High Spatial Resolution Infrared Observations of Evolved Starsof their energy. They are visible at great distances in the galactic plane in spite of the effects of interstellar reddening. Many are losing mass at prodigous rates, generating thick, dusty shells of temperatures less than about 1000K. The infrared is an obvious choice for the study of photospheric and circumstellar problems alike.作者: 淡紫色花 時(shí)間: 2025-3-22 13:42

A Study of Dust Condensation Around M Mira Variables Based on IRAS LRS Observationshat the silicate dust has temperatures in the range 200-500 K at the inner boundary of the silicate dust shell and that the appearance or absence of the 9.7 μm silicate feature depends on the magnitude of the inner dust shell temperature. Possible explanations of these results are discussed in terms of the physics of the condensation process.作者: Frenetic 時(shí)間: 2025-3-23 18:28
