Constraining Orbital Parameters through Planetary Transit Monitoring
The orbital parameters of extra-solar planets have a significant impact on the probability that the planet will transit the host star. This was recently demonstrated by the transit detection of HD 17156b whose favourable eccentricity and argument of periastron dramatically increased its transit likelihood. We present a study which provides a quantitative analysis of how these two orbital parame...
متن کاملRefined stellar, orbital and planetary parameters of the eccentric HAT-P-2 planetary system
We present refined parameters for the extrasolar planetary system HAT-P-2 (also known as HD 147506), based on new radial velocity and photometric data. HAT-P-2b is a transiting extrasolar planet that exhibits an eccentric orbit. We present a detailed analysis of the planetary and stellar parameters, yielding consistent results for the mass and radius of the star, better constraints on the orbit...
متن کاملOrbital Resonances in Planetary Systems
There are two main types of resonance phenomena in planetary systems involving orbital motions: (i) mean motion resonance: This is intuitively the most obvious type of resonance; it occurs when the orbital periods of two planets are close to a ratio of small integers; (ii) secular resonance: this is a commensurability of the frequencies of precession of the orientation of orbits, as described b...
متن کاملAnalytic Light Curves for Planetary Transit Searches
We present exact analytic formulae for the eclipse of a star described by quadratic or nonlinear limb darkening. In the limit that the planet radius is less than a tenth of the stellar radius, we show that the exact light curve can be well approximated by assuming the region of the star blocked by the planet has constant surface brightness. We apply these results to the Hubble Space Telescope o...
متن کاملMeasuring accurate transit parameters
By observing the transits of exoplanets, one may determine many fundamental system parameters. I review current techniques and results for the parameters that can be measured with the greatest precision, specifically, the transit times, the planetary mass and radius, and the projected spin-orbit angle.
