Ultraviolet image of the pseudo-ring structure in the center of the galaxy
Themorphological (shape) class of NGC 5962 in theinfrared is SAB(rs,nrl)c. This notation indicates the galaxy has abar structure around the nucleus (SAB), an inner pseudo-ring likely associated with the outerLindblad resonance (rs), a ring-lens structure at the nucleus (nrl), and loosely-woundspiral arms (c).[5] In theoptical band, this galaxy is classed asHubble type SA(r)c,[10] displaying an inner ring with no visible bar. Thegalactic plane is inclined at an angle of45°±2° to the line of sight from the Earth, giving it an oval profile with the major axis aligned along aposition angle of109°±4°.[11]
Along with a populated nucleus, it has a relatively largecore, but a smallcentral bulge, in which the spiral arms begin to unfurl. There is some evidence for a low level ofnuclear activity, and it has been classed as a nuclearH II region galaxy.[10] Based on its emission offar ultraviolet radiation, the pseudo-ring structure is actively undergoingstar formation.[12] The galaxy is forming stars at the rate of6 M☉·yr−1.[13] There are two confirmedsatellite galaxies; a third candidate proved to be too distant based on its redshift value.[14]
Twosupernovae have been detected in this galaxy:SN 2016afa (type II, mag. 17.1)[15] was discovered February 12, 2016, andSN 2017ivu (type IIP, mag. 15.4)[16] was spotted December 11, 2017.[17]
