The exoplanet eccentricity distribution from Kepler planet candidates
The eccentricity distribution of exoplanets is known from radial velocity surveys to be divergent from circular orbits beyond 0.1 au. This is particularly the case for large planets where the radial velocity technique is most sensitive. The eccentricity of planetary orbits can have a large effect on the transit probability and subsequently the planet yield of transit surveys. The Kepler mission...

متن کاملExoplanet orbital eccentricity: multiplicity relation and the Solar System.
The known population of exoplanets exhibits a much wider range of orbital eccentricities than Solar System planets and has a much higher average eccentricity. These facts have been widely interpreted to indicate that the Solar System is an atypical member of the overall population of planetary systems. We report here on a strong anticorrelation of orbital eccentricity with multiplicity (number ...
متن کاملLunar Occultations of Stars with Exoplanet Candidates
We investigate the potential of lunar occultations for the detection of very faint companions, and in particular for the possibility of detecting extrasolar planets. We review the basic concepts of the method, and discuss the quantities which are relevant for this particular application. The near-infrared range, and in particular the K and L bands (2.2 and 3.6m), ooer the best dynamic range. We...
متن کاملThe distribution of exoplanet masses
An abstract should be given he present study derives the distribution of secondary massesM2 for the 67 exoplanets and very low-mass brown dwarfs companions of solar-type stars, known as of April 4, 2001. This distribution is related to the distribution of M2 sin i through an integral equation of Abel’s type. Although a formal solution exists for this equation, it is known to be ill-behaved, and...
