Features of the Interstellar Extinction Curveμm absorption bands of small silicate spheroids upon their shape and alignment has been studied. It is found that the bands can be displaced by ～ 1 μm towards longer wavelengths from their positions for corresponding spheres : and that a further, though small, displacement can be superimposed upon this by their subsequent alignment.作者: 平靜生活 時間: 2025-3-22 01:07

Correlations between .. and .. and between .. and .. are indicated..The results have been qualitatively interpreted in favour of the dust model consisting of a mixture of small silicate grains and larger silicate grains coated by molecular mantles.作者: 尊嚴(yán) 時間: 2025-3-22 06:23
Diffuse Band Extinction and Polarization in Core-Mantle Grainse only apparent possibility for producing symmetric band shapes in the dust grains is in the very small bare particles in interstellar space which, if they are aligned and produce the λ 2200 band, must exhibit a strong polarization effect in this region.作者: 外面 時間: 2025-3-22 09:11
Formation and Flow of Dust Grains in Cool Stellar Atmosphereslead to fairly large (～0.1 μ), scattering silicate grains. An instability is suggested for cool M giants and supergiants, which leads to a patchy distribution of surface temperature (grains in cool patches, high flux in warm patches).作者: 大量殺死 時間: 2025-3-22 15:42

On the Presence of Phyllosilicate Minerals in the Interstellar Grainsterstellar absorption band near 9.8 μ. Laboratory spectra of several phyllosilicates give better agreement as does the spectrum of a carbonaceous chondrite. We propose that the silicates in the interstellar grains are predominantly phyllosilicates and suggest additional spectral tests for this hypothesis.作者: 易改變 時間: 2025-3-22 21:26
Conference proceedings 1976ave been guessed only a few years ago.

Diffuse Interstellar Band Formation in Dense Clouds decreases systematically with increasing grain size. It is concluded that the diffuse bands are not formed in the mantles which accrete on the grains in interstellar clouds, but that they could be produced in the cores of grains or in some molecular species.作者: Ventricle 時間: 2025-3-23 12:47
A Review of Recent Observations of Dust in H , Regionsust be high for λ > 504 ?. This restriction is lifted if the visual extinction cross section of the grains in H . regions is less than that for grains in the general interstellar medium. New observations of the Orion Nebula indicate that the visual extinction cross section is within a factor 2 of the value in the general interstellar medium.作者: consolidate 時間: 2025-3-23 14:42

Diffuse Band Extinction and Polarization in Core-Mantle Grainsthickness. It is shown that no matter whether the source of the bands is in the silicate cores or the accreted icy mantles the polarization shapes are highly asymmetric for all mantle thicknesses. The extinction band shapes are significantly less asymmetric although the effect is clearly present. Th作者: Cardiac 時間: 2025-3-25 14:17 作者: maculated 時間: 2025-3-25 18:10

Thermal Emission Spectra of Silicates from Planetary Nebulaemed using dielectric constants of lunar silicates. The results have been compared with previous work on pure graphite and ice-mantle grains.
