A newly discovered alien planet is very special because it orbits a dying star. This planet sought because it can help astronomers study the process of destruction of the planet. It will open a new knowledge about the process of time in the solar system.
The types alien planet palnet gas and six times the size of Jupiter. It orbits a red giant star called HD 102272, which is in the constellation Leo, 1200 light years away (one light year equals 9.5 trillion kilometers). In this star had already been discovered yet another planet orbiting at larger distances.
The stars are small and medium enterprises as the Sun is believed to be gradually transformed into a red giant star, such as reducing emissions from nuclear power releases. Once exhausted the hydrogen is released, the core of the star will expand and begin to burn helium. Part permukannya will swell to 100 times their original size. Since changes of gift so far, and a number of planet Earth may have been destroyed.
"When red-giant stars expand, they will devour planets nearby," said Alexander Wolszczan, an astrophysicist at the University of Pennsylvania who recorded the new planet with the Hobby-Eberly Telescope in McDonals Observatory, Texas, USA. He and his team used techniques for monitoring the fluctuation of light when planets transit, or cross in front of its star.
The newly discovered planet is just 0.6 AU (1 astronomical unit equals the Sun-Earth distance). This is the closest distance of a planet with a red giant star ever recorded so far. Own new star 10 times the size of the Sun and will continue to expand to 100 times.
"The planet itself orbits not in a vacuum, but exhaled gas shocks stellar. Thus decreased energy to orbit the friction with the atmosphere of gas and eventually began to sway in spiral motion," said Wolszczan. How to stop the planet's history, said Wolszczan probably will not happen in 100 million years. The sun itself takes 5 billion years to turn into a red giant star.
