The stellar distribution in Puppis - I. Distribution of B5 to M5 stars to V= or ^ 12.5.
Abstract
FitzGerald (1968) pointed out the existence of an unusually low-absorption Galactic plane field in the constellation Puppis. In view of its remarkably low extinction for a Galactic plane field, the 'Puppis window' is an ideal field for the conduction of a study of distant stellar tracers with a view to investigate the extent of the Galactic disk and to isolate distant blue-star candidates suitable for Galactic rotation curve studies. For this reason, the present investigation is concerned with a detailed study of the stellar distribution in that field. A classical space density analysis is conducted of the B5 to M5 stars to V approximately 12.5 in a 7.75 square degree area of sky centered on (1, b) approximately (245 deg, 0 deg). This work extends knowledge of the stellar distribution in the Puppis window to include all stellar types to a uniform limiting magnitude.
