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.
