  • Common star draws swift attention with unprecedented flare

    ... habitable planets, because the smaller size of these stars makes it much easier to detect smaller orbiting planets using transit and radial-velocity techniques," Osten said.
  • How like Earth are alien planets?

    ... rocky planets like Earth. Now researchers on the High Accuracy Radial Velocity Planet Searcher (HARPS) survey based at the European Southern Observatory in La Silla, Chile, have ...
  • Astronomers find tiny planet orbiting tiny star

    ... Earth-mass planet will be found by microlensing," Bennett said. "But we'll have to be very quick to beat the radial velocity programs and NASA's Kepler mission, which will be launched in early 2009."
  • One in Three Stars May Have "Super"-Earths [News]

    ... rocky planets up to 10 times as massive as our own.Both results come from the HARPS (High Accuracy Radial velocity Planet Searcher) instrument at the European Southern Observatory on ...
  • Brian May, guitarist for rock band Queen, completes Ph.D. thesis following 30-year hiatus

    ... last year from Imperial College London. His PhD thesis A Survey of Radial Velocities in the Zodiacal Dust Cloud has just been co-published by Springer and Canopus Publishing Ltd.
  • Hurricane Ike tracked by ESA's Envisat

    ... . This analysis of the residual Doppler from the radar echoes allows for the retrieval of radial velocities which are used to provide systematically and in Near Real Time a map of the radial ...
  • Pinning down the Milky Way's spin

    ... it can also be used to resolve other complicated cases, where its ability to determine radial velocities - the speed with which something is moving towards or away from us - with phenomenally high ...
  • Solar system's young twin has 2 asteroid belts

    ... the observations nicely. A candidate planet near the innermost ring already has been detected by radial velocity studies. Those studies suggested that it orbited Epsilon Eridani on a highly elliptical ...
  • Students discover unique planet

    ... . It is the hottest star with a planet ever discovered, and it is rotating very fast. The radial velocity method — that was used to discover most extrasolar planets known — is less efficient on stars ...
  • Predicted planet seen -- first since Neptune 162 years ago

    ... -like star 212 light years away. The planet was confirmed in 2007 using a technique called radial velocity, but its image has not been resolved the way the Fomalhaut planet's has. Quillen has worked ...
  • Transit search finds Super-Neptune

    ... other transiting super-Neptune, known as GJ436b, around a different star. It was discovered by a radial velocity search and later found to have transits. "Having two such objects to compare helps ...
  • HARPS-NEF TO Give Kepler A Boost In Finding New Earths

    ... Ian Skillen of the ING will present the new High Accuracy Radial-velocity Planet Search – New Earths Facility (HARPS-NEF) spectrograph in a poster on Monday 20th April at the ...
  • Radio telescope images reveal planet-forming disk orbiting twin suns

    ... technique used so far for the discovery of extrasolar planets - that of measurement of precision radial velocities - is exceedingly difficult for close binary stars such as V4046 Sagittarii. So these ...
  • First solid evidence for a rocky exoplanet

    ... get an answer, astronomers had to call upon the best exoplanet-hunting device in the world, the High Accuracy Radial velocity Planet Searcher (HARPS) spectrograph attached to the ...
  • 32 new exoplanets found

    ... as 3.5 km/hour, a steady walking pace. Such a precision is crucial for the discovery of exoplanets and the radial velocity method, which detects small changes in the radial velocity of a star as it ...
