NGC 5483 is abarred spiral galaxy in the constellationCentaurus. The galaxy lies about 60 millionlight years away from Earth, which means, given its apparent dimensions, that NGC 5483 is approximately 60,000 light years across.[1] It was discovered byJohn Herschel on March 15, 1836.[3]
NGC 5483 has a smallbulge and a small bar. From the ends of the bar emerge two well definedspiral arms in agrand design pattern. The arms have initially some knots but their outer parts are smoother. They fade after completing about half a revolution, when they became wide and diffuse.[4] The galaxy has a faint outer arm to the north.[5] There are also visible spiral arcs, which do not appear to be branched of the principal arms, and dust lanes. The galaxy has a large complexHII region that is about 4 arcseconds across.[6] Thestar formation rate of the galaxy is estimated to be about 3.1M☉ per year.[7] In the centre of the galaxy lies asupermassive black hole, whose mass is estimated to be 106.79 ± 0.38 (2.6 - 15 millions)M☉, based on the pitch angle of the spiral arms.[8]
One supernova has been detected in NGC 5483, PSNJ14102342-4318437. It was discovered on 15 December 2015 byMASTER at an apparent magnitude of 14.4.[9] It was classified spectrographically as atype Ib supernova.[10]
