Sentences with phrase «planetary nature»

But other observations need to confirm the true planetary nature of these candidate events, because the observed dips may also be due to an eclipsing binary star in the background whose light blends with the foreground star studied by Kepler.

We consider the detected binary and planet candidates in the first three extended CoRoT runs, and classify the results of the follow - up observations completed to verify their planetary nature.

Because of these false positives, a sequence of tests - as originally outlined by Alonso et al. (2004)- is employed, beginning with detailed revisions of the detection light - curves, and continuing for surviving candidates with follow - up observations, to either reject them from the list of planetary candidates or to verify their planetary nature.

Detailed light curve analysis with BLENDER validates the planetary nature of Kepler - 421b to > 4 sigmas confidence.

The initial transit signal was identified in KELT - North survey data, and the planetary nature of the occulter was established using a combination of follow - up photometry, high - resolution imaging, high - resolution spectroscopy, and precise radial velocity measurements.

We summarize the evidence for the planetary nature of the Kepler - 61 transit signal, which we conclude is 30,000 times more likely to be due to a planet than a blend scenario.

Here we verify their planetary nature by validating them statistically using the BLENDER technique, which simulates large numbers of false positives and compares the resulting light curves with the Kepler photometry.

Archival and follow - up photometry, the Gaia parallax, radial velocities, Doppler tomography, and adaptive optics imaging were used to confirm the planetary nature of the companion and characterize the system.

Using BLENDER together with constraints from other follow - up observations we are able to rule out all blends for the two deeper signals, and provide independent validation of their planetary nature.

We detected the transit light - curve signature in the course of the TrES multi-site transiting planet survey, and confirmed the planetary nature of the companion via multicolor photometry and precise radial velocity measurements.

AstraLux has provided very sharp images which rule out the presence of a possible companion star in the vicinity of K2 - 229, confirming the planetary nature of the three objects.

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.

The validation of Kepler - 410 (KOI - 42) was complicated due to the presence of a companion star, and the planetary nature of the system was confirmed after analyzing a Spitzer transit observation as well as ground - based follow - up observations.

We report on the results from the radial - velocity follow - up program performed to establish the planetary nature and to characterize the transiting candidates discovered by the space mission CoRoT.
