Study Notes

Nova Explosions

Nova explosions are rare celestial events.
Nova explosions occur in binary star systems—a red giant and a white dwarf.
The red giant sheds material that accumulates on the white dwarf.
The accumulation of material causes an explosion known as a nova, resulting in a sudden increase in the system's brightness.
Nova explosions are typically observed with powerful telescopes.
The upcoming T Coronae Borealis nova eruption will be visible without aid.
