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.
