What are other binary stars like Albireo?

Question

also, are there any other binary stars with each star giving off a different color?

ok, I specifically need a binary star system with only two stars that are of different colors.

Answer 1

Struve 3053 in Cassiopeia - gold and blue
Eta Cassiopeiae - yellow and garnet
Almach (in Aindromeda) - topaz and aquamarine
Gamma Leporis in Lepus - yellow and garnet
h3945 in Canis Major - red and green-blue
Iota Cancri - orange and blue
70 Ophiuchi - yellow and red
24 Coma Berenices - orange and emerald
Izar in Bootes - yellow and blue-green
Xi Bootis - yellow and red
Kappa Herculis - yellow and garnet
Antares in Scorpio - red and emerald
Ras Algethi in Hercules - orange and blue-green
Omicron Ophiuchi - orange and blue
95 Herculis - apple green and cherry red
Omicron Cygni - orange and blue
Gamma Delphini - yellow and pale green
Delta Cephei - orange and glue.
There are a lot of others (I'm sure you could find more with just a little research).

Answer 2

VV Cephei is an eclipsing binary star system located in the constellation Cepheus. It contains a red supergiant which fills its Roche lobe when closest to its companion blue star, which appears to be on the main sequence; matter flows from the supergiant onto the blue companion. The stars are located about 3000 light years away from Earth.

VV Cephei A

VV Cephei A, the supergiant, is one of the largest stars known. It is of spectral type M2 and is about 1600–1900 times the Sun's diameter. If it replaced the Sun in our solar system, it would extend past the orbit of Jupiter and near that of Saturn. It is 275,000-575,000 times as luminous as the Sun. As is true for many red supergiants, it has a stellar wind flowing off of it with a velocity of about 25 kilometers per second.

VV Cephei B

VV Cephei B, the blue main sequence star, is separated from the larger star by a distance of 25 AU on average, with the distance varying between 17 and 34 AU. It is a B0 star about 10 times the Sun's diameter and about 100,000 times its luminosity. The orbital period of the system is 7430 days (20.3 years). The eclipse lasts about 1300 days, and is total for about a year and a half. The midpoint of the last eclipse was in early January 1998.

Answer 3

Mizar and Alcor in the handle of the Big Dipper.

Sirius A and B (white dwarf) in Canis Major.

Algol, actually a triple-star system, Beta Persei A, B and C in Perseus.

Cygnus X-1, variable star with a black hole in Cygnus.

Eta Sagittarii

Theta Orionis

Antares -- Red Giant orbited by a White Dwarf.

Answer 4

Sirius one of the brightest stars in the eastern sky is a binary star composed of a red giant orbited by a white dwarf.

Answer 5

My favorite is Epsilon Boötis, also known as Izar or Pulcherrima. It's a beautiful topaz and sapphire combination. This is a more challenging double to split than Albireo, but worth the effort.

Answer 6

A great percentage of stars are suspected of being in a multi-star system-- half, or perhaps better than half.
