Sentences with phrase «in photometric data»
The transit signals were detected in photometric data from the Kepler satellite, and were confirmed to arise from planets using a combination of large transit - timing variations, radial - velocity variations, Warm - Spitzer observations, and statistical analysis of false - positive probabilities.

Previous observations of the brown dwarf, published in 2014, provided tentative indications of water clouds based on very limited photometric data.
Wu leads a team that has developed a method to effectively select quasars in the distant universe based on optical and near - infrared photometric data, in particular using data from the Sloan Digital Sky Survey and NASA's Wide - Field Infrared Explorer, or WISE, satellite.
«We built several models of equal quality from the photometric data, but we favored a model made of two lobes since some of the best adaptive optics observations suggest that the Trojan asteroid has a dual structure,» said Josef Durech, co-author and researcher at the Charles University in Prague.
We distill these candidates into sets of 104 validated planets (57 in multi-planet systems), 30 false positives, and 63 remaining candidat... ▽ More We present 197 planet candidates discovered using data from the first year of the NASA K2 mission (Campaigns 0 - 4), along with the results of an intensive program of photometric analyses, stellar spectroscopy, high - resolution imaging, and statistical validation.

We present new mass measurements of three of the planets in the Kepler - 20 system facilitated by 104 radial velocity measurements from the HARPS - N spectrograph and 30 archival Keck / HIRES observations, as well as an updated photometric analysis of the Kepler data and an asteroseismic analysis of the host star (MStar = 0.948 + -0.051 Msun and Rstar = 0.964 + -0.018 Rsun).
Recent progress has been made to address this: (1) the discovery that gamma Cas is an eccentric binary system (P = 203.59 d) with unknown secondary type, (2) the accumulation of RXTE data at 9 epochs in 1996 - 2000, and (3) the collation of robotic telescope B, V - band photometric observations over 4 seasons.
Due to the availability of data from three observing runs separated by ~ 10 and 1 month timescales, we are able to demonstrate clear evidence for evolution of the photometric amplitudes, and hence spot patterns, over the 10 month gap, although we are not able to constrain the timescales for these effects in detail due to limitations imposed by the large gaps in our sampling, preventing use of the phase information.
The plethora of photometric, spectroscopic, asteroseismic and astrometric data allows us to characterise the comprising stars in detail.
Abstract: We studied solar - like oscillations in 115 red giants in the three open clusters NGC 6791, NGC 6811, and NGC 6819, based on photometric data covering more than 19 months with NASA's Kepler space telescope.
