I note from the article. "In our lifetime, we will not see the planet fall into its star," he said. "But give it another 10 million years, and this planet might not be there."
Hot Jupiters are very interesting along with many other exoplanets reported now. An exoplanet with 0.5 Jupiter mass, host star with 0.5 solar mass, and a=0.10 au and e=0, completes an orbit in 16.33 days so this report shows a much closer hot jupiter and very short orbital period. Using my example, a hot jupiter with 16 day period or so completes more than 22 billion revolutions around the host star in a one billion year time span. Other examples show hundreds of billions of revolutions, e.g.
https://phys.org/news/2021-11-exoplanets-orbiting-sun-like-star.html, more than 228 billion revolutions around the host star in one billion years for the super-hot mercury reported, HD 137496 b.
There is plenty taking place now in exoplanet reports, not only exoplanets like this article where the exoplanet may disappear in 10 million years, but also others indicating hundreds of billions of revolutions taking place around their host stars. Something to ponder concerning their ages reported
