Constellation Regulus is the luminary of the constellation Leo. The Algieba star system (otherwise known as Gamma Leonis) is composed of a binary pair of giant stars: Algieba A (an orange K0 III giant), and Algieba B (an odd greenish-yellow G7 III giant). I checked the sky at midnight and saw that it was still cloudy, but knowing the forecast called for clearing, I turned in and decided to check back later.

And now for something totally different — a Refractor Review! Learn how your comment data is processed. For example, a search on "15h" will find all doubles we've reported on that have an RA of 15 hours. But then some double stars just always have that affect on me. Castor – three steps to take you from aw to awe! A bit better, but still not quite what I had in mind. Gamma Leonis (γ Leonis, abbreviated Gamma Leo, γ Leo), also named Algieba /æˈdʒiːbə/, is a binary star system in the constellation of Leo. Its apparent visual magnitude is 2.14, making it readily visible to the naked eye. But Saturn was calling me, and I saw a few clouds moving that way, so it was time to make a quick move before it was too late.

The WGSN's first bulletin of July 2016[16] included a table of the first two batches of names approved by the WGSN, which included Denebola for this star. Well – it’s real enough to me and selected other observers, but as the “The Night Sky Observer’s Guide”  by Kepple and Sanner explains, the two stars are really deep yellow and pale yellow. The Sun, in comparison, has an equatorial rotation velocity of 2 km/s.
A G star should be yellow. However, the high rate of rotation results in an oblate shape with an equatorial bulge.

In Hindu astronomy, Denebola corresponds to the Nakshatra (a sector along the ecliptic) named Uttara Phalgunī (second reddish one). The moon was up, Saturn was easy to pick out, Arcturus and Izar were calling to me, but over in the southwest I could see Leo – and above Regulus, I saw my target – Algieba! Kinematic studies have shown that Denebola is part of a stellar association dubbed the IC 2391 supercluster. Denebola has a high projected rotational velocity of 128 km/s, which is of the same order of magnitude as for the very rapidly rotating star Achernar.

Der Hauptstern ist ca. “Some observers have reported the companion to be greenish – but that is at least in part an optical illusion caused by the contrast of the deeper yellow of the primary with the paler yellow of the secondary.”. A 76mm f/15.7 Tasco, a 10.5mm Ortho (114x), a pale blue sky for a background, two sharply defined stars with traces of gold and yellow, surrounded by crisp diffraction rings ………….. if there had been a way to slow the earth’s rotation and hold back the daylight, I would have done it right then and there. So I grabbed a 60/800 refractor that was sitting on my Unitron alt-az mount and headed out into the drive instead. Aldebaran Radius has been calculated as being 44.13 times bigger than the Sun. Algieba is easy to find. Other stars in this association include Alpha Pictoris, Beta Canis Minoris and the open cluster IC 2391. It also bears the Flamsteed designation of 94 Leonis (assigned on the basis of increasing right ascension rather than luminosity) and additional designations followed as the star was recorded in subsequent star catalogues. .

I stayed with it a bit longer and managed to coax a couple of diffraction rings from each star, but finally decided to use the 10mm (80x) instead. Filed under: Leo | Tagged: Algieba, double star, gamma Leonis |. I know I have the right star when I look in the finder or low power eyepiece because 40 Leonis, a 5th magnitude star, is less than half a degree south of Algieba at about PA 189°. The binary star, Algieba. [22], This article is about the star.

On Algieba I got a split with the 10mm Tak Le, but it was much better with the 7.5 and it wasn’t until I put in the 5mm (120X) that the colors really came out.

The “apparent color” of a K star is “yellow orange” so that roughly fits my description for the primary. Change ), You are commenting using your Facebook account. In 2009, a planetary companion around the primary was announced. Separation          4.4″ Sorry, your blog cannot share posts by email.

Algieba ist der Name des Sterns γ Leonis (Gamma Leonis) im Sternbild Löwe.Der Name stammt aus dem Arabischen und bedeutet so viel wie Mähne des Löwen.. Algieba ist ein möglicherweise ein vierfaches Sternsystem, bei dem die beiden Hauptkomponenten in kleinen Teleskopen (ab 5 Zentimeter Objektivdurchmesser) trennbar sind. It was a Christmas scene out of Currier and Ives. This page was last edited on 22 March 2019, at 08:11. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[15] to catalog and standardize proper names for stars. Algieba neue Daten : Algieba ist der dritthellste Stern im Sternbild Löwen und hat damit die Bezeichnung gamma Leonis. That's the Miami Dolphins football team - they could use a new star this year - but that's not my department. Die scheinbare Helligkeit des Gesamtsystems beträgt 2,0 mag, der Hauptstern allein besitzt eine scheinbare Helligkeit von +2,3 mag und gehört der Spektralklasse K0 IIIb an. 6 Leonis – an orange with a violet puff ball as viewed from an icebox, The Anatomy of a Multiple Star: Krueger 60 (KR 60), Beyond the Weird and Wonderful World of 8 Andromedae: Σ 2987, OΣΣ 244, and OΣ 493, The Weird and Wonderful World of 8 Andromedae: BU 717, ES 2725, and ARY 3, STT Pairs in Cepheus: OΣ 32, OΣ 436, OΣ 458, and OΣ 461, STT Objects in Lacerta, Part 2: OΣ 459, OΣ 465, and OΣ 472, STT Objects in Lacerta, Part 1: OΣ 475, OΣ 477, and OΣ 479, Difficult Double Stars of the STT Variety, Problems of a Different Magnitude in Lacerta: 8 Lacertae (STF 2922/A1459) and ROE 47, Sleuthing in Sight of Sadalmelik: OΣ 460, Σ 2862, and Σ 2855, Left is Right and Right is Left – a simple users guide to PA.

In this case, for the graph G define: = {: → : ∑ ∈ ‖ ‖ < ∞}. Had my first view of Algieba for the fall of 2011 at 6:30 AM this morning, just as the sky was beginning to get pale blue — looks like about a month earlier than last year, judging by the date on the comment above. This link takes you to a companion site whose goal is to help you learn the night sky one bright star at a time. Von den beiden anderen Komponenten gibt es kaum Daten, so dass das System oft als Doppelstern betrachtet wird. It had been hopelessly cloudy  here for the total lunar eclipse on December 21, 2010 so, of course, the next night it was  brilliantly clear and I marveled at the brightness of the snow-covered landscape reflecting the just-past-full Moon’s light as I approached my small observatory. So the green business is persistent, but not entirely consistent!

My difficulty in picking up the color this time may have been due in part to the glare from the Moon because usually these colors jump out at me. I really would like to get a pristine split of that pair! Algieba – Gamma (γ)  Leonis [18] Al-Biruni, a Muslim scholar and polymath of the 11th century, wrote of it: "The heat turns away when it rises, and the cold turns away when it disappears."[18]. I also had no trouble getting a clean split with a 60mm refractor. This is really a great example of how the color of closely spaced stars is affected by contrasts. [6] Der Stern γ2 hat demnach (noch) keinen Eigennamen. In the Alphonsine Tables it was recorded as Denebalezeth. This is also one of my all time favorite doubles. Die Messungen der Umlaufdauer liegen bei etwa …
