NGC 7319
Template:Short description Template:Infobox Galaxy
NGC 7319 is a highly distorted barred spiral galaxy that is a member of the compact Stephan's Quintet[1] group located in the constellation Pegasus, some Script error: No such module "convert". distant from the Milky Way.[2] It was discovered on 27 September 1873 by French astronomer Édouard Stephan.[3]
The galaxy's arms, dust and gas have been highly disturbed as a result of the interaction with the other members of the Quintet. Nearly all of the neutral hydrogen has been stripped from this galaxy, most likely as a result of a collision with NGC 7320c some 100 million years ago.[4] A pair of long, parallel tidal tails extend southward from NGC 7319 in the direction of NGC 7320c, and is undergoing star formation.[5]
This is a type 2 Seyfert galaxy[2] with one of the largest circumnuclear outflows known in galaxies of this type. This outflow reaches velocities of up to Script error: No such module "val". and spans Script error: No such module "convert".. The star formation rate appears normal for a spiral galaxy at Script error: No such module "val". yr−1, and the majority (68%) is occurring in the spiral arms.[5] The core appears faint in the ultraviolet band, indicating heavy extinction within the active galactic nucleus.[5] There is a three component radio source with an overall size of Script error: No such module "convert". that is straddling the nucleus.[6] A strong X-ray source with a high redshift has been detected at a separation of Script error: No such module "val". from the galactic nucleus, a quasi-stellar object.[7]
One supernova has been observed in NGC 7319: On 19 August 1971, Leonida Rosino discovered SN 1971P (type unknown, mag. 16.8).[8]
