Binary star

For the first time, researchers have detected a streamer of gas flowing from a massive outer disc toward the inner reaches of a binary star system. This never-before-seen feature may be responsible for sustaining a second, smaller disc of planet-forming material that otherwise would have disappeared long ago. Half of Sun-like stars are born in binary systems, meaning that these findings will have major consequences for the hunt for exoplanets. (ESO)

OGLE-2013-BLG-0341LBB THE PLANET SHOWS HOW HABITABLE PLANETS COULD POSSIBLY BE LOCATED IN A BINARY STAR SYSTEM. THE PLANET ORBITS ONE OF TWO STARS IN A BINARY STAR SYSTEM AT THE SAME DISTANCE FROM WHICH THE EARTH ORBITS THE SUN.   THE PLANET'S STAR IS MUCH DIMMER THAN OUR SUN AND DOES NOT PRODUCE A LOT OF HEAT, SO THE PLANET ITSELF IS NOT HABITABLE. HOWEVER, SCIENTISTS SAY THIS DEMONSTRATES THAT ROCKY PLANETS CAN FORM IN EARTH-LIKE ORBITS EVEN WHEN THERE ARE TWO STARS INVOLVED.

Binary stars are two stars orbiting a common center of mass. More than four-fifths of the single points of light we observe in the night sky are actually two or more stars orbiting together.

A Catholic Citizen in America: Enceladus and Kepler's Planets

NASA astronomers recently discovered a frozen world that orbits a binary star system 3,000 lightyears from Earth. The planet is even colder than Jupiter's icy moon Europa.

Newfound Frozen World Orbits in Binary Star System

An artist's rending of a newly discovered planet in a binary, or twin, star system located light-years from Earth.

Esta nueva visión ricamente detallado del telescopio MPG / ESO de 2,2 metros en el Observatorio La Silla, en Chile muestra la región de formación estelar de la goma 15. Este objeto poco conocido se encuentra en la constelación de Vela (las velas), algunos 3000 light- años de la Tierra. La nube resplandeciente es un impresionante ejemplo de una región HII. También tiene una similitud con una más famosa región HII, la Nebulosa Trífida (Messier 20).

Discovery expands search for Earth-like planets: Newly spotted frozen world orbits in a binary star system

Crescent-Shaped Planet-Forming Cloud --"The Result of Gravitational Forces Unique to Binary Stars?"

Using the largest radio telescope in the world, the Atacama Large Millimeter-submillimeter Array (ALMA), astronomers have uncovered new details about the early stages of planet formation around a b.

UK Infrared Telescope discovers "impossible" binary stars | Astronomy.com

Scientists found several red dwarf binaries with orbital periods significantly shorter than the five-hour cut-off found for Sun-like stars, something previously thought to be impossible.

New hypervelocity binary star challenges dark matter, stellar acceleration models

The recent discovery of a hyper-velocity binary star system in the halo of the Milky Way poses a mystery: how was this system accelerated to its high speed?

Oh, this is too cool: scientists have found a planet orbiting a binary star (a pair of stars in tight orbit around each other) that is at the right distance to have liquid water! Let me be clear: this planet is much bigger than Earth, and is likely to be a gas giant. So it’s not Earth-like, and probably not itself habitable.     But it might have moons…

This artist's concept illustrates the first transiting circumbinary system — multiple planets orbiting two suns — light-years from Earth, in the constellation Cygnus.

Image of the Day: Strange Merging Binary Stars Discovered --Four Hour Orbits!  A team of astronomers have used the United Kingdom Infrared Telescope (UKIRT) on Hawaii to discover four pairs of stars that orbit each other in less than 4 hours. Until now it was thought that such close-in binary stars could not exist. The new discoveries come from the telescope's Wide Field Camera (WFCAM) Transit Survey, and appear in the journal Monthly Notices of the Royal Astronomical Society.
