'We can't tell yet if that water is part of the planet's atmosphere, meaning the planet has an atmosphere, or if we’re just seeing a water signature coming from the star.'
in just 1.5 Earth days, indicating that it is in the habitable zone. Furthermore, this rocky world is roughly 30 per bigger than Earth and has stronger gravity than our planet.
That’s why the team suspects water vapor may exist on its host star, particularly in cool starspots. In fact, our Sun sometimes contains water vapor in cooler sunspots than the hotter surface. And, GJ 486 b's star is noted to be much cooler than the Sun, implying the possibility of more water vapor within its starspots.“We didn't observe evidence of the planet crossing any starspots during the transits. But that doesn't mean that there aren't spots elsewhere on the star.
The team also used computer models to determine the signal, concluding that water vapor was the most likely source. The computer models, on the other hand, suggested that the signal could be coming from the planetary atmosphere or starspots.

Webb finds water vapor, but is it from a rocky planet or its star?GJ 486 b is about 30% larger than the Earth and three times as massive, which means it is a rocky world with stronger gravity than Earth. It orbits a red dwarf star in just under 1.5 Earth days. It is too close to its star to be within the habitable zone, with a surface temperature of about 800 degrees Fahrenheit. And yet, Webb observations show hints of water vapor.
