Sentences with phrase «shorter orbital periods»

Eventually, this causes celestial bodies to lose orbital energy, and they will have shorter orbital periods of only a few days.»

That, combined with the planets» shorter orbital periods, makes the modeling effort much tougher.

The goal for Winn and his colleagues was to look for Earth - sized planets with very short orbital periods.

Researchers have discovered an Earth - sized exoplanet named Kepler 78b that whips around its host star in a mere 8.5 hours — one of the shortest orbital periods ever detected.

Researchers at MIT have discovered an Earth - sized exoplanet named Kepler 78b that whips around its host star in a mere 8.5 hours — one of the shortest orbital periods ever detected.

The short orbital periods of the newfound planets enabled their detection from the small data set — each planet passed its star several times in the 43 - day observation window, dimming the starlight by a small fraction with each orbit.

In these cases, astronomers can reliably determine their short orbital periods, ranging from hours to days to a couple years.

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.

Abstract: We describe the discovery of a massive transiting hot Jupiter with a very short orbital period (1.30619 d), which we name TrES - 3.

Because K2 - 39b has a short orbital period, its existence makes it seem unlikely that tidal destruction is wholly responsible for the differences in planet populations around subgiant and main - sequence stars.

Not exact matches

The co-authors suggest that future studies looking to find and study possibly habitable planets around short - term binary stars should focus on those with longer orbital periods than about 7.5 days.

Those originating in the Kuiper belt have orbital periods shorter than 200 years.

The different Q values also allow the planets to re-align their orbits with the spin of the star (so that the orbital plane is perpendicular to the star's spin axis) on a timescale shorter than the orbital period decay, thus explaining why there are many «aligned» hot Jupiters.

«Simply put, if the black hole is small, the orbital periods at the innermost circular orbit are shorter, but if the black hole is big, the orbital periods are longer (smaller frequencies).»

Periods of volcanism can cool the climate (as with the 1991 Pinatubo eruption), methane emissions from increased biological activity can warm the climate, and slight changes in solar output and orbital variations can all have climate effects which are much shorter in duration than the ice age cycles, ranging from less than a decade to a thousand years in duration (the Younger Dryas).

The findings help explain why astronomers have detected few circumbinary exoplanets despite observing thousands of short - term binary stars, or ones with orbital periods of 10 days or less.

Halley's Comet is a short orbital - period comet that can be seen from Earth every 75 to 76 years.

Triton is a moon in a close retrograde orbit, data is very sparse, its «year» around Neptune is short, but Neptune's orbital period is longer than we have known about Triton, so again no data on long term secular trends.

Short term solar cycles of the 27 day rotation periods, due to the polarity shifts in magnetic flux changes in the solar wind, The moon has a North / South declinational component as part of it's set of orbital parameters.
