Flashcards
What is T Coroni Borealis?
What is T Coroni Borealis?
A binary star system consisting of a white dwarf and a red giant, where the white dwarf accretes material from the red giant, eventually leading to a thermonuclear explosion causing a nova.
What is a Nova?
What is a Nova?
A thermonuclear explosion on the surface of a white dwarf, caused by the accretion of material from a companion star, leading to a sudden increase in brightness.
What is Accretion in T Coroni Borealis?
What is Accretion in T Coroni Borealis?
The process where a white dwarf draws material from its companion star, slowly increasing its mass until it explodes as a nova.

Study Notes
T Coroni Borealis
- T Coroni Borealis is a binary star system 3,000 light-years away
- The system consists of a white dwarf and a red giant
- The white dwarf accretes material from the red giant
- This process causes the white dwarf to reach a critical threshold, leading to a thermonuclear explosion
- The explosion is what causes the Nova to be visible from Earth as a bright new star
- The phenomenon has been observed approximately every 80 years, with the last grand display observed in 1946.
Observing T Coroni Borealis
- The Nova is located in the constellation Corona Borealis
- The constellation resembles a crown and is visible near Vega and Arcturus
- The best time to observe the event is on a cloudless moonless night
- To minimize light pollution, observe from a dark location away from city lights
- Use star maps and astronomical apps for guidance
- Allow your eyes to adjust to the darkness for at least 30 minutes to maximize visibility.
Other Notable Celestial Events
- A total solar eclipse will occur, where the moon casts its shadow on the Earth, momentarily dimming the sun.
- The green comet 12P/Pons-Brooks is making a return, offering a glimpse of a primordial object.
