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 located 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 known optical components as well as the newly resolved white dwarf companions.

; 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.
the core of this volume are the 30 double page star atlas plates, beautifully designed by wil tirion at the handsome scale of 4 degrees per inch. the atlas shows all stars down to. The Cambridge Double Star Atlas Some recommended references Of the vast literature existing on the subject of double and multiple stars, here are a few of the most useful and interesting print and.

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.

“Cores to Clusters” workshop aimed at discussing the quests of star formation to be investigated with several of new generation telescopes such as Spitzer, ALMA, VLTI, SMA, CARMA and HERSCHEL. This book includes review type articles on star formation written by leading researchers and other more technical papers on related current issues.
