If the plane of the orbit of the system is very nearly along the line of sight, this provides the most ideal situation for attempting to detect planets using the radial-velocity of the parent star.    From Wordnik.com.  [New Observations of TrES-2b May Reveal New Exoplanet | Universe Today] Reference

One of the most successful ways of detecting extrasolar planets is the radial-velocity method.    From Wordnik.com.  [Daylight Atheism] Reference

This is what will make it easy for radial-velocity measurements to tell a transiting planet from a binary star.    From Wordnik.com.  [Space News From SpaceDaily.Com] Reference

Indeed, all of the candidate planets found by Kepler will be subject to confirmation through radial-velocity studies.    From Wordnik.com.  [Space News From SpaceDaily.Com] Reference

Pamela: They were looking at the radial-velocity changes in the stars 'stellar spectra that were created by the gravitational pull of these different planets on the central star.    From Wordnik.com.  [Astronomy Cast] Reference

The radial-velocity observations were complemented with precise brightness measurements acquired with robotic telescopes in Arizona by Gregory Henry of Tennessee State University.    From Wordnik.com.  [U.S. News] Reference

Responding to the questions raised about Exo-7b's mass, the researchers told me that today's estimate of 11 Earth masses, based on radial-velocity measurements, was merely an upper limit.    From Wordnik.com.  [Cosmic Log] Reference

But there are tantalizing residual motions in its radial-velocity signals that hint at an additional orbiting companion further out in the system, perhaps even in the star's habitable zone.    From Wordnik.com.  [Boing Boing] Reference

At least three planet-hunting teams are currently performing radial-velocity surveys of Alpha Centauri, with a particular focus on B, which is a more quiescent star, and thus easier to monitor.    From Wordnik.com.  [Boing Boing] Reference

The European Southern Observatory's HARPS spectrometer, the world's premier radial-velocity instrument, is closely monitoring HD 40307 in hopes of finding additional, more habitable planets there.    From Wordnik.com.  [Boing Boing] Reference

More than 300 planets have been detected beyond our solar system - but the most commonly used method for detecting them (known as the radial-velocity method) works best with big planets like Jupiter rather than small planets like Earth.    From Wordnik.com.  [Cosmic Log] Reference

There's a catch, though: radial-velocity measurements will work for confirming planets larger than Earth, or Earth-sized planets that orbit close-in to their stars, but they aren't sensitive enough to detect Earth-sized planets in one-year orbits.    From Wordnik.com.  [Space News From SpaceDaily.Com] Reference

It's even further away than GJ 1214, lying 42 light-years distant in the constellation Pictor, but it's of great interest to planet-hunters because of its confirmed planets, radial-velocity technique, meaning that astronomers can only estimate their mass and don't have reliable information on their density or composition.    From Wordnik.com.  [Boing Boing] Reference

51 Pegasi was the star where the first extrasolar world was discovered using radial-velocity methods; astronomers Michel Mayor and Didier Queloz announced the discovery the Jupiter class gas giant on October 12, 1995.    From Wordnik.com.  [Conservapedia - Recent changes [en]] Reference

He added: "If we could build the best possible radial-velocity instrument tomorrow, we might have answers in three years, and a solid census of Earthlike planets within a decade.    From Wordnik.com.  [Daily News & Analysis] Reference
