New H-alpha emission stars towards the galactic bulge
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=0o and b=0o distorted probably due to strong interstellar extinction.
Based on observations collected at the European Southern Observatory at La Silla (Chile).- Publication:
