"Led by researchers from the Trottier Institute for Research on Exoplanets at 看片视频 University and the Universit茅 de Montr茅al (UdeM), a team of astronomers harnessed the power of the revolutionary Webb Telescope to study HAT-P-18 b. Their聽findings, detailed in the journal聽Monthly Notices of the Royal Astronomical聽Society (MNRAS), provide a comprehensive portrait of the hot Saturn鈥檚 atmosphere while delving into the complexities of distinguishing atmospheric signals from stellar activity.
鈥淭he James Webb Space Telescope provides exoplanet observations so precise that we are limited by our understanding of their host stars. Fortunately, those same data- especially with the made-in-Canada NIRISS instrument- allow us to measure what the star is doing during our observations and correct for it, so we can figure out exactly what is in these planets' atmospheres,鈥� said Nicolas Cowan, Professor in 看片视频 University鈥檚 Department of Earth and Planetary Sciences"
