A piece of a planet that has survived the termination of its star has been found by astronomers from the University of Warwick. Reportedly, this piece of a planet was noted in a disc of debris formed from demolished planets, which the star eventually consumes. The nickel- and iron-rich planetesimal survived a system-wide cataclysm, which followed the termination of SDSS J122859.93+104032.9, its host star. Once supposed to have been a portion of a bigger planet, its survival is said to be more surprising as it orbits nearer to its star than earlier thought possible, moving around it once every 2 Hours.
The latest discovery is reported in the journal Science. It is said to be for the foremost time that researchers have employed spectroscopy to find a solid body in orbit around a white dwarf. Researchers employed slight variations in the emitted light to spot extra gas that the planetesimal is generating.
On a similar note, astronomers’ team headed by a Texas-based undergraduate student came into the news as it disclosed that it has found two planets orbiting stars over 1,200 light-years from Earth. At present, about 4,000 exoplanets are already known. So, the discovery of two additional might not appear like big news. However, it’s who discovered them and how that’s grabbing attention.
Anne Dattilo, who is a senior at the University of Texas, Austin, discovered the planets by employing an AI program to move through a huge data gathered by NASA’s Kepler space telescope. By employing AI, the 22-year-old is assisting to usher in a novel era in the astronomical study. A year and a half ago, Dattilo was connected with the project. Kepler was lifted off in 2009. It was intended to point at a tiny patch of sky and measure the light from about 100,000 stars in its field of view.
