    Notes: [Auszug] There is considerable evidence to support the view that silicate grains exist in circumstellar envelopes around certain cool stars1. An emission feature in the 8?12 mm waveband occurring in the spectra of many cool Mira-type stars has been identified with particles of a mineral-like composition. It ...

    Notes: [Auszug] As pointed out in my article1 dust grains distributed throughout the disk of the galaxy will scatter X-ray photons from the isotropic cosmic background as well as from discrete sources. While I agree with the comments of Mack and Webster concerning the scattering of the isotropic ...

    Notes: [Auszug] The existence of a diffuse background of optical radiation close to the galactic plane has been known for many years and is usually attributed to the scattering of starlight by interstellar grains2-4. The same grains would also scatter X-rays from a cosmic background as well as from discrete ...

    Notes: [Auszug] Models proposed for the infrared radiation of Seyferts fall into two main categories: (a) non-thermal synchrotron emission from relativistic electrons; (b) thermal emission from dust grains surrounding a central ultraviolet source. Although synchrotron models have been more widely discussed, it has ...

    Notes: [Auszug] The maintenance of kinetic temperatures ~ 100 K has posed a problem recently because of the relatively high efficiency of the cooling mechanisms which are believed to operate in interstellar conditions at temperatures less than a few hundred degrees Kelvin1-4. Cooling occurs chiefly through ...
