What is the absolute magnitude of Alrisha (the celestial body in Pisces)??

Question

I know the apparent magnitude is +4.33+5.23...THANKS!!

Answer 1

Alrisha or Alpha Piscium (α Psc / α Piscium) is a star in the constellation Pisces. It also has the traditional name Alrischa or Alrescha (Arabic for "the rope").

The distance to α Psc is 139 light years. Thus it is 42.6 parsecs away. Its absolute magnitude (how bright it would look if it were a mere 10 parsecs away) is 0.67.

The system comprises a close double star with angular separation of presently 1.8" between the components. The main star is of apparent magnitude +4.33 and spectral type A0p, while the companion is of apparent magnitude 5.23 and belongs to spectral class A3m.

The two stars take more than 700 years to orbit one another and they will make their closest approach to each other around 2060. One or both of the stars may be a spectroscopic binary as well. The stars have masses of 2.3 and 1.8 solar masses respectively and shine with a total luminosity of 31 and 12 times that of the Sun.

While only third brightest in the ancient and sprawling zodiacal constellation of Pisces, the Fishes, Alrescha has a central place, at the southeastern point of two lines of stars that represent the ribbon that connects the two celestial fish, and thus was chosen by Bayer to be the Alpha star. At mid-fourth magnitude (3.94), it is not third by much, and is exceeded only by brighter fourth magnitude Eta and Gamma.

The binary stars average about 120 astronomical units (three times the distance between Pluto and the Sun) apart, the distance varying from 50 to 190 AU over the 720-year period. Each star has been reported as a spectroscopic double, rather like those that make Mizar.

Answer 2

Alpha Piscium

Answer 3

Hi. Actually a double star. So two absolute mags. http://www.answers.com/main/ntquery?s=Alrisha&gwp=13
1.74 and 1.4 are the Absolute mags of an A0 and A3 star, similar to the two stars in Alrisha http://www.rasnz.org.nz/Stars/BrightStars.htm

Answer 4

3.79

Answer 5

3.94
