how old is zeta puppis

The dwarf is one of the hottest stars known, with a surface temperature of 74,700 degrees Celsius (75,000 K). It has the stellar classification O4If, which means that it is an exceptionally hot blue supergiant star. A distance of 800pc requires an abnormally high luminosity, while the Vela OB2 association is much older than Zeta Puppis and the space velocity does not lead back to that cluster. It has an apparent magnitude of 4.50. It is 10 arc seconds in size and can be seen with a small telescope. It lies at an approximate distance of 1,080 light years from Earth. Naos (Zeta Puppis) is a blue supergiant star that can be located in the constellation of Puppis. It is approximately 12,570 light years distant from Earth and has an apparent magnitude of 6.9. 3 Puppis is a binary star with a visual magnitude of 3.93. NGC 2509 is another open cluster in Puppis. Zeta Puppis Model similar to that of 1E0102 .2-7219 Derived from combined RGS spectra of 13 observations (+EPIC-pn for higher energies) Fit to pn spectra: only constant factor allowed to vary gain fit with slope==1.0 and shift as fit parameter RGS1 663.6 ks RGS2 668.8 ks N VI f 420 eV N VI i 426 eV N VI r 431 eV N VII Lyα 500 eV NGC 2440 lies about 4,000 light-years from Earth in the direction of the constellation Puppis. Neither Puppis nor Vela have stars designated Alpha and Beta, as these stars were allocated to Carina constellation. It is the second brightest such star in terms of its apparent magnitude, with only Zeta Orionis appearing brighter. Zeta Puppis, image: Alberto ECJ at wikipedia.org. It is 22 times more luminous than the Sun. Zeta Puppis has been extensively studied because of its rareness and relative closeness to Earth, but its physical parameters and distance are still poorly known. It has the stellar classification of K1.5II+ and is approximately 352 light years distant. Image Credit : ESO – Messier 46 (NGC 2437) is a 300 million years old open cluster situated around 5,500 light years away. The stars have an orbital period of 1.45 days. It appears superimposed on the cluster Messier 46, but the two objects are most likely unrelated as they do not share a common radial velocity. Image: NASA, ESA, K. Noll. Search. Many physical models and the original Hipparcos parallax measurements did lead to a distance value of around 450pc, but the revised Hipparcos reduction gave a much lower distance near 333pc. “Imagine an object about sixty times the mass of the Sun, travelling about sixty times faster than a speeding bullet” the investigators say. Zeta Orionis, also known by the more traditional name, Alnitak, is a triple star system in the constellation of Orion.One of the brightest stars in the night sky, it has an apparent magnitude of 1.70. Sigma Puppis is another spectroscopic binary star in Puppis. Rho Puppis is believed to be about 2 billion years old. QW Puppis has the stellar classification F3VFe-1.0 and is about 70 light years distant from the solar system. Publications Publications List of galaxies (5,731 words) [view diff] exact match in … In fact it is one of the brightest O stars (O5) in the sky, class O being the … Pi Puppis is an orange giant, while Rho and Tau Puppis are both yellow giants. Zeta Puppis is special however, because it is a single massive star, moving through space alone, at a velocity of about 60 kilometers per second. Messier 47 is another open cluster in Puppis, about a degree west of Messier 46. Zeta Puppis has a surface temperature of 42,000 K and a mass 22.5 times that of the Sun. The two stars orbit each other with a period of 1,066.0 days, or 2.9 years. Its surface temperature is over 42,000K, and including radiation at all frequencies, it is perhaps as much as 360,000 times more … Zeta Puppis is an evolved massive star known as a “supergiant.” It is about 60 times more massive than our sun, and seven times hotter at the surface. A debris disk was discovered orbiting the star in 2005, and three extrasolar planets were confirmed to be orbiting the star in 2006. It has the stellar classification of B2V+. He is a wonderful blend of show and old foundation working lines known for excelling as therapy and service dogs. The cluster is believed to be about 10 million years old. It has an apparent magnitude of 4.450 and is about 83.8 light years distant from the Sun. The colors correspond to material expelled by the star. Search form. The star is classified as a Gamma Doradus type variable, which means that it is a young variable star that exhibits variations in luminosity as a result of non-radial pulsations of its surface. Other articles where Zeta Puppis is discussed: star: Stellar atmospheres: , Zeta Puppis), strong, relatively narrow emission lines can be seen; however, in the ultraviolet, observations from rockets and spacecraft show strong emission lines with distinct absorption components on the shorter wavelength side. A recent dynamical study points to Zeta Puppis originating in the Trumpler 10 OB association at around 300pc, but this is also a much older cluster and physical models still lead to a distance of 450-600pc. The inner planet has 3.15 Jupiter masses and an orbital period of 201.83 days, and the outer one has 7.46 times Jupiter’s mass and completes an orbit around the star every 607.06 days. At the dim end of second magnitude (2.25), Naos seems to be just one more star scattered below the Larger Dog. Search . It was discovered by Giovanni Batista Hodierna in 1654. It has an extended halo and the central star is a white dwarf with a visual magnitude of 17.7. Tau Puppis is a spectroscopic binary star system with an apparent magnitude of 2.95. Zeta (ζ) Puppis, Naos, is a star on the deck of Argo Navis the Ship, in the constellation of the Stern. [6], Zeta Puppis shows a high space velocity and very high rotation rate, and it has been speculated that it is a runaway star resulting from a supernova in a binary system, possibly the progenitor of the Gum Nebula[22] but evidence supporting this is sparse. The spectral class of O4 means this is one of the hottest, and most luminous, stars visible to the naked eye.
