Astrognome Scrapbook The Blaze Star, T Corona Borealis

T Corona Borealis

The famous ‘Blaze Star’ T Corona Borealis is the prototype of the recurrent Nova class of variable stars. Recurrent novae are stars that are seen to increase massively more than once. 



T CrB t reached a maximum brightness of magnitude 2.0 on May 12th 1866. This was the first time it had been observed. It brightened up again in 1946.


Although only a few recurrent novae are known but because of the length of time between outbursts there may be many more recurrent novae waiting to be discovered.
