2019年1月15日 · In this paper, the density and mass variation with the distance from the center of the galaxy NGC 3198 is studied depending on its observed rotation curve (Rubin et al. 1977). …

The galaxy NGC 3198 was discovered on 15 January 1788 by the German-British astronomer William Herschel with his self-built 18.7 inch f/12.8 reflecting telescope in Slough, England. [ …

We model the spiral galaxy NGC 3198 as consisting of three “luminous” components, namely the bulge and the stellar and the gaseous disks, which are embedded in a dark halo. To study the …

NGC 3198 is a Spiral Galaxy in the Ursa Major constellation. NGC 3198 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its …

This object is a weakly barred 10th magnitude spiral galaxy located 50 million light years away in the constellation of Ursa Major. The galaxy is large at a diameter of 140,000 light years. It is 10...
