Sentences with phrase «for planetary objects»

For most of the candidates (85 %), the transit depths measured with Kepler are consistent with the depths measured with Spitzer as expected for planetary objects, while we find that the most discrepant measurements are due to the presence of unresolved stars that dilute the photometry.

Sheppard announced the new object, called V774104, on 10 November at a meeting of the American Astronomical Society's Division for Planetary Sciences, held in National Harbor, Maryland.

However, many others argue that only planemos that directly orbit stars should qualify as planets, preferring to use the terms «planetary body,» «planetary mass object» or «planemo» for similar free - floating objects (as well as planet - size moons).

Occasionally these objects look something like planetary nebulae, as in the case of the Crab Nebula, but they differ from the latter in three ways: (1) the total mass of their gas (they involve a larger mass, essentially all the mass of the exploding star), (2) their kinematics (they are expanding with higher velocities), and (3) their lifetimes (they last for a shorter time as visible nebulae).

The finding of a 3.3 - day stellar rotation period for Star A that is estimated to be very similar to that of its recently discovered planetary companion moving in a very close «torch» orbit suggests that the planetary object may have tidally locked the star (Brogi et al, 2012; and Butler et al, 1997).

KAMUELA, Hawaii — With data collected from the mighty W. M. Keck Observatory, California Institute of Technology (Caltech) astronomer Mike Brown — known as the Pluto killer for discovering a Kuiper - belt object that led to the demotion of Pluto from planetary status — and Kevin Hand from the Jet Propulsion Laboratory (JPL) have found the strongest evidence yet that salty water from the vast liquid ocean beneath Europa's frozen exterior actually makes its way to the surface.

NASA's Planetary Defense Coordination Office is charged with monitoring the paths of asteroids and other objects with orbits that could send them on a crash course with Earth, and planning for response to an actual impact threat.

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.

A new study led by Western University's all - star cosmochemist Audrey Bouvier proves that the Earth and other planetary objects formed in the early years of the Solar System share similar chemical origins — a finding at odds with accepted wisdom held by scientists for decades.
