Sentences with phrase «orbital periods near»

Kepler - 18c and Kepler - 18d have orbital periods near a 2:1 mean - motion resonance, leading to large and readily detected transit timing variations.

Not exact matches

Assuming this is the orbital period of hot gas revolving near the black hole, the astronomers deduce that the monster weighs 450,000 to 5 million times more than the sun, agreeing with previous estimates and making the black hole comparable to the 4 - million - solar - mass one at the Milky Way's center — but located in a galaxy 3.9 billion light - years away.

Our new -LCB- \ em Spitzer -RCB- observations were taken two years after the original K2 discovery data and have a significantly higher cadence, allowing us to derive improved estimates for this planet's radius, semi-major axis, and orbital period, which greatly reduce the uncertainty in the prediction of near future transit times for the -LCB- \ em James Webb Space Telescope -RCB--LRB--LCB- \ em JWST -RCB--RRB- observations.

KELT - 9b has an extremely short orbital period, a near - polar orbit and travels around a star that is oblate, not spherical, co-author Karen Collins, a post-doctoral fellow at Vanderbilt, noted.

Planet «b» has 7.5 Earth - masses at an average orbital distance of 0.08 with a period of only 9.5 days and an orbital eccentricity near 0.40.

Lastly, there may be an additional third planet «d,» which may have around 54 percent of Jupiter's mass and an average orbital distance of around 3 AUs with a period of around 6 years (2,172 + / - 158 and an eccentricity near 0.48.

Moreover, we are also nearing the end of this interglacial period, so if anything the orbital component has already flipped back in the direction of glaciation and cooling.

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).

The orbital period of Pluto is 248 years, and so it spends long times near these points — long enough to come to some sort of quasi-equilibrated average temperature.
