A team of astronomers has detected signs of forming a new planetary system observations the star HD169142. The work, involving the Higher Council for Scientific Research (CSIC), has been published in two papers in The Astrophysical Journal.
The planets form from disks of gas and dust that revolve around young stars
As explained Experts planets form from disks of gas and dust that revolve around young stars. Once formed the “seed” of the planet –a polvo– small accumulation of this adds materials and produces a groove in the disc with the shape of its orbit.
This transition between the original hard disk and planetary system, to study and still little known, is precisely what scientists have observed the star.
“Although there have been discovered in recent years more than 1,700 exoplanets, only in rare cases has been obtained direct image and has not yet achieved an image of a planet forming,” he pointed CSIC researcher Mayra Osorio. As indicated, “in HD169142 could be on seeing the seeds of gas and dust which later become planets.”
is a young star HD169142 with twice as massive as the Sun and whose disc extends about 37,500 million miles. According to the researchers, the system presents an excellent orientation for the study of planets forming disk as its front looks.
