PH1: exoplanet discovered in a four suns

PH1: exoplanet discovered in a four suns

A group of amateur astronomers to web planethunters.org with a team of researchers from Britain and the United States has with PH1, on the first exoplanet orbiting two stars, twin suns, which in turn orbit about a second pair of distant stars. A world where the sky is lit by four suns different.

As we say, the discovery has had starring leading a group of volunteers website Planethunters.org and researchers from the Keck Observatory in a paper that has been published recently.

an exoplanet would be located less than 5,000 light years away, a gas giant slightly larger dimensions than those of Neptune and up to six times the size of Earth. According to Chris Lintott, one of the researchers involved in the University of Oxford:

We really should not go too far back before having chance to find one of these systems. The four stars on the planet seem to create a complicated environment in a seemingly stable orbit. This is really confusing and what makes it exciting discovery. Not at all what you would expect.

And is that binary stars, systems with pairs of stars orbiting each other around a common center of mass, are not unusual. Still, only a handful of known are binary stars and none of them are known to have another pair of stars orbiting about them as in this case. According Lintott:

We know there are six planets around binary stars and are all close to those stars. This seems to say that planets can form in the inner parts of protoplanetary disks.

PH1 was initially discovered by Jek Kian (San Francisco) and Gagliano Robert (Arizona), both volunteers in the United States using the web Planethunters.org. They found that there was a slight drop in light caused by a planet passing in front of their parent stars. The report went on to be corroborated both by professional astronomers using the Keck telescopes on Mauna Kea (Hawaii).

A project Planethunters.org where visitors have access to the data collected by the Kepler space telescope at NASA. A website which has involved more than 170,000 fans in the project since December 2010.
