Radial Velocity
The radial velocity technique was utilized to make the first exoplanet discoveries and continues to play a major role in the discovery and characterization of exoplanetary systems. In this chapter we describe how the technique works, and the current precision and limitations. We then review its major successes in the field of exoplanets. With more than 250 planet detections, it is the most prol...
متن کاملRAVE: The RAdial Velocity Experiment
RAVE (RAdial Velocity Experiment) is an ambitious program to conduct an all-sky survey (complete to V = 16) to measure the radial velocities, metallicities and abundance ratios of 50 million stars using the 1.2-m UK Schmidt Telescope of the Anglo-Australian Observatory (AAO), together with a northern counterpart, over the period 2006 2010. The survey will represent a giant leap forward in our u...
متن کامل3D velocity from 3D Doppler radial velocity
We present local least squares and regularization frameworks for computing 3D velocity (3D optical flow) from 3D radial velocity measured by a Doppler radar. We demonstrate the performance of our algorithms quantitatively on synthetic radial velocity data and qualitatively on real radial velocity data, obtained from the Doppler radar at Kurnell Radar station, Botany Bay, New South Wales, Austra...
متن کاملThe Visual Orbit of • Pegasi
We have determined the visual orbit for the spectroscopic binary • Pegasi with interferometric visibility data obtained by the Palomar Testbed Interferometer in 1997. • Peg is a double-lined binary system whose minimum masses and spectral typing suggests the possibility of eclipses. Our orbital and component diameter determinations do not favor the eclipse hypothesis : the limb-to-limb separati...
متن کاملThe Planet around 51 Pegasi
Doppler measurements of 51 Pegasi have been made from 1995 October through 1996 August, with a precision of 5 m s~1. We Ðnd a period of 4.231 days, a velocity amplitude of 56^ 1 m s~1, and a velocity curve that is essentially sinusoidal, all in excellent agreement with Mayor & Queloz. The only viable interpretation is a companion having minimum mass, m sin i \ 0.45 in a circular orbit of MJupit...
