T Coronae Borealis (T CrB), nicknamed the Blaze Star, is a binary star and a recurrent nova about 3,000 light-years (920 pc) away in the constellation Corona Borealis. [10] It was first discovered in outburst in 1866 by John Birmingham, [11] though it had been observed earlier as a 10th magnitude star. [12]

5 天之前 · During the nova eruption, the star T Coronae Borealis will brighten from magnitude 10 to 2, which is visible to the naked eye. Here is what you need to know about this event. T CrB star explosion date: Has T Coronae Borealis gone nova yet? T …

18 小时之前 · The first recorded sighting of the T CrB nova happened more than 800 years ago, and the cycle repeats itself roughly once every 79 years on average. The last two previous explosions occurred in ...

2 天之前 · T CrB is expected to reach an apparent magnitude of +2 when it finally explodes. That’s about the same as Polaris, the North Star, the 48th brightest star in the night sky. It should be clearly ...

2 天之前 · T CrB is a symbiotic binary, a vampire system in which a white dwarf is siphoning material from a red giant star. A white dwarf is the dense, compact core remnant of a once sun-like star, ...

2024年9月29日 · T Coronae Borealis, or T Cor Bor for short, belongs to an elite club of ten recurrent novas known across the Milky Way, our home galaxy, offering astronomers a rare front-row seat to closely...

Currently, T CrB is 0.8 mag fainter than expected in the B-band, and 0.35 mag fainter than expected in the V-band. This plot proves that T CrB is now well into its long expected Pre-eruption Dip, having started sometime around the end of March 2023.

2025年1月28日 · As we reported last year, astronomers and hobby stargazers are on standby for the eruption of T Coronae Borealis, also known as T CrB or the Blaze Star. T Coronae Borealis is normally invisible to the naked eye. But every 80 years or so, it erupts in a thermonuclear explosion and—for a few days only—becomes one of the 50 brightest stars in ...

3 天之前 · T CrB is a binary system 3000 light-years from Earth, consisting of a white dwarf and a red giant. The latter slowly loses hydrogen to the moon’s gravity, forming an accretion disk around it. When enough material accumulates, a thermonuclear explosion occurs that scatters the matter into space. Unlike ordinary supernovae, the white dwarf ...

2024年11月4日 · Located 3,000 light-years away, T Coronae Borealis — T CrB for short — contains two stars that orbit each other: a red giant nearing the end of its life and an Earth-sized stellar remnant known as a white dwarf.
