Hα-emission stars in and near NGC 7000
Abstract
A region in Cygnus comprising NGC 7000 and IC 5070 was searched for Hoc-emission stars on objective-prism plates obtained with the Uppsala-Kvistaberg Schmidt telescope. Altogether 141 stars of this category were found, 35 of which were previously known. For various reasons several of the previously known Hoc-emission stars in the region escaped detection on this occasion. In the catalogne are listed positions (1950.0), V and B magnitudes, Hoc intensities and, where known, spectral types. Stars of special interest are discussed in the text. Key words: Hoc-emission stars-NGC 70()()diffuse nebulae.
