NGC 3883 is a large[3]low surface brightness[4][5]spiral galaxy located about 330 millionlight-years away[6] in the constellationLeo.[7] NGC 3883 has a prominentbulge but does not host anAGN. The galaxy also hasflocculent spiral arms in its disk.[5] It was discovered by astronomerWilliam Herschel on April 13, 1785[8] and is a member of theLeo Cluster.[3][9]
Despite being rich in neutral atomichydrogen (HI), NGC 3883 is very red and has a low amount ofH-alpha emission.[10][3] This suggests thestar formation in the galaxy ended a long time ago while the inner regions continued to form stars that enriched theinterstellar medium (ISM) and eventually used up the remaining gas. Possibly, the outer regions of NGC 3883 went through only a few generations of star formation because theHI density has been low throughout the galaxy's life.[3] However, J. Donas et al. suggests that theUV emission of NGC 3883 which comes mainly from the disk of the galaxy is coming from young intermediate mass stars and reveals star formation in the outer regions of NGC 3883.[10]
Because of a low amount of star formation[11][12] ongoing in NGC 3883, it has been classified as ananemic galaxy.[12]
