Alpha-2 Canum Venaticorum variables are main sequence stars of spectral class B8p to A7p that are chemically peculiar and have strong magnetic fields and strong strontium, silicon or chromium spectral lines.
They are named after a star in the Cor Caroli system in the constellation Canes Venatici. Beta Coronae Borealis is light years distant from the solar system. It is the second brightest star in Corona Borealis. Gamma Coronae Borealis is a close binary star with an orbit of 91 years. The two components in the system are only 0.
Gamma Coronae Borealis is classified as a Delta Scuti variable or a so-called dwarf Cepheid , a star showing variations in luminosity as a result of both radial and non-radial pulsations of its surface.
It belongs to the spectral class A0. Zeta Coronae Borealis is another double star in the constellation. It consists of a pair of blue and white stars 7.
The system is approximately light years from the solar system. T Coronae Borealis is a recurrent nova, sometimes also known as the Blaze Star. It is a spectroscopic binary with a period of The star usually has a magnitude of about T Coronae Borealis is a red giant. It belongs to the spectral type M3III and is approximately 2, light years distant.
Rho Coronae Borealis is a yellow dwarf star with an apparent magnitude of 5. It belongs to the spectral class GVa and is considered a solar twin, with almost the same mass, luminosity and radius as the Sun. R Coronae Borealis is a yellow supergiant star, belonging to the spectral class F7, with an apparent magnitude of 6. It is about 6, light years distant. It is a variable star, with its brightness fading by several magnitudes at irregular intervals.
In the case of R CrB, the apparent magnitude ranges from 5. As the cloud of dust moves away from the star, it becomes brighter again. Nusakan, also known as Beta Coronae Borealis, is the second brightest star in Coronae Borealis and is located around light years away from us. A binary star, it has an apparent magnitude of that varies from 3. Gamma Coronae Borealis is located around light years away from us. It is a binary star with an apparent magnitude of 3. Its surface temperature is 7, K, making it hotter than our Sun and it is overall 59 times brighter than our Sun.
Theta Coronae Borealis is another binary star. It is located around light years away from us. Theta Coronae Borealis A is a blue-white star with a magnitude of 4.
Therefore, Theta Coronae Borealis has a combined apparent magnitude of 4. It has a temperature of 14, K, making it twice as hot and times brighter than our Sun. Delta Coronae Borealis is located around light years away from Earth. Delta Coronae Borealis is also Epsilon Coronae Borealis is around light years away from Earth. It is a multiple star system that has a combined apparent magnitude of 4.
Epsilon Coronae Borealis lies one degree north of the variable star T Coronae Borealis, which we will go into more detail about further on. It is times brighter than our Sun and has an exoplanet around 6. Iota Coronae Borealis is around light years away from us. It is a binary star with an apparent magnitude of 4. The chemically peculiar star is the primary star and it has a temperature of 10, K, making it twice as hot as the Sun and 90 times brighter. T Coronae Borealis is also known as the Blaze star and it is an unusual type of star known as a recurrent nova.
It usually has a magnitude of T Coronae Borealis is located at around parsecs away from us. It is a binary star with a red giant star and a white dwarf. It is times brighter than our Sun. Rho Coronae Borealis is a yellow dwarf star and is actually very similar to our Sun. It is located at around It is 1. It is also older than our Sun — around R Coronae Borealis is a yellow supergiant star that is located at around 1, parsecs and has an apparent magnitude that varies from 5.
It is the prototype of the R Cor Bor class of variable stars, which fade by several magnitudes at irregular intervals. The remainder is mostly carbon. It is also around 10, times brighter than our Sun. It is situated around It is cooler than our Sun, with a temperature of around 4, K, but it is It is the first first subgiant discovered to host a disk of dust around it. The disk extends to around AU. As well as the notable stars mentioned above, the Corona Borealis constellation also hosts some deep sky objects.
There are no Messier objects in Corona Borealis and no meteor showers are associated with this constellation. NGC is a member of the Abell galaxy cluster. It is a spiral galaxy that is located at around million light years away from us.
