In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
Together with the radial velocity, the total velocity can be calculated. Stars with high rates of proper motion are likely to be relatively close to the Sun, making them good candidates for parallax measurements. [145] When both rates of movement are known, the space velocity of the star relative to the Sun or the galaxy can be computed. Among ...
The final fate of the star depends on its mass, with stars of mass greater than about eight times the Sun becoming core collapse supernovae; [102] while smaller stars blow off their outer layers and leave behind the inert core in the form of a white dwarf. The ejection of the outer layers forms a planetary nebula. [103]
The oldest stars observed thus far, [10] known as population II, have very low metallicities; [16] [6] as subsequent generations of stars were born, they became more metal-enriched, as the gaseous clouds from which they formed received the metal-rich dust manufactured by previous generations of stars from population III.
A red supergiant star orbited by a smaller B-type main-sequence star with a radius estimated between 13 [54] and 25 R ☉. [55] Widely recognised as being among the largest known stars. [ 21 ] Another estimate give a radius of 660 R ☉ [ 25 ] based on the Gaia DR3 distance of 1 kpc.
No, actually -- even NASA is calling this star the "loneliest" in the universe. "The unusual object, called CX330, was first detected as a source of X-ray light in 2009," according to a NASA news ...
YZ Ceti is a variable star designation: the star shows occasional rapid and brief increases in brightness, sometimes reaching magnitude 12.03, caused by eruptions from the surface. This type of variable star is known as a UV Ceti star after its first member, or more colloquially as a flare star .
