Detectability of Extrasolar Planets in Radial Velocity Surveys
Radial velocity surveys are beginning to reach the time baselines required to detect Jupiter analogs, as well as sub-Saturn mass planets in close orbits. Therefore it is important to understand the sensitivity of these surveys at long periods and low amplitudes. In this paper, I derive analytic expressions for the detectability of planets at both short and long periods, for circular and eccentr...
متن کاملRadial Velocity Detectability of Low Mass Extrasolar Planets in Close Orbits
Detection of Jupiter mass companions to nearby solar type stars with precise radial velocity measurements is now routine, and Doppler surveys are moving towards lower velocity amplitudes. The detection of several Neptune-mass planets with orbital periods less than a week has been reported. The drive toward the search for close-in Earth-mass planets is on the agenda. Successful detection or mean...
متن کاملDetectability of Exoplanetary Transits from Radial Velocity Surveys
Of the known transiting extra-solar planets, a few have been detected through photometric follow-up observations of radial velocity planets. Perhaps the best known of these is the transiting exoplanet HD 209458b. For hot Jupiters (periods less than ∼ 5 days), the a priori information that 10% of these planets will transit their parent star due to the geometric transit probability leads to an es...
متن کاملTransit Detectability of Ring Systems Around Extrasolar Giant Planets
We investigate whether rings around extrasolar planets could be detected from those planets’ transit lightcurves. To this end we develop a basic theoretical framework for calculating and interpreting the lightcurves of ringed planet transits based on the existing framework used for stellar occultations, a technique which has been effective for discovering and probing ring systems in the solar s...
متن کاملExtrasolar planets and brown dwarfs around A - F type stars ⋆ I . Performances of radial velocity measurements
We present the performances of a radial velocity measurement method that we developed for A-F type stars. These perfomances are evaluated through an extensive set of simulations, together with actual radial velocity observations of such stars using the ELODIE and HARPS spectrographs. We report the case of stars constant in radial velocity, the example of a binary detection on HD 48097 (an A2V s...
