Abstract. The "Catalogue of Stars in the Northern Milky Way Having H-alpha in Emission" appears in Abhandlungen aus der Hamburger Sternwarte, Band XI in the year 1997. It contains 4174 stars, range 32• having the Hα line in emission. HBH stars and stars of further 99 lists taken from the literature till the end of 1994 were included in the catalogue. We give the cross-identification of stars from all lists used. The catalogue is also available in the Centre de Données, Strasbourg 1 and at the Hamburg Observatory via internet.
Abstract. This paper is dealing with the investigation of H-alpha emission stars towards the galactic bulge. In this important region 533 H-alpha emission stars have already been discovered. We add 98 new and 9 possible new (perhaps identical with known objects) H-alpha emission stars found in the objective-prism survey of planetary nebulae and we give the identification charts, the accurate coordinates as well as a rough description. The distribution in l, b of all objects shows the expected concentration towards the galactic equator with the maximum near l=0• and b=0• distorted probably due to strong interstellar extinction.
Abstract. This paper is dealing with the discovery of 11 new or new suspected variables, found as a by-product during the preparation of our Catalogue of Stars in the Northern Milky Way Having H-alpha in Emission. We give: (1) The coordinates of the variables and of the respective comparison stars; (2) the maximum and the minimum brightnesses of the observed m(pg), which were determined by visual estimation using the brightnesses in Catalogue USNO A2.0; (3) finding charts of the variables together with their comparison stars used (in electronic form only).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
