With my 4 f/9.8 refractor & Televue 10.5mm Plossl, provides a nice 95x . Gamma Leonis (γ Leonis, abbreviated Gamma Leo, γ Leo), also named Algieba / æ ˈ dʒ iː b ə /, is a binary star system in the constellation of Leo. THE PHOTOSPHERIC MAGNETIC-FIELD OF THE DM3.5E FLARE STAR AD LEONIS. Some sources give the stellar classification K1IIIFe-1 or K1IIIbCN-0.5, indicating an underabundance of iron (Fe) and cyanogen (CN). The asterism appears like a backward question mark with Regulus, the 21st brightest star in the sky .
Gamma Leonis-1 has about 180 times the Sun's luminosity. Definitions of gamma leonis, synonyms, antonyms, derivatives of gamma leonis, analogical dictionary of gamma leonis (English) .
Gamma 1 Leonis b is a gas giant exoplanet that orbits a K-type star. The asterism appears like a backward question mark with Regulus, the 21st brightest star in the sky . Gamma-2 Leonis, stellar object. The second-brightest star in the Sickle is Gamma ([gamma]) Leonis or Algieba, which a telescope reveals to be a fine double star (separation 4.5 arcseconds) with both components pale yellow-orange.
Discovered by William Herschel in 1782, Algieba is comprised of magnitude 2.4 and 3.6 stars currently separated by 4.6 arc-seconds.
Algieba visual magnitude is 2.61. Page 1 of 3 - Gamma Leonis - posted in Double Star Observing: There is a star in the sickle in the constellation of Leo that is without a doubt a showpiece! Being a binary/double star system its magnitudes are approx. Gamma Leonis-1 is the primary star of a binary star system with Gamma Leonis-2 being the secondary. It gives a quick overview of the hierarchical architecture. This is a result of Al Gieba's cooler surface temperature (4401 degrees Kelvin, next to 13,000 for Regulus). They form a slowly widening binary system with an orbital period estimated at between 5 and 6 centuries. April: the Lion Rampant: after dusk in early spring, Leo prowls at his highest DN Leonis is a main star in the constellation Perseus and makes up the constellation outline.
Based on the spectral type (G8III+.) Some sources give the stellar classification K1IIIFe-1 or K1IIIbCN-0.5, indicating an underabundance of iron (Fe) and cyanogen (CN). Its called Algieba or Gamma Leonis.
In 2009, a planetary companion around the primary was announced. Page 1 of 3 - Gamma Leonis - posted in Double Star Observing: There is a star in the sickle in the constellation of Leo that is without a doubt a showpiece!
Discovered by William Herschel in 1782, Algieba is comprised of magnitude 2.4 and 3.6 stars currently separated by 4.6 arc-seconds.
The primary component, Gamma 1 Leonis, is an orange giant star of the spectral type K1 III.
DN Leonis is a main star in the constellation Perseus and makes up the constellation outline. Based on the spectral type (A3Vvar) of the star, the star's colour is blue - white . ‹ Back to list.
Thanks to its high brightness, Algieba is clearly visible when observed from locations with dark skyes, and should be also quite easily visible from light polluted areas. Gamma Leonis-1 is the primary star of a binary star system with Gamma Leonis-2 being the secondary. The Astrophysical Journal: an international review of astronomy and astronomical physics. Gamma Leonis (γ Leonis, abbreviated Gamma Leo, γ Leo), also named Algieba / æ ˈ dʒ iː b ə /, is a binary star system in the constellation of Leo.
γ2 Leonis (gamma2 Leonis) γ2 Leonis is a variable and multiple giant star in the constellation of Leo . 2.4,3.6 with 4.4 seperation.
The golden components of Gamma Leonis, magnitudes 2.2 and 3.5, spectral types K0 and G7, are currently 4".4 apart -- close enough to make a tight, interesting binary, but not so close that they're hard to resolve in any telescope. Being a binary/double star system its magnitudes are approx. DN Leonis is a Giant Star type star.
Its discovery was announced in 2009.
DN Leonis Facts. γ2 Leonis visual magnitude is 3.8. Gamma Leonis-1 Always been seen Known by the ancients Gamma Leonis-1 b Mass = 1.23 Solar mass Radius = 31.88 Solar radius Effective temperature = 4330 K K-type star located at 126 light-years away from in the Leo constellation.
This is every star brighter than magnitude 6.5 within 50 light years, so all of these stars can be seen with the naked eye although most of them are quite faint. Adhafera is one of the six bright stars that form the Sickle of Leo, a conspicuous asterism that outlines the head and shoulders of the celestial Lion.Other stars that form the Sickle are Regulus (Alpha Leonis), Eta Leonis, Algieba (Gamma Leonis), Rasalas (Mu Leonis), and Epsilon Leonis. Its the next brightest star after Regulus.
Denebola is a main star in the constellation Leo and makes up the constellation outline. Facts. Its called Algieba or Gamma Leonis. The Variable Type is usually named after the first star of that type to be spotted.
The star is a pulsating Omicron Ceti variable type which means that its size changes over time. Gamma Leonis b, planet, semi-major axis: 1.19 ±0.02 AU. Al Gieba (Gamma Leonis) The gamma star of the lion is located just north of Regulus, and forms an interesting color contrast; the bluish color of the alpha star is very different from Al Gieba's yellow. Because of its moderate brightness, γ2 Leonis should be easily visible from locations with dark skyes, while it can be barely visible, or not visible at all, from skyes affected by light pollution.
