NGC 80

NGC 80 is a lenticular galaxy located in the constellation Andromeda. It is currently interacting with two other barred spiral galaxies NGC 47 and NGC 68, and was discovered on August 17, 1828, by John Herschel.

Physical properties

NGC 80 is classified as a giant lenticular galaxy. Its circumnuclear ring measured 5t 7 in radius, is 7 billion years with an older stellar population of 10 billion years. The galaxy also has a metal-rich chemically distinct nucleus.

NGC 80 is the brightest cluster galaxy of the NGC 80 group, a galaxy group named after it. Other galaxies that forms the group are NGC 79, NGC 81, NGC 83, NGC 85, NGC 86, Arp 65 was exceptional since it showed signs of recent star formations, with a budge and nucleus age calculated to be 3 and 1.5 billion years respectively. Moreover, IC 1548 also has a thin-like gas structure indicating its interaction caused it to become a lenticular galaxy.
The following year, the same telescope was used, this time to observe 13 disk galaxies in the group. Of the 13 galaxies, 9 were lenticulars. Astronomers also found there is one case of ongoing star formation in UCM 0018+2216 and that all galaxies studied exhibited a two-layered stellar disk brighter than M B ~ -18.
