Sentences with phrase «in a close orbit»

It was spinning too quickly, on the other hand, to make the capture of a moon in a close orbit likely.

In contradiction to the long - standing idea that larger planets take longer to form, U.S. astronomers today announced the discovery of a giant planet in close orbit around a star so young that it still retains a disk of circumstellar gas and dust.

One common idea suggested by the public is that a stellar - mass black hole in close orbit around Boyajian's star could block the star's light.

On February 25, 2008, a team of astronomers released a paper on simulation results which support the conclusions of previous studies that multiple - planet systems could have formed in close orbits around both heavy - element rich, Alpha Centauri A and B.

In addition, the lack of any brown dwarfs or gas giants in close orbits around A or B make the likelihood of terrestrial planets greater than otherwise.

This is because their intense magnetic activity interferes with the light emitted by the star to a far greater extent than a potential giant planet, even in a close orbit.

But instead of orbiting sedately, hundreds of millions of kilometres from their stars, the first crop were frantically whirling round in close orbits, blistering in hellish heat.

An artist's rendering shows the planet HD 20782, the most eccentric planet ever known, passing its star in close orbit.

KELT - 9 radiates such intense ultraviolet heat that KELT - 9b, trapped in a close orbit, is doomed.

Pulsar surveys with the SKA will discover tens of thousands of pulsars, amongst which we expect to find a pulsar in orbit around a stellar - mass black hole and pulsars in close orbit around the super-massive black hole at the Galactic Centre.

Binary black holes, as the name suggests, are a system composed of two black holes locked in close orbit around each other.

Because red dwarfs are so cool, planets would have to be parked in close orbit to sustain surface water, and thus be deemed potentially habitable.

With a brown dwarf within a parsec of our own system being a hopeful and still - possible scenario for a more - accessible long - term destination than the Alpha Centauri system, I'd say the idea and hope that there could be something even semi-habitable in close orbit around that brown dwarf is a lot more exciting than just rocks or iceballs.

The goal of this work that I did with Berkeley astronomer Andrew Howard was to measure the fraction of stars that have small planets in close orbits.

On February 25, 2008, a team of astronomers released a paper on simulation results which indicate that multiple - planet systems could have formed in close orbits around both Alpha Centauri A and B.

The two main methods — measuring the wobble of stars caused by the gravitational tug of an orbiting planet and measuring the periodic dimming of a star as a planet passes in front — both favor big planets in close orbits.

Theorists will have to refine their models of planet formation, but will still have to explain how systems like our own ended up with giant planets farther out and small planets in closer orbits.

But if these unseen bullies are there, they may have removed many of the smaller planets in closer orbits, leaving behind the solitary worlds that Kepler sees.

Transit searches, which track the periodic dimming of a star as a planet passes in front of it, more easily detect large planets in close orbits that blot out more light when they eclipse their stars.
