Tau Orionis ye una xigante azul de tipu espectral B5III con una temperatura efectivo de 14.100 K.Incluyendo una gran cantidá radiación ultravioleta emitida, Tau Orionis relluma con una lluminosidá 3100 vegaes mayor que la del Sol.Con un radiu 9,4 vegaes más grande qu'el radiu solar, la so velocidá de rotación proyeutada —43 km/s— implica un periodu de rotación inferior a 11 díes. . . In fact, as it turns out, Herschel didn’t provide a position angle for the star he included in his 1780 description (twelfth title down): . RA: 05h 14.5m    Dec: – 08° 12’ A search for "60mm" will find all doubles where we used that size telescope. Until then, clear skies! Now Sirius is another matter I have attacked it a . But despite their battle with the glare, they were persistent enough to stay in view without resorting to averted vision. So in some ways this is a sojourn down one of the more difficult paths to double star nirvana, but it’s more a steady uphill climb than a hand-over-hand hoist to the top of a steep precipice. SIMBAD; Jim Kaler. . Cette étoile, avec β Eri, λ Eri et ψ Eri constituent Al Kursiyy al Jauzah, « la chaise (ou Footstool) de la (l'étoile) centrale »[1]. . Using 245x on a night like this would normally be a sign of sitting in one place under a cold dark sky for too many hours, but since the night was still young, I convinced myself that since I didn’t expect anything more than unfocused blobs of bouncing light, I was still on the safe side of insanity. But it’s close enough to give you a reasonable idea of what to expect. STF 668  A,BC:  0.30,   6.80               9.30”                  204°              2011 After all, Rigel is very splittable with a 60mm refractor, although I can’t say the same for Tau (τ). Sur une ligne imaginaire tracée entre les étoiles Rigel et Mintaka, Tau Orionis est située à environ à un sixième de la distance à Mintaka. He did get a slight break – apparently the separation of the BC pair was close to 0.20”, as opposed to 0.10”. . Burnham must have felt when he saw the elongation in Rigel’s BC pairing. .

Credit for the inspiration to visit Tau (τ) goes to both Chris Thuemen, who sent me a photo of it hinting at an elongation in the BC pair — which in turn launched me on a long search for a good photograph of Tau BC — and to Steve Smith who went out and took the photo I was looking for. Bintang ini dikenal dengan nama Yuh Tsing, yang berarti "sumur emas" atau "sumur jade".Nama lainnya untuk bintang ini adalah: If an imaginary line is drawn north-west between the stars Rigel and Mintaka, Tau Orionis can be found roughly one-sixth of the way to Mintaka. (East & west reversed to match the SCT view, click on the sketch to re-live the experience). As temptation for what’s possible, here’s a photograph of the Tau (τ) system taken by Steve Smith which provides a good view of a distinctly separated BC pair. . . They both also boast of doubled up secondaries, but with the difference that the average backyard double star diehard has a fighting chance to wrestle Tau’s BC pair apart. Not only was it done with a six inch refractor, but it was done twice. , _______________________________________________________, Update: Giving into the “temptation for what’s possible.”. . say is maybe I saw :something; but not very exciting at all.
