Will the sun 'devour' the Earth?
The international team of astronomers has found the first evidence of the star's "eating" of its own planets. This can happen similarly to Earth, when the Sun becomes older and dies in the next 5 billion years.

International astronomers said they found the giant planet named BD + 48 740 in the elliptical orbit of the "giant aging" star . This star is much older than the Sun with a radius of seven times the solar radius.
Using the Hobby-Eberly telescope to study old stars and searching for planets around it, scientists found the star's chemical composition to be unusual.
When analyzing the spectrum, experts say its chemical composition contains unusually high amounts of lithium. Lithium is a component created primarily from the Big Bang explosion 14 billion years ago and is easily destroyed in the star's heart.
When the mutant amount of lithium in the star said, scientists know that this is unusual. Scientists believe that this amount of lithium generated from the planet is 'twisted' into the star. The amount of lithium gets higher when this old star starts to "digest" that "unlucky" planet.
The second thing worth noting in the proof is that the elliptical orbit of this giant planet is distorted. Its tightening point is only wider than the narrowest point of Mars orbit, but at the farthest point it swells greatly. This may be the most eccentric trajectory ever.
Scientists believe that the star's high "pollution" of lithium due to the planet's "swallowing" process is the reason for the previous disappearances of some planets in the universe.
