Not discovered a new solar planet similar to Jupiter


21/12/2010

A team of astronomers State of Qatar with a research team at Harvard Center for Astrophysics (CfA) and other agencies, has recently opened a new space world. This "hot Jupiter," now named Qatar-1b, complemented the growing list of space orbiting distant planets.

Researchers exoplanets Qatar while filming in space hunt "flashing" stars that are blacked out a little bit each time orbiting planet creates a "mini-eclipse" by crossing the space in front of the star as seen from Earth. Transit searches like this must be careful and go through thousands of stars to find a small fraction of the detected planets. Sophisticated monitoring and detailed analysis create perfect opportunities for teamwork.

In order to find a new unknown world, Qatar’s wide-angle cameras (located in New Mexico), took pictures of the sky throughout every clear night from the beginning of 2010. Images were then transferred to the UK for analysis there collaborating astronomers at the University of St. Andrews and Leicester, as well as Qatar. This analysis narrowed the field of study of several hundred possible stars.

A research team from Harvard led by Dr. Al Suba (Al Subai), continued to study the most promising candidates, organizing spectroscopic observations with a telescope with a 60-inch diameter at the Observatory Whipple Observatory, located in the state of Arizona. Such observations may remove binary star systems, creating an eclipse, which mimic planetary transit. They also measured the stars dimming more accurately with the 48-inch telescope.

The results have information confirming the existence of a planet now called Qatar-1b, orbitiruyuschey around the orange star type K, the remote 550 light-years from Earth. Qatar-1b is a gas giant, which is 20 percent larger than Jupiter in diameter and 10 percent more massive. The new planet belongs to the family of "hot Jupiters" because it orbitiruet at a distance of 2.2 million miles from its star - removed only six stellar radii. The temperature on the planet is about 2,000 degrees Fahrenheit.

Qatar-1b passes around the orbit of its parent star for every 1.4 days, meaning that its "year" lasts only 34 hours. This creates a presumption that it is closely related to the star, so that one side of the planet always appears with the star. As a result, the planet completes one lap around its axis in 34 hours, three times slower than Jupiter, which makes the circle for the time span of 10 hours.
