Spiral structure in NGC 1566. (1990). Revista Mexicana De Astronomía Y Astrofísica, 21(1), 126. https://astronomia.unam.mx/journals/rmxaa/article/view/1990rmxaa..21..126p
Abstract
A Fourier analysis of H II regions distribution of NGC 1566 in terms of logarithmic spirals is done. Firstly, the method is used to determine the position angle P.A. and the inclination ω of the galaxy. The decomposition into individual spiral components shows that a two-armed component is dominant in this galaxy. The authors calculate the surface density to reconstitute the galaxy using the most important components.Similar Articles
