The nucleus of NGC 536 is characterised as a
low-ionization nuclear emission-line region (LINER), a type of
active galactic nucleus.[4][5] The galaxy features a bright inner region, surrounded by a ring from which emanate two faint arms with
H II regions. These extended
spiral arms have been suggested to be
tidal tails. The galaxy has very weak
Hα 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]
One
supernova has been observed in NGC 536, SN 1963N. It was discovered by the
Palomar Supernova Search on June 27, 1963, with mag 17.7.[9]
