The next generation planet hunter is here!
... rocky planet!” explains lead scientist for ESPRESSO, Francesco Pepe from the University of Geneva in Switzerland. The radial velocity method allows astronomers to measure the mass and orbit of any residing exoplanet and it works by measuring the...

Exoplanet census promises radical discoveries
.... The prevalence of these known short period exoplanets is just a selection effect of transit and Doppler radial velocity methods, because both these methods are much more sensitive to the planets in short period orbits. Another approach is needed...

How to Build Planets
... its host star’s spectral lines, caused by the planet’s gravitational effects as it orbited the star. This method, known as the radial velocity method, is one of three main ‘indirect’ techniques used to detect planets, the others being the astrometry...

Astronomers find system with six planets
... and 0.38 (compared with Jupiter) respectively. All of the planets were found via the radial-velocity method. This method is often to referred to as the ‘wobble’ method and put (very) basically, it involves looking at the change in light that occurs...

Astronomers may have detected the first planet outside of the Milky Way
..., just doesn’t work the same when trying to spot extragalactic exoplanets. The radial-velocity method for finding exoplanets, or wobble method as it is also known by, relies on detecting minute changes in a star’s orbit caused by the gravitational...

Exoplanets galore and possibly the next Trappist-1 system?
... the exoplanets. HARPS itself stands for the High Accuracy Radial Velocity Planet Searcher and it is through the radial velocity method – also known as the watching the wobble method – that these exoplanets were identified. Put basically, a host star...
