... In this model the stars lie above and below the layer of the gas and dust. ... These regions are in turn tracers of gas and dust in the galaxy. ... The dust lanes can be used to trace shocks in the gas flow (Athanassoula 1992) which ...
... Colors of SNe Ia provide a way to correct for extinction by dust in both our Galaxy and the host. ... blue color of the host may indicate a population of young stars, and there is a corresponding possibility of dust extinction ...
... The radius of the 23.5 mag arcsec~2 isophote (R ) is measured directly from the photometric proпles 23.5 and, therefore, is also corrected for dust extinction (assuming the dust acts uniformly over the disk) and projection eects. ...
... Zodiacal light. Sunlight reflecting off dust grains in the inner solar system. Concentrated towards the ecliptic. ... to things blocking the light in front of the CCD, such as dust grains on the dewer window, and features in the telescope optics ...
... The dust lanes indicate the location of shocks, as discussed above and in Paper I. The position of the dust lanes favors fairly fast rotating bars ; in slow bars the shocks move too far ahead of the bar, as seen in the simulations presented here and the ...
... explored the 27 RSAA Annual Report 2001 occurrence of dust in Mira atmospheres and its effect on the brightness distribution across the observed stellar disk (limb darkening) under schematic assumptions about dust temperatures and dust particle properties ...
