NGC 1433 (also known as PGC 13586) is a barred spiral galaxy with a double ring structure located in the constellation of Horologium. It was discovered by James Dunlop on 28 September 1826, [5] and lies a distance of 46 million light-years from Earth. [4]
NGC 1433 is a Seyfert galaxy with an active galactic nucleus. The central region of the galaxy displays intense star formation activity, with an irregular star-forming ring of 5″ (or 0.3 kpc) radius and weak radio wave emission. Star formation is also noticeable in the spiral arms but not the bar of the galaxy. [6] NGC 1433 is being studied as part of a survey of 50 nearby galaxies known as the Legacy ExtraGalactic UV Survey (LEGUS). [7] A jet of material flowing away from the central black hole of the galaxy extending for only 150 light-years has been found. It is the smallest molecular outflow ever observed in a galaxy beyond our own. [8]
NGC 1433 is member of the Dorado Group. [4] [9]
One supernova has been observed in NGC 1433. SN 1985P (Type II, mag. 13.5) was discovered by Robert Evans on 10 October 1985. [10] [11] [12]
