Sentences with phrase «planetary transit signals»

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.

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.
To pick out those signals associated with actual planets, physics graduate student Roberto Sanchis - Ojeda searched through the set of periodic light curves, looking for frequent smaller dips in the data midway between the planetary transits.
During planetary transits the stars appear a bit dimmer - a signal that EDEN telescopes can often pick up.
The expected Doppler signals are too small to confirm them by demonstrating that their masses are in the planetary regi... ▽ More We present an investigation of twelve candidate transiting planets from Kepler with orbital periods ranging from 34 to 207 days, selected from initial indications that they are small and potentially in the habitable zone (HZ) of their parent stars.
Transit signals detected in 2013 observations indicate that planetary candidate c could be an Earth - sized planet with a year lasting no more than 20.4 days, putting it slightly further out than Bb but still scorchingly close to the star (Demory et al, 2015; and Jacob Aron, New Scientist, March 27, 2015).
Combined with an estimate of the stellar den... ▽ More We present the discovery of the Kepler - 20 planetary system, which we initially identified through the detection of five distinct periodic transit signals in the Kepler light curve of the host star 2MASSJ19104752 +4220194.
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.
This directly affects the determination of the oc... ▽ More The Kepler mission has to date found almost 6,000 planetary transit - like signals, utilizing three years of data for over 170,000 stars at extremely high photometric precision.
Abstract: We present the discovery of the Kepler - 20 planetary system, which we initially identified through the detection of five distinct periodic transit signals in the Kepler light curve of the host star 2MASSJ19104752 +4220194.
We identified the initial transit signal in the KELT - North survey data and established the planetary nature of the companion through precise follow - up photometry, high - resolution spectroscopy, precise radial velocity measurements, and high - resolution adaptive optics imaging.
We combine the estimate of Teff and [Fe / H] with an estimate o... ▽ More We present the discovery of the Kepler - 19 planetary system, which we first identified from a 9.3 - day periodic transit signal in the Kepler photometry.
Abstract: We present the discovery of the Kepler - 19 planetary system, which we first identified from a 9.3 - day periodic transit signal in the Kepler photometry.
We apply a statistical method to show that the likelihood of the planetary interpretation of the transit signals is more than three orders of magnitude larger than that of the alternative hypothesis that the signals result from an eclipsing binary star.
Using the very high precision Kepler photometry, and follow - up observations, our confidence that these signals represent planetary transits is > 99.1 %.
The agreement of these two values lends credence to the planetary interpretation of the transit signal.
