It's believed that when the partner exploded as … They are both “G” class main sequence stars, the difference between the “2” and the “1” indicates that Zeta 2 Reticuli is a little hotter than the Sun. In Orion (as shown in the Figure above) the bright, red star in the upper left named Betelgeuse (pronounced BET-ul-juice) is not as hot than the blue star in the lower right named Rigel. At magnitude 4 it appears as a dim star visible to the unaided eye away from city lights. The star AE Aurigae is a young, newly-formed star with quite a lot in common with the star Zeta Ophiuchi. Measurements of the equivalent width and the intrinsic width of two lines CH 3879 and CH 2886 in the direction of Zeta Ophiuchi are presented. Sabik is a main star in the constellation Ophiuchus and makes up the constellation outline. Those winds create a "bow shock" in surrounding clouds of gas and dust. An upper limit on the R (2) line of 2.6 mA, yielding N (J=2) < or =1.66 x 10/sup 12/ cm/sup -2/ implies a rotational temperature of at most 22 K, with a high probability that T/sub rot/< or =16 K.

The star Zeta Ophiuchi, about 370 light-years from Earth, is rocketing through space at nearly 90,000 kilometers per hour. Publication Abstracts Bortolot 1972. Garafsa Colour and Temperature . The stellar classification of this star is O9.5 V, with the luminosity class of V indicating that it is generating energy in its core by the nuclear fusion of hydrogen. Zeta Ophiuchi is actually a very massive, hot, bright blue star plowing its way through a large cloud of interstellar dust and gas. Both Lambda Ophiuchi B and C are less massive than the primary, with estimated masses of 1.90 and 0.72 solar masses. The star has a B-V Colour Index of 0.03 which means the star's temperature is about 9,140 Kelvin. Lambda Ophiuchi B has the stellar classification A4V. Zeta Draconis; zeta function; Zeta Geminorum; Zeta Hydrae; Zeta Leonis; Zeta … The star, called Zeta Ophiuchi, is a stellar behemoth with about 20 times the mass of our sun and would be 65,000 times brighter if it weren't surrounded by a thick blanket of dust. ζ Ophiuchi is an enormous star with more than 19 times the Sun’s mass and eight times its radius. Fourth brightest is Zeta Oph is hotter, heavier, more luminous, and larger. It is in the constellation Ophiuchus. This would imply a rotational temperature of not more than 22 K, with a more probable value of less than 16 K. Since total column density (3.2 x 10 to the 12th per sq cm) is found to be lower by a factor of approximately 4 than that which had been previously reported, substantial photo-dissociation of C2 is assumed. Some believe that they are focused on enslaving the world’s population, though it is unclear why. With a surface temperature of 8,831 K, it shines with about 76 solar luminosities. The B8 star is cooler and less massive. Application of the techniques is illustrated by developing a successful model of the diffuse interstellar cloud toward Zeta Ophiuchi. Based on the star's spectral type of B2IV , Garafsa's colour and type is blue subgiant star. 2. Use, Smithsonian It puts … The projected rotational velocityma… Stellar System.

Parallax measurements give an estimated distance of roughly 366 light-years (112 parsecs) from the Earth. The results indicate that the molecular line widths have a substantial thermal component. A relation between the CH and CN molecular line widths in the Zeta Oph cloud is suggested. The star, called Zeta Ophiuchi, is a stellar behemoth with about 20 times the mass of our sun and would be 65,000 times brighter if it weren't surrounded by a thick blanket of dust. With an effective surface temperature of 6,873.50 K, it is about 164 times more luminous than the Sun. Like most luminous stars, Zeta Oph is losing mass through a strong wind that in this case blows at … A column density of 1.22 x 10 to the 12th per sq cm is derived from an absorption feature at the 4 sigma level of significance at the position of the R(0) line. It is 458 light years distant and were it not partly obscured by interstellar dust and gas would shine at almost first magnitude. In the false-color view, bluish Zeta Oph, a star about 20 times more massive than the Sun, lies near the center of the frame, moving toward the left at 24 kilometers per second. Parallax measurements give an estimated distance of roughly 366 light-years (112 parsecs) from the Earth. Sabik is a Main Sequence Star type star. The CN excitation temperatures, corrected for local processes, yielf T B (λ2.64 mm) = 2.75±0.10°K in ζ Oph and 2.66±0.12°K in ζ Per. This speed, combined with Zeta Ophiuchi’s huge output of stellar wind, causes a reaction with the surrounding matter: a vast, glowing, bow-shaped region called a bow shock. Like a ship plowing through cosmic seas, runaway star Zeta Ophiuchi produces the arcing interstellar bow wave or bow shock seen in this stunning infrared portrait. So basically the Sun is a little cooler and younger than Zeta 2 Reticuli. It is a binary star formed by Alpha Ophiuchi A, and Alpha Ophiuchi B. The interaction causes the clouds to glow brightly in infrared light. The temperature implied by the widths, about 1200 K, is much higher than those found from other diagnostic or found in any models of such clouds. Both Lambda Ophiuchi B and C are less massive than the primary, with estimated masses of 1.90 and 0.72 solar masses. Procyon A Altair Sun Alpha Centaun A .
