(recurrent nova expected to erupt sometime within 2024-2026)
T Coronae Borealis (T CrB) is a recurrent nova within the Milky Way
which has erupted periodically, roughly every 80 years over the last few
centuries, the most recent occurrence in 1946, and previous to that in 1866.
According to pattern, it would erupt in about 2026, and its
light curve shows features similar to those leading up to its 1946
eruption, thus there is anticipation regarding the opportunity
to study such a nova with current equipment and techniques.
(As of early 2026, it is predicted to erupt in June.)
It is a binary star consisting of a white dwarf and a
red giant.
Other such Milky-Way recurrent novae include
RS Ophiuchi (RS Oph) which has seven recorded eruptions, 1889 to 2021,
T Pyxidis (T Pyx) which erupted in 1944, 1967, and 2011,
and
IM Normae (IM Nor) which erupted in 1920 and 2002.
