The Exoplanet Orbit Database
We present a database of well determined orbital parameters of exoplanets, and their host stars’ properties. This database comprises spectroscopic orbital elements measured for 427 planets orbiting 363 stars from radial velocity and transit measurements as reported in the literature. We have also compiled fundamental transit parameters, stellar parameters, and the method used for the planets di...
متن کاملThe Next Great Exoplanet
What strange new worlds will our next-generation telescopes find? Kevin Heng is an assistant professor of astrophysics at the University of Bern, Switzerland (Twitter: @KevinHeng1). He is a core science team member of the CHEOPS mission and is involved in the PLATO mission. Joshua Winn is associate professor of physics at the Massachusetts Institute of Technology, was a member of the Kepler sci...
متن کاملExoplanet Investigations
Characterizing planets orbiting stars beyond the sun—exoplanets—is one of the scientific frontiers pioneered using Hubble observations. When Webb becomes operational, the current Hubble results will be expanded to an astonishing degree—far more than would be expected based on the increase in aperture. Webb’s sensitivity in the infrared, and especially its infrared spectroscopic capability, will...
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...
متن کاملThe Brown Dwarf - Exoplanet Connection
Brown dwarfs are commonly regarded as easily-observed templates for exoplanet studies, with comparable masses, physical sizes and atmospheric properties. There is indeed considerable overlap in the photospheric temperatures of the coldest brown dwarfs (spectral classes L and T) and the hottest exoplanets. However, the properties and processes associated with brown dwarf and exoplanet atmosphere...
