This isn’t even the most interesting thing about it; the star is driving through the surrounding interstellar gas* at about 24 kilometers per second. 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. All objects in the universe emit thermal radiation. The bow shock is located about half a light-year in front of the moving star, marking the area where the particle wind collides and interacts with the surrounding space-gas. With a surface temperature of 8,831 K, it shines with about 76 solar luminosities. Musca - the heavenly fly. Main sequence stars are powered by the fusion of hydrogen (H) into helium (He) in their cores, a process that requires temperatures of more than 10 million Kelvin. Absolute Magnitude 61 Cygni A- 10-2 10-4 Kruger 60 A Sirius B Barnard Procyon B Proxima * UV Ceu LHS 2924 GD 1658 05 BO AO FO GO KO MO M10 Spectral type +15 Answer the questions using the above HR Diagram 1. First, it burns at a surface temperature of nearly 60,000 degrees, far hotter than our Sun’s measly 10,000 degrees. Bortolot, V.J., Jr., 1972: The Interstellar Line Spectra of Zeta Ophiuchi and Zeta Persei and Their Relation to to the Short Wavelength Microwave Background Radiation.Ph.D. Zeta Ophiuchi (ζ Oph, ζ Ophiuchi) is a star located in the constellation of Ophiuchus.It has an apparent visual magnitude of 2.57, [2] making it the third brightest star in the constellation. Zeta Draconis; zeta function; Zeta Geminorum; Zeta Hydrae; Zeta Leonis; Zeta … Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between between 10,000 and 25,000K based on the notes from Harvard University. It is a binary star formed by Alpha Ophiuchi A, and Alpha Ophiuchi B. Garafsa Colour and Temperature . But today, let’s talk about a very interesting star in Ophiuchus the Serpent Bearer, known as Zeta Ophiuchi. Parallax measurements give an estimated distance of roughly 366 light-years (112 parsecs) from the Earth. Zeta Ophiuchi is a young but very big and hot star found roughly 370 light-years or 2,175,091,400,000,000 miles from our home planet. 2. 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. First, it burns at a surface temperature of nearly 60,000 degrees, far hotter than our Sun’s measly 10,000 degrees. WE SHIP WORLDWIDE RIS Citation TY - JOUR ID - sh04500f AU - Shulman, S. AU - Bortolot, V. J. Antares Zeta Ophiuchi Aldebaran Arcturus Vega Sirius A . The star is a fast spinner, with a projected rotational velocity of 138 km/s. Zeta Ophiuchi (ζ Oph, ζ Ophiuchi) is a star located in the constellation of Ophiuchus.It has an apparent visual magnitude of 2.57, making it the third-brightest star in the constellation. 104| Regulus Mira Luminosity (L.)

From its distance and great temperature of 32,500 Kelvin (from which we can account for the star's fierce ultraviolet light), we calculate a magnificent luminosity of 68,000 times that of the Sun, and from that a mass of 20 times solar, the star about in the middle of its short (8 million years) hydrogen-fusing lifetime. It is also considerably larger than the Sun, with 9.03 solar radii. Zeta Ophiuchi is a stellar juggernaut that is thought to have once been part of a binary star system with an even more massive partner.. WikiMatrix WikiMatrix . The projected rotational velocityma… So basically the Sun is a little cooler and younger than Zeta 2 Reticuli. The star centered in this image is Zeta Ophiuchi: a giant, blue star, with 20 times the mass and 80,000 times the brightness of our comparatively weak and humble sun. Agreement NNX16AC86A, Is ADS down? The bow shock, or shock wave, in front of the giant star Zeta Ophiuchi shown in this image from Spitzer is visible only in infrared light. NASA estimates the star is … Key Facts & Summary. The J = 2-1 lines of (C-12)O and (C-13)O have been observed around Zeta Oph at positions corresponding to the earlier J = 1-0 data of Liszt (1992), in order to determine the number density, temperature, and isotopic abundance ratio. For a more massive protostar, the core temperature will eventually reach 10 million kelvin, initiating the proton-proton chain reaction and allowing hydrogen to fuse, first to deuterium and then to helium. The temperature is about 1 million degrees Fahrenheit (600,000 degrees Kelvin). Zeta doesn’t have a common name, just Zeta. Delta Ophiuchi (δ Ophiuchi, abbreviated Delta Oph, δ Oph), formally named Yed Prior / ˌ j ɛ d ˈ p r aɪ ər /, is a star in the constellation of Ophiuchus.It forms a naked-eye optical double with Epsilon Ophiuchi (named Yed Posterior).The apparent visual magnitude is 2.75, making this a third-magnitude star and the fourth-brightest in the constellation.
