Extrasolar planet taxonomy: a new statistical approach
In this paper we present the guidelines for an extrasolar planet taxonomy. The discovery of an increasing number of extrasolar planets showing a vast variety of planetary parameters, like Keplerian orbital elements and environmental parameters, like stellar masses, spectral types, metallicity etc., prompts the development of a planetary taxonomy. In this work via principal component analysis fo...
متن کاملSpecial issue of Planetary of Space Science Planet Mars II: A new image of Planet Mars
The international workshop ‘‘Planet Mars II’’ which took place at the Centre de Physique in Les Houches (France) on May 23–June 1, 2005, led to vivid and fruitful discussions about the new results which have recently come out of the Mars Global Surveyor, Mars Odyssey, Exploration Rovers and Mars Express space missions. Following the first workshop which took place on April 28–May 9, 2003 (Encre...
متن کاملDynamical Outcomes of Planet–planet Scattering
Observations in the past decade have revealed extrasolar planets with a wide range of semi-major axes and eccentricities. Based on the present understanding of planet formation via core accretion and oligarchic growth, we expect that giant planets often form in closely packed configurations. While the protoplanets are embedded in a protoplanetary nebula, dissipation prevents eccentricity growth...
متن کاملPlanet-planet Scattering in Planetesimal Disks
We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate the dynamics of marginally unstable systems of gas and ice giants both in isolation and when the planets form interior to a planetesimal belt. The unstable isolated systems evolve under planet-planet scattering to yield...
متن کاملOGLE-TR-3: A Possible New Transiting Planet
Recently, 59 low-luminosity object transits were reported from the Optical Gravitational Lensing Experiment (OGLE). Our follow-up low-resolution spectroscopy of 16 candidates provided two objects, OGLE-TR-3 and OGLE-TR-10, which have companions with radii compatible with those of gas-giant planets. Further high-resolution spectroscopy revealed a very low velocity variation (< 500 m s) of the ho...
