Carbon Star Reddenings and Low Latitude H I Column Densities
Abstract
Foreground H I column densities are computed toward 564 low latitude northern and southern hemisphere carbon stars, using photometric distances and an assumed rotation curve. Separate dust-to-H I ratios and dereddened (J-H, H-K) loci are obtained for the two hemispheres. A small but statistically significant difference is found between the two samples, which is attributed to a small difference in photometric systems.
