Sentences with phrase «high photometric»

We also show that K1 - K2 color can be used with YJH low - resolution spectra to identify young L - type companions, provided high photometric accuracy (< 0.05 mag) is achieved.

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.

Piper Michelle Reid, Dripping Springs High School, Dripping Springs, Texas Photometric and Spectroscopic Analysis for the Determination of Physical Parameters of an Eclipsing Binary Star System

Using the high angular resolution of the Keck II telescope, combined with a large number of photometric observations taken since 1957, the team built a refined shape hoping to get a clue to the origin of the system.

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.

In order to identify false positives and confirm transiting exoplanets, we have assembled a follow - up network (KELT - FUN) to conduct imaging with higher spatial resolution, cadence, and photometric precision than the KELT telescopes, as well as spectroscopic observations of the candidate host stars.

Since we do not require spectroscopy or high - resolution imaging for validation, some of our derived parameters for a planetary system may be systematically incorrect due to dilution from light due to additional stars in the photometric aperture.

However, the high luminosity of the primary star, intense Ca II H and K emission (Smith and Dominy, 1979), and radial velocity variations somewhat larger than can be accounted for by the expected uncertainties suggested that Delta Eridani might be an RS CVn - type binary and therefore a photometric variable like most members of that class.

Abstract: Based on more than four weeks of continuous high cadence photometric monitoring of several hundred members of the young cluster NGC 2264 with two space telescopes, NASA's Spitzer and the CNES CoRoT (Convection, Rotation, and planetary Transits), we provide high quality, multi-wavelength light curves for young stellar objects (YSOs) whose optical variability is dominated by short duration flux burs... ▽ More Based on more than four weeks of continuous high cadence photometric monitoring of several hundred members of the young cluster NGC 2264 with two space telescopes, NASA's Spitzer and the CNES CoRoT (Convection, Rotation, and planetary Transits), we provide high quality, multi-wavelength light curves for young stellar objects (YSOs) whose optical variability is dominated by short duration flux bursts, which we infer are due to enhanced mass accretion rates.

By re-observing the photometric transit, we attempt to determine the transit parameters to high precision, and, by spectroscopic observations, to estimate the properties of the host star and determine the mass of the transiting object by means of radial - velocity measurements.

High precision photometric observations were obtained in g», r», i», and z» band simultaneously, using the new GROND detector, mounted on the MPI / ESO 2.2 m telescope at La Silla.
