03

The dust is understood to represent debris related to planet formation, and the known disk systems may be dense analogs of the Kuiper Belt structure in our outer solar system. ISO observing programs plan to address questions regarding how common planetary material is around normal st神圣不可 发表于 2025-3-26 04:33:22
Going Small and Going Big with Flash Video,e usually skips when thinking about stellar evolution. In early and in late stages of evolution, stars interact much more intensely with their environment. It is this interaction and the circumstellar material involved rather than the star itself which makes them an interesting subject of infrared adecode 发表于 2025-3-26 09:14:31
