| contents | A dynamical model for the spiral galaxy ngc 3359 M. Rozas Física, Astronomía y Matemáticas galaxies: individual (NGC 3359) galaxies: kinematics and dynamics galaxies: spiral In this work we have determined a dynamical model for NGC 3359. This isa strongly barred spiral galaxy with a complex structure, within which we can seean annular zone of intense star formation. In this work we present self consistentnumerical simulations of molecular gas in NGC 3359; and using the potential derivedfrom an I band image, we attempt to find the parameters responsible for thekinematics and morphology of the observed gas. The best results are obtained fora two pattern speed model: the central region (up to 15´´) corresponding to thenuclear bar which rotates with a Ωs=100 km s−1 kpc−1; and the main bar + outerspiral, decoupled from the nuclear region, which rotates with a angular velocity, Ωp= 27 km s−1 kpc−1. The model successfully reproduces the complex structure inHα of the galaxy in the internal 20´´ zone, which cannot really be explained with aunique mode pattern. 2008 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57144105 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.44 |
