Astronomers have discovered that the presence of the right-sized planet orbiting its parent fast enough seems to slow the star's aging process.
The effect exoplanets have on the rotation of their host stars is a little tricky to study. If you're looking at one star and one planet, you basically have no way of knowing if the rotation speed has been influenced by the planet at all.

Astronomers used data from GAIA, the Dark Energy Survey, and the X-Shooter instrument at the European Southern Observatory to peer at this system. They identified debris from orbiting planetesimals , which are globs of dust and rock which are created during planetary formation.
One of the stars is very red, showing the presence of sodium, lithium, potassium, and perhaps, carbon. The other star is extremely blue, which is caused by its helium and hydrogen atmosphere. The debris around these stars contains metallic elements, which suggest it came from planetary bodies.

Researchers in Alaska have blasted a beam of radio signals some 374 million miles into space—all the way to Jupiter.
On Earth, this charged atmospheric region, called the ionosphere , is located roughly 50 to 400 miles above the planet's surface, and scientists already know a lot about it. The ionospheres of other planets, however, remain mostly mysterious.
Tuesday's Rare 'Blood Moon' Eclipse Will Be The Last Until 2025!
We've been treated to spectacular skywatching in 2022, with the rare alignment of five planets in June, and a total lunar eclipse back in May.
After this week, the next total lunar eclipse won't be until the 13-14 March 2025 (depending on where you're located).
Thankfully the sun is ordinary | News | grandrapidsmn.com
We here on Earth are blessed with one very special star we call the sun. It is a rather ordinary star and even considered to be on the large end of the 'dwarf' star spectrum. There are stars hundreds of times bigger and much more powerful.
Now imagine you have not one but two suns in the sky. One is yellow like our sun and one is a bit brighter. Far off there would be another sun, but so small and distant it would merely appear to be the brightest star in the sky.
