Nuevas Nebulosas Planetarias y objetos con emisión en la región del Centro Galáctico; Nuevas Nebulosas Planetarias y objetos con emisión en la región del Centro Galáctico; New Planetary Nebulae and Emission Objects in the region of the Galactic Center
In an area of about 600 square degrees and centered in the region of the galactic center there have been found 437 objects with strong Hα in emission, from which 121 correspond to the given position of planetaries previously discovered, 67 are classified as new planetaries, Table I, and 48 as possible planetaries, Table II, or in a few cases, as bright nebulae. A glance at the apparent distribution of these planetaries convinces one that these are highly concentrated towards the galactic center with a marked tendency of symmetrical distribution with regard to the galactic plane. Analogy suggests that the three dimensional system of these planetaries may be coexistent and concentric with the nucleus of our galaxy. If this is true, then the planetary nebulae may provide us with an independent means to determine the center and the probable dimensions of the nucleus of our stellar system.
