0067-0057 st grains and molecules properly, 5 especially in stars with truly large mass loss rates, ~ 10- M9/yr, one requires IR and radio astronomy. As this stage of copious mass loss only lasts for ~105 years one might be tempted to ask, "who cares?".978-94-010-8896-1978-94-009-5428-1Series ISSN 0067-0057 Series E-ISSN 2214-7985Living-Will 发表于 2025-3-23 19:43:34
Circumstellar Dynamics Observed by Infrared Heterodyne Spectroscopy,avior. The answer to this question may help us understand how mass-loss is initiated in stars prior to the formation of dust-grain condensates. Observations of CO absorption lines in the infrared by Hall (1980) indicate that in o-Ceti the circumstellar gas is grouped into several velocity components. Jura (1984) has . of the circumstellar material.贫困 发表于 2025-3-23 23:50:06
used to prepare new copolymers. Methylenecycloalkanes are polymerized by transition metal complexes to produce polymers via addition polymerization or ring-opening polymerization. Copolymerization of dienes with CO is promoted by late transition metal complexes to give polyketones with vinyl groupscompose 发表于 2025-3-24 05:43:06
