Paddock. Orbit of [beta] Coronæ Borealis [electronic resource] / By J. (John Beattie) Cannon and Dominion Observatory (Canada) Abstract. Beta Coronae Borealis (also known as Nusakan) is a star system located in the galaxy's Alpha Quadrant, a trinary star consisting of three type F white stars.

It was visible from Sol in the constellation of Corona Borealis, in the vicinity of Zaran and Delta Herculis, near the borders of the First Federation.

(ST reference: Star Charts) Emil Vaslovik maintained a business front on Nusakan in. From a combination of speckle interferometric and visual measurements with recent radial velocities, an improved current orbit was derived for beta Coronae Borealis with a period of yr, an eccentricity ofperiastron atand a semimajor axis of arcsec and have combined this with a long Allegheny parallax series to.

The second brightest star, Beta Coronae Borealis (Nusakan), is a spectroscopic binary that is located light years away.

It is an Alpha-2 Canum Venaticorum (ACV) type star, a. Nusakan – β Coronae Borealis (Beta Coronae Borealis) Beta Coronae Borealis is a spectroscopic binary, with a period of years. It is an Alpha-2 Canum Venaticorum (ACV) type variable star with a period of days and a magnitude varying between and Beta Coronae Borealis (Beta CrB / β Coronae Borealis / β CrB), adalah bintang tercerah kedua pada rasi Corona un terlihat seperti satu bintang, tetapi sesungguhnya ia adalah bintang ganda Bintang ini berada pada jarak tahun cahaya dari Bumi dan bermagnitudo bervariasi antara dan β Coronae Borealis diumumkan sebagai bintang ganda pada tahunRasi bintang: Corona Borealis.

Located ±3 light-years away, Beta Coronae Borealis or Nusakan is a spectroscopic binary system whose two components are separated by 10 AU and orbit each other every years. The brighter component is a rapidly oscillating Ap star, pulsating with a period of ing constellations: Hercules, Boötes.

Alpha Coronae Borealis is a binary system, its stars orbiting each other in an eccentric orbit every days. Because the plane of this orbit is inclined at an angle of ° to the line of sight to the Earth, the pair form a detached eclipsing binary system similar to Algol (β Per).

The periodic eclipses result in a magnitude variation of + to +, which is hardly noticeable to the Constellation: Corona Borealis.

Situated in the galaxy's Alpha Quadrant, this system is in or near the space of the Federation in the general. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees.

For AA Coronae Borealis, the location is 15h 58m and +28° 16` Proper Motion of AA Coronae Borealis. All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun.

Beta Coronae Borealis (Beta CrB, β Coronae Borealis, β CrB), which has the traditional name Nusakan, [9] is the second brightest star in the constellation of Corona Borealis. Although it appears to the naked eye to be a single star, it is actually a binary star system.

[10] It is approximately light-years away and has an apparent visual magnitude which varies between and It got its name, Alphekka Meridiana (Alphekka South) after Alphecca, the brightest star in the northern constellation Corona Borealis.

β Coronae Australis (Beta Coronae Australis) Beta Coronae Australis is a K-type bright giant (spectral type K0II) with an apparent magnitude of. It is the second brightest star in Corona Borealis and is about light years away from the solar system.

Its traditional name, Nusakan, is originated from the Arabic word nasaqan which means ‘the (two) series’. Y Coronae Borealis (Gamma Coronae Borealis): It is basically a binary star with an orbit period of 91 years.

It is usually. Due to the dramatic changes of brightness, R Coronae Borealis is also known as the Fade-Out Star or Reverse Nova. Kappa Coronae Borealis is an orange subgiant belonging to the spectral class K1 approximately light years from Earth.

It has an apparent visual magnitude of A giant planet was discovered in the star’s orbit in The planet candidate orbiting Rho Coronae Borealis was one of the first exoplanet discoveries, with a radial velocity minimum mass of Jupiter masses.

Subsequent analysis of the Hipparcos astrometric data indicates that the companion is actually a low-mass star in a nearly face-on orbit, however this would make the system unstable.

edit. Theta Coronae Borealis estimated radius has been calculated as being times bigger than the Sun. The Sun's radius is ,km, therefore the star's radius is an estimated 2,km.

If you need the diameter of the star, you just need to multiple the radius by 2.

R Coronae Borealis star, any of a small group of old stars of the class called peculiar variables that maintain nearly uniform brightness for indeterminate lengths of time and then fall abruptly and dramatically in brightness over the course of a few weeks or less, returning slowly and irregularly to their previous level over several months.

Such stars are rich in carbon, and it is believed. Hydrogen deficiency and a sudden optical light decline of about mag are two principal characteristics of R Coronae Borealis (RCB) stars.

The high latitude carbon star HE was identified as a hydrogen-deficient carbon star from low-resolution spectroscopy. Alpha Coronae Borealis has two popular names: Alphecca, a shortened form of al-Munir al Fakka, the Arabic for “brilliant one of the bowl,” and Gemma, Latin for “jewel.” Double stars in Corona Borealis include Sigma Coronae Borealis, a pair of yellow stars that orbit each other every 1, years, and the blue-white pair Zeta Coronae.

Alpha Centauri A and B orbit around a common center with an orbital period of almost 80 years. They have an elliptical orbit which is a bit eccentric.
