Sentences with phrase «planetary candidates for»

That pace promises to increase as NASA's Kepler mission carries out its multiyear survey of a large patch of stars; the campaign has already located several hundred planetary candidates for follow - up study and confirmation.

Following the Kepler space telescope's discovery of more than 5,000 possible exoplanets since 2009, TESS will continue the galactic census — flagging more planetary candidates for further study.

Not exact matches

In the agency's latest competition for future Discovery missions — its line of low - cost planetary probes — two out of five final candidates targeted Venus, including a mission Glaze would have led.

Possible candidates for robotic planetary exploration missions include Venus, Mars, asteroids, comets and Titan

According to planetary geologist Ronald Greeley, «Jupiter's moon Europa, along with Mars and Saturn's moon Titan, tops the list of likely candidates for life.»

«This star is a not a good candidate for direct imaging of planets, but it demonstrates what LBTI is good for: We are figuring out the architecture of planetary systems in a way that has not been done before.»

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.

We compare the transit duration distribution for different subsets of Kepler planet candidates and discuss tentative trends with planetary radius and multiplicity.

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 photometFor 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 photometfor planetary objects, while we find that the most discrepant measurements are due to the presence of unresolved stars that dilute the photometry.

Characterizing K2 Candidate Planetary Systems Orbiting Low - Mass Stars III: A High Mass & Low Envelope Fraction for the Warm Neptune K2 - 55b

Since a planet's radius and equilibrium temperature depends on the parameters of its host star, our study provides more precise planetary parameters for planets and candidates orbiting late - type stars observed with K2.

Abstract: We present near - infrared spectra for 144 candidate planetary systems identified during Campaigns 1 - 7 of the NASA K2 Mission.

Planets that are regularly swapped between their stars may be unlikely candidates for habitability, but the more compact a planetary system, the less likely a planet will be stolen by a passing star.

Follow - up observations of planetary candidates identified by detection of transit - like events are needed both for identification of astrophysical phenomena that mimic planetary transits and for characterization of the... ▽ More The Kepler Mission was launched on March 6, 2009 to perform a photometric survey of more than 100,000 dwarf stars to search for terrestrial - size planets with the transit technique.

Follow - up observations of planetary candidates identified by detection of transit - like events are needed both for identification of astrophysical phenomena that mimic planetary transits and for characterization of the true planets and planetary systems found by Kepler.

For each planetary candidate, the equilibrium surface temperatures are derived from «grey - body spheres without atmospheres... [and] calculations assume a Bond albedo of 0.3, emissivity of 0.9, and a uniform surface temperature... [with uncertainties of] approximately 22 %... because of uncertainties in the stellar size, mass, and temperature as well as the planetary albedo.»

Thus far, Kepler has found 48 planetary candidates in their host star's habitable zone (of which 10 are near Earth - size), but this number is a decrease from the 54 reported in February 2011 only because the Kepler team is now applying a stricter definition of what constitutes a habitable zone around stars to account for the warming effect of planetary atmospheres, which would move such a zone away from the star, outwards in orbital distance resulting in longer orbital periods (NASA news release; and Kepler Press Conference slides — in pdf).

These lanes channel each player to fight for a central planetary system that's an ideal candidate for base building.
