We show that the exoplanet-host star iota Horologii, alias HD 17051, which belongs to the so-called Hyades stream, was formed within the primordial Hyades stellar cluster and has evaporated towards its present location, 40 pc away. Methods. This result has been obtained unambiguously by studying the acoustic oscillations of this star, using the HARPS spectrom- eter in La Silla Observatory (ESO, Chili). Results. Besides the fact that ι Hor belongs to the Hyades stream, we give evidence that it has the same metallicity, helium abun- dance, and age as the other stars of the Hyades cluster. They were formed together, at the same time, in the same primordial cloud. Conclusions. This result has strong implications for theories of stellar formation. It also indicates that the observed overmetallicity of this exoplanet-host star, about twice that of the Sun, is original and not caused by planet accretion during the formation of the planetary system.

  • The Drifting Star: Astronomers 'Listen' to an Exoplanet-Host Star and Find Its Birthplace 15 April 2008
    The drifting star: Astronomers 'listen' to an exoplanet-host star and find its birthplace 15 April 2008 that move in the same direction. Previously, astronomers using an ESO telescope had shown that the star harbours a planet, more than 2 times as large as Jupiter and orbiting in 320 days. But until now, all studies were unable to pinpoint the exact characteristics of the star, and hence to understand its origin. A team of astronomers, led by Sylvie Vauclair from the University of Toulouse, France, therefore decided to use the technique of 'asteroseismology' to unlock the star's secrets. "In the same way as geologists monitor how seismic waves generated by earthquakes propagate through the Earth and learn about the inner structure of our planet, it is possible to study sound waves running through a star, which forms a sort of large, spherical bell," says Vauclair. Using HARPS on ESO's 3.6-m telescope at La Silla, astronomers were able to study in great detail the star The 'ringing' from this giant musical instrument Iota Horologii, known to harbour a giant planet, and provides astronomers with plenty of information make a very precise portrait of it: its temperature is 6150 about the physical conditions in the star's interior. K, its mass is 1.25 times that of the Sun, and its age is 625 million years. Moreover, the star is found to be more And to 'listen to the music', the astronomers used metal-rich than the Sun by about 50%. This means the one of the best instruments available.

Elements with atomic number 6 ≤ Z ≤ 30 have abundances that are in excellent agreement with those of the cluster within the ±0:01 dex (or ' 2 %) precision errors. Heavier elements show a range of abundances such that about half of the Z > 30 species analyzed are consistent with those of the Hyades, while the other half are marginally enhanced by 0:03 ± 0:01 dex (' 7 ± 2 %). The lithium abundance, A(Li), is very low compared to the well-defined A(Li){Teff relation of the cluster. For its Teff , ι Hor's lithium content is about half the Hyades'. Attributing the enhanced lithium depletion to the planet would require a peculiar rotation rate, which we are unable to confirm.

  • Kepler's Laws (ANSWER KEY)
    Name: ____________________________ Date:____________________ Mr. Croom’s Physics Chapter 7: Rotational motion Kepler’s Laws (ANSWER KEY) Solve the following problems 1. (Serway, p. 253, #2) Does a planet in orbit around the sun travel at a constant speed? How do you know? No since the distance from the sun changes. 2. (Serway, p. 253, #3) Suppose you know the mean distance between both Mercury and the sun and Venus and the sun. You also know the period of Venus’s orbit around the sun. How can you find the period of Mercury’s orbit? Keepler’s 3rd Law 3. The planet shown below sweeps out Area 1 in half the time that the planet sweeps out Area 2. How much bigger is Area 2 than Area 1? 2 times as big. 4. (Giancoli, p 142, #55) Halley’s comet orbits the Sun roughly once every 76 years. It comes very close to the surface of the Sun on its closest approach. Estimate the greatest distance of the comet from the Sun. Is it still “in” the Solar System? What planet’s orbit is nearest when it is out there?
