NGC 536

NGC 536 is a barred spiral galaxy located in the constellation Andromeda. It is located at a distance of circa 200 million light years from Earth, which, given its apparent dimensions, means that NGC 536 is about 180,000 light years across.[1] It was discovered by William Herschel on September 13, 1784.[2] It is a member of Hickson Compact Group 10, which also includes the galaxies NGC 529, NGC 531, and NGC 542.[3] It belongs to the Perseus-Pisces Supercluster.

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 HII regions. These extended spiral arms has been suggested that they may 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]
