luminous blue variable
(LBV, S Doradus variable)
(type of extremely bright variable stars)
A luminous blue variable (LBV or S Doradus variable after
an example in Large Magellanic Cloud) is a classification
of variable star that is extremely bright and extremely rare.
They are the most luminous stars known, with luminosities
hundreds of thousands times that of the Sun
and some of them experience outbursts (LBV outbursts) bright enough to be
mistaken for supernovae.
They are also among the most massive stars, up to 100 solar masses.
In addition to the Milky Way, examples have been identified
in other galaxies including the Magellanic Clouds, Andromeda, and Triangulum Galaxy,
and they have been used to estimate distances to the latter two
galaxies.
Explanation of their structure and evolution
continues to be a topic of research.
