Two astronomers in South Africa have found evidence of two giant planets orbiting binary star system. The findings were reported at the South African Astronomical Observatory (SAAO).
According to the SAAO, the solar system with two planets and two 'sun' which was discovered by Stephen Potter and Encarni Romero-Colmenero is an example of a planetary system 'very strange'.
"Two stars, one is a white dwarf and the other is a red dwarf, is so close that they only takes a few hours for each mengorbi each other," said the astronomer, as quoted by News24, June 17, 2011.
Planetary systems, the two astronomers said, is oriented with a very strange way, so that from Earth, causing a pair of stars that eclipse each other every time the orbit, when viewed from Earth.
Potter and his colleagues also found that the eclipse does not occur in certain times. Sometimes eclipses come too fast or too slow.
This finding makes them posits that the presence of two giant planets it gives the effect of gravity will cause the star with an irregular orbit. The planets also will slightly affect the gap between these two eclipses.
From the measurements, astronomers managed to make an estimate that the mass of the two planets were at least six and eight times the mass of Jupiter. Both planets also takes 16 and 5 years for that to be orbiting two stars 'sun' is. But unfortunately, the planets were in a great distance to be photographed directly.
In addition, a binary star system planet named UZ For it is also a planetary system that is very inhospitable place to live.
"Because of its proximity, a white dwarf star's gravity constantly stealing material from the surface of the red dwarf star," astronomer. "The flow of this material will hit the white dwarf star and make it a very hot up to temperatures of millions of degrees," he said.
As a result, astronomers said the star system that will flood the planet with an X-ray radiation with a number of very numerous and deadly.
Strange planetary system itself can be found after astronomers observed using the Southern African Large Telescope (SALT) new SAAO's capable of combining data collected by many observatories and satellites within 27 years.
