Sentences with phrase «planet around a binary star»

Not necessarily, says Harvard astrophysicist Matt Holman, who has used a computer to simulate how a planet around a binary star would behave over millions of orbits.

Astronomers could discover a plethora of planets around binary star systems ¬ - stars that rotate around each other — by measuring with high precision how stars move around each other, looking for disturbances exerted by possible exoplanets.

Kuchner and his colleagues recently reported their findings from the Spitzer Space Telescope, which showed that planets around binary stars can have a rough life.

Not exact matches

The worlds are aptly named «circumbinary planets» («circum» meaning around, and «binary» referring to two objects), and in this type of binary system, the two stars orbit each other while the planet orbits the two stars (pictured above).

In some rare cases, a planet in a binary system may spiral around the axis that connects its two stars — although how such planets come to be is unclear

But those same statistics also indicate that planets are less common around binary stars like Alpha Centauri A and B, and previous studies have largely ruled out large worlds like Jupiter or Neptune there.

The shortest - period binary star system around which a circumbinary planet has been discovered was Kepler 47, with a period of about 7.45 days.

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.

In research published this week in Astrophysical Journal Letters, Dr Zoe Leinhardt and colleagues from Bristol's School of Physics have completed computer simulations of the early stages of planet formation around the binary stars using a sophisticated model that calculates the effect of gravity and physical collisions on and between one million planetary building blocks.

In recent years, evidence has grown that binary star systems can host planets, and observations suggest that planet formation is common around both tight and widely separated binary stars.

During the relatively brief, combined giant phases of the two stars at present, however, a planet could orbit the Aab pair far enough out for the two stars to act as a single gravitational source and near enough for it to receive enough energy to sustain life, possibly around 12.5 AUs out from the binary.

Now that planets are often found around binary stars (an unstable situation), it is clear that the planets are young, and they must have formed at about the same time as their binary stars.

So - called circumbinary planets — those planets that orbit around a binary star, like the fictional Tatooine from the Star Wars — can be ejected off into space as a consequence of their stars» evolution, according to a new study to be published in the Astrophysical Journal (arXiv.org prepristar, like the fictional Tatooine from the Star Wars — can be ejected off into space as a consequence of their stars» evolution, according to a new study to be published in the Astrophysical Journal (arXiv.org prepriStar Wars — can be ejected off into space as a consequence of their stars» evolution, according to a new study to be published in the Astrophysical Journal (arXiv.org preprint).

Adding to the recent spate of planetary finds, astronomers from NASA's Goddard Space Flight Center and San Diego State University (SDSU) announced yesterday they've discovery the largest - known planet to orbit two stars, confirming theories about large planets around binary systems.

This is the largest - ever planet found in orbit around a binary star system, and like our own solar system neighbor, is a gas giant that probably has moons.

The orbit of an Earth - like planet around the tight binary system that star Ba forms with its brown dwarf companion in the liquid water zone would have to be centered around 1.1 AU — a little farther than Earth's orbital distance around Sol — with an orbital period exceeding one Earth year.

On March 29, 2007, astronomers using NASA's infrared Spitzer Space Telescope announced their finding that planetary systems — dusty disks of asteroids, comets, and possibly planets — may be at least as abundant in binary star systems as they are around single stars, like Sol.
