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 کاملPlanets of young stars : the TLS radial velocity survey
We report on the search for planets orbiting 46 nearby young stars performed at the State Observatory of Turingia (TLS) by means of a radial velocity survey. The aim of this program is to test the theories of formation/evolution of planetary systems. For 19(8) stars we can exclude planets with M sin i ≥ 1 M J (5 M J) and P ≤ 10 days; we find 1 short period binary and 5 stars with long period RV...
متن کاملA SYSTEM OF THREE PLANETS CONFIRMED BY TRANSIT TIMING VARIATIONS, LIGHTCURVE VALIDATION, Warm-Spitzer PHOTOMETRY AND RADIAL VELOCITY MEASUREMENTS
We report the detection of three transiting planets around a Sunlike star, which we designate Kepler18. The transit signals were detected in photometric data from the Kepler satellite, and were confirmed to arise from planets using a combination of large transit-timing variations, radial-velocity variations, Warm-Spitzer observations, and statistical analysis of false-positive probabilities. Th...
متن کاملRadial Velocity Variations in K Giants: Planets or Pulsations?
Radial velocity observations of K giants have revealed periodic variations for some of the stars. The periods range from approximately 180 to 1000 or more days with velocity amplitudes ranging from approximately 50 m/s to 500 m/s. Except for Iota Draconis (Frink et al. 2002), all variations are nearly sinusoidal. Companions with zero orbital eccentricity as well as pulsations may cause these ra...
متن کاملDetection and characterization of extrasolar planets: the transit method
Exoplanets can be detected by the transit method when the star, planet and observer are aligned. The transits translate into a shallow dip in the stellar light curve. When combined with radial velocity measurements, the transit method permits the determination of a planet’s mass, radius and density. In this chapter we describe the main features of transit light curves, some issues about the met...
