    Study Notes

    Nova Outburst Prediction

    • A nova is a sudden, dramatic increase in brightness of a star, appearing as a new bright star.
    • Novas typically occur in binary star systems, composed of a red giant and a white dwarf.
    • Material from the red giant accumulates on the white dwarf, eventually causing an explosion.

    T Coronae Borealis (T CrB) Nova

    • T CrB is a binary star system approximately 3,000 light-years from Earth.
    • It is known for periodic nova outbursts.
    • The last outburst occurred in 1946.
    • The system's red giant and white dwarf orbit each other tightly.
    • The red giant loses mass, which then accumulates on the white dwarf.
    • This causes high pressure & temperature on the white dwarf, leading to an explosion.
    • The white dwarf survives each nova.
    • The event will be visible to the naked eye for several days.

    Prediction and Observation

    • NASA predicts a nova outburst from T CrB sometime before September 2024.
    • The exact timing is difficult to predict.
    • The nova will be visible without any equipment for several days.
    • Binoculars will enhance visibility for over a week.
    • The outburst will appear as a bright star in the northern sky.
