Key Facts & Summary. Zeta doesn’t have a common name, just Zeta. First, it burns at a surface temperature of nearly 60,000 degrees, far hotter than our Sun’s measly 10,000 degrees. First, it burns at a surface temperature of nearly 60,000 degrees, far hotter than our Sun’s measly 10,000 degrees. 5. Rasalhague is located at around 48.6 light-years / 14.9 parsecs away from the Sun. ζ Ophiuchi is an enormous star with more than 19 times the Sun’s mass and eight times its radius. Lambda Ophiuchi B has the stellar classification A4V. The star Zeta Ophiuchi, about 370 light-years from Earth, is rocketing through space at nearly 90,000 kilometers per hour. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative The many different colors of stars reflect the star’s temperature. Satellite observations of transitions of C2 at 2312 Angstroms in the spectrum of Xi Ophiuchi were carried out to evaluate the kinetic temperature of the interior cloud. The surface temperature of our central star (roughly 6,000 degrees Celsius) is responsible for the production of the white "visible" light that reaches Earth. The effective temperature of the outer atmosphere of Delta Ophiuchi is a relatively cool 3,679 K, which is what gives it the orange-red hue of an M-type star. 104| Regulus Mira Luminosity (L.) Betelgeuse Al Orionis C . A relation between the CH and CN molecular line widths in the Zeta Oph cloud is suggested. The projected rotational velocityma… Zeta Ophiuchi is actually a very massive, hot, bright blue star plowing its way through a large cloud of interstellar dust and gas. 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. Antares Zeta Ophiuchi Aldebaran Arcturus Vega Sirius A . Garafsa Luminosity Choices 1 and 3 are both problems for this star as host to a habitable planetary system 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. The simple construction permits a rapid determination of the flow potential or zeta potential. The star AE Aurigae is a young, newly-formed star with quite a lot in common with the star Zeta Ophiuchi. The star has a B-V Colour Index of 0.03 which means the star's temperature is about 9,140 Kelvin. The bow shock is created by winds that flow from the star, making ripples in the surrounding dust. With a surface temperature of 8,831 K, it shines with about 76 solar luminosities. This week on Looking Up Hal reveals an 'inconvenient truth'. [1]Properties. Examples of blue stars include 10 Lacertae, AE Aurigae, Delta Circini, V560 Carinae, Mu Columbae, Sigma Orionis, Theta1 Orionis C, Zeta Ophiuchi… All objects in the universe emit thermal radiation.

Zeta Ophiuchi is a magnificent blue-white O star that is the third brightest star in the constellation Ophiuchus. 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.
