TIRAVEL - Template Independent RAdial VELocity measurement
We propose a new approach to measure differential radial velocities, mainly for single-lined spectroscopic binaries. The proposed procedure – TIRAVEL (Template Independent RAdial VELocities) – does not rely on a prior theoretical or observed template, but instead looks for a set of relative Doppler shifts that simultaneously optimizes the alignment of all the observed spectra. We suggest a simp...
متن کاملKeck Measurement of the Xte J2123–058 Radial Velocity Curve
We measured the radial velocity curve of the companion of the neutron star X-ray transient XTE J2123–058. Its semi-amplitude (K2) of 298.5±6.9 km s−1 is the highest value that has been measured for any neutron star LMXB. The high value for K2 is, in part, due to the high binary inclination of the system but may also indicate a high neutron star mass. The mass function ( f2) of 0.684± 0.047M⊙, a...
متن کاملRadial 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 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 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...
