Gamma Geminorum (Alhena) is the third brightest star is Gemini, just a 0.3 magnitudes fainter than Alpha. Apparent Magnitude. Astronomical Name. Low-resolution SWP spectra and high-resolution LWR spectra of the SRc variable star TV Gem have been studied. Absolute magnitude (M)-0,68 B-V ... Alhena (ook bekend as Gamma Geminorum of γ Gem) is die derde helderste ster van die sterrebeeld Tweeling. Alhena (Gamma Geminorum) is a subgiant A star and the third brightest member of the constellation Gemini.Its Arabic name (alternatively given as Almeisan) refers to a brand on a horse or a camel. New spectroscopic observations of Gamma Geminorum, a bright, 'normal' A1 IV star have resulted in an improved spectroscopic orbit. Alhena marks the foot of the twin whose head is marked by Pollux, and marks the southwestern border of the constellation, near Orion's club. Alhena is the traditional name of star Gamma Geminorum and it is the second brightest star in the constellation Gemini, about 109 light years from the Earth , having Apparent visual magnitude of 1.9 . absolute magni-tude (M V) A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. The available ultraviolet spectrophotometry and UBV photometry of the system can be interpreted in terms of the blended light from a B3.5 IV star and an M1 Iab star. Xi Geminorum (ξ Geminorum, abbreviated Xi Gem, ξ Gem), formally named Alzirr / ˈ æ l z ər /, is a star in the zodiac constellation of Gemini.It forms one of the four feet of the outline demarcating the Gemini twins. The stellar distances are only fairly accurate for stars well within 1000 light years. Meaning. Mebsuta Apparent and Absolute Magnitudes.

We determine a v sin i of 8 +/-1 km/s for the A star, which confirms that it is a slow rotator. The following list contains the 100 brightest stars as seen from the earth at night. Apparent Magnitude is also known as Visual Magnitude. This is every star brighter than magnitude 3.55. Absolute Magnitude. Volgens parallaksmetings is dit sowat 109 ligjare van die Son af. The orbital period is 12.632 +/- 0.002 yr, the eccentricity is 0.893 +/-0.002, and the orbital parallax is 0.0291 +/-0.0024 arcsec, or a distance of 34 pc.

The Brightest Stars. It orbits the main white subgiant Alhena A following a highly eccentric path taking nearly thirteen years to complete. Common Name. Alhena (ook bekend as Gamma Geminorum of γ Gem) is die derde helderste ster van die sterrebeeld Tweeling.Met sy skynbare magnitude van 1,9 is dit een van die helderste sterre in die naglug en duidelik met die blote oog sigbaar. Distance measurements are from the Observer's Handbook 2001, by The Royal Astronomical Society of Canada. The star has an apparent visual magnitude of 3.35, which is bright enough for it to be seen with the naked eye. Alhena - γ Geminorum (gamma Geminorum) Alhena, also designated as γ Geminorum (gamma Geminorum), is a multiple hypergiant star in the constellation of Gemini. Met sy skynbare magnitude van 1,9 is dit een van die helderste sterre in die naglug en duidelik met die blote oog sigbaar. Alhena Apparent and Absolute Magnitudes.
