The nucleus of NGC 536 is characterised as alow-ionization nuclear emission-line region (LINER), a type ofactive galactic nucleus.[4][5] The galaxy features a bright inner region, surrounded by a ring from which emanate two faint arms withH II regions. These extendedspiral arms have been suggested to betidal tails. The galaxy has very weakHα emission.[3] The star formation rate in NGC 536 is estimated to be 1.16[6] – 1.25[7]M☉ per year. The galaxy is seen with inclination of 78 degrees.[8]
Onesupernova has been observed in NGC 536.SN 1963N (type unknown, mag. 17.7) was discovered by Howard S. Gates on 27 June 1963, as part of the 1963Palomar Supernova Search.[9][10]
