Sentences with phrase «false planetary transits»

Not exact matches

The Vespa technique works by comparing the details of a transiting planet signal — specifically its duration, depth and shape — against simulated planetary and false positive signals to indicate the type of signal the candidate most likely is.

This observational result, which uses the achromatic property of planetary transit signals that is not investigated by the Kepler observations, provides an independent indication that Kepler's false positive rate is low.

Major sources of astrophysical false positives are planetary transits and stellar eclipses on background... ▽ More The Kepler Mission was launched on March 6, 2009 to perform a photometric survey of more than 100,000 dwarf stars to search for Earth - size planets with the transit technique.

Giant transiting exoplanets are easily mimicked by false positives, so spectroscopic follow - up observations are needed to establish the planetary nature of the transit detections, and easily reveal blended multiple stellar systems.
