Abstract: | This paper presents an analysis of a series of spectra in the Red Rectangle nebula. Only the reddest part of the spectra can
safely be attributed to light from the nebula, and indicates Rayleigh scattering by the gas, in conformity with the large
angles of scattering involved and the proximity of the star. In the blue, light from HD 44179, refracted or scattered in the
atmosphere, dominates the spectra. This paper questions the reliability of ground-based broad-band spectra of extended objects
in the blue. |
