Aging Stars May Be Destroying Their Closest Planets

Astronomers discover dying stars eating their planets

Astronomers have discovered that aging stars may be devouring their closest giant planets as they swell into red giants. Using NASA’s TESS telescope to study nearly half a million stars, scientists found far fewer close-orbiting planets around older, expanded stars—clear evidence that many have already been destroyed.

Aging stars may be destroying their closest planets

Aging stars may be destroying the giant planets orbiting closest to them, according to a new study by astronomers at UCL and the University of Warwick.

Astronomers Reveal Aging Stars Could Be Devouring Nearby Giant Exoplanets

During the concluding phase of their main sequence life, stars with mass comparable to the Sun experience a transformative evolution. This evolutionary process is likely to affect the surrounding planetary systems. As the star expands in its post-main-sequence stage, astronomers anticipate that most exoplanets detected to date may be engulfed by the growing star. An [...] The post Astronomers Reveal Aging Stars Could Be Devouring Nearby Giant Ex…

At the end of their main-sequence life span, stars similar in mass to our Sun will undergo a period of evolution. The post Aging Stars May Be Destroying Close-In Giant Exoplanets, Astronomers Say appeared first on Sci.News: Breaking Science News.

Ageing Stars May Be Destroying Their Closest Planets - Astrobiology

Ageing stars may be destroying the giant planets orbiting closest to them, new research shows – offering a glimpse into the possible fate of the likes of Jupiter and Saturn in our own solar system. Once stars like the Sun run out of hydrogen fuel, they cool down and expand to become red giants. In […] The post Ageing Stars May Be Destroying Their Closest Planets appeared first on Astrobiology.
