Physical properties

NGC 80 is classfied as a giant lenticular galaxy. Its circumnuclear ring measured 5″t 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. [6]

NGC 80 group

NGC 80 is the brightest cluster galaxy of the NGC 80 group, a galaxy group named after it. [7] Other galaxies that forms the group are NGC 79, NGC 81, NGC 83, NGC 85, NGC 86, Arp 65 (NGC 90 and NGC 93, NGC 94, NGC 96, IC 1542 and IC 1546. [8]

According to astronomers who studied the budges of seven members in the NGC 80 group in 2008 using the BTA-6 telescope, they discovered the stars have an estimated age of between 10 to 15 billion years old. However, IC 1548 (another member of the NGC 80 group) 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. [7]

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. [9]

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC (New General Catalogue) 598. With the D25 isophotal diameter of 18.74 kiloparsecs (61,100 light-years), the Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way.

An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are one of the four main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, along with spiral and lenticular galaxies. Elliptical (E) galaxies are, together with lenticular galaxies (S0) with their large-scale disks, and ES galaxies with their intermediate scale disks, a subset of the "early-type" galaxy population.

NGC 4036 is the New General Catalogue identifier for a lenticular galaxy in the northern circumpolar constellation of Ursa Major. In the Carnegie Atlas of Galaxies, it is described as being "characterized by an irregular pattern of dust lanes threaded through the disc in an 'embryonic' spiral pattern indicating a mixed S0/Sa form." It is located near the Big Dipper, a little to the north of the mid-way point between the stars Alpha Ursae Majoris and Delta Ursae Majoris. With a visual magnitude of 10.7, it can be dimly viewed using a 4 in (10 cm) aperture telescope.
