National Aeronautics and Space Administration.]. 56 Persei is at least a triple star and possibly a quadruple star system in the northern constellation of is visible to the naked eye as a dim point of light with a combined apparent visual magnitude of The system is located light-years ( pc) distant from the Sun based on parallax, but is drifting closer with a radial velocity of −32 km/llation: Perseus.
HR is a binary star system in the southern constellation of has the Bayer designation G Carinae, with HR being the star's designation in the Bright Star system is visible to the naked eye with an apparent visual magnitude of It is The white-dwarf companions of 56 Persei and HR 3643 book at a distance of approximately light years from the Sun based on parallax, and is drifting further away with a Constellation: Carina.
The 56 Persei and 14 Aurigae systems are found to be quadruple and quintuple, respectively, including the The white-dwarf companions of 56 Persei and HR 3643 book optical components as well as the newly resolved white dwarf companions.
Available in the National Library of Australia collection. Author: Landsman, Wayne R; Format: Book, Online; ix, 22 p. ; 30 cm. We have obtained low-dispersion IUE spectra of the stars 56 Persei (F4 V) and HR (F7 II), as part of a survey of late-type stars with a A flux excess in the TD-1 ultraviolet sky survey.
this is among the two or three most stimulating and encouraging books that one could give to an aspiring young astronomer or adult novice -- and i do not mean that as any form of condescension, but as high praise.

A star with less than about times the Sun’s mass spends the last stage of its life as a ä white dwarf. For a long time, white dwarfs keep shining because they are very hot to begin with but, since they cannot generate any new energy, they will gradually cool and fade into a dark stellar ‘‘corpse’’ or black dwarf.
