James Webb is a GO for Cycle 2 Observations! universetoday storybywill
One of the most anticipated aspects of themission is how it will assist with the transition currently taking place in exoplanet science. Whereas astronomers were largely focused on the discovery process in the past, improved instruments, methods, and analytics are shifting the focus toward characterization.
.” This study will characterize the atmospheres of giant rocky planets around M-type stars to address one of the JWST’s primary science goals: how atmospheric composition can affect a planet’s formation and evolutionary history. to observe short-period Jupiter-sized planets around red dwarfs, which pose challenges to current theories about planet formation and represent an extreme regime that is poorly understood.
“We will use NIRISS SOSS and NIRSpec G395H to measure atmospheric transmission spectra for a sample of the five most promising water-world candidates identified by their bulk densities, transmission spectroscopy metrics, and the expected depths of molecular spectral features. By surveying multiple targets, our program will provide vital constraints on the existence of water worlds and will allow us to start characterizing the chemical diversity of their atmospheres.
