In this study, we treat Earth as an exoplanet and investigate our home planet by means of a potential future mid-infrared (MIR) space mission called the Large Interferometer For Exoplanets […]
Exploring exoplanets has transformed our understanding of the universe by revealing many planetary systems that defy our current understanding.
Outgassing is a central process during the formation and evolution of terrestrial planets and their atmospheres both within and beyond the solar system.
Webb measured the dayside temperature of rocky exoplanet TRAPPIST-1 b and found it to be about 450 degrees F (227 degrees C), suggesting it has no significant atmosphere.
The James Webb Space Telescope (JWST) is now observing Y dwarfs, the coldest known brown dwarfs, with effective temperatures T_eff <= 475 K.
The atmosphere of a terrestrial planet that is replenished with secondary gases should have accumulated hydrogen-rich gas from its protoplanetary disk.
A new study shows unprecedented heat is likely to lead to the next mass extinction since the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.
The evolution of a planet’s atmosphere depends strongly on its host star’s properties. When their host stars are younger, planets can experience stronger winds and EUV emissions. This is particularly […]
Recent work on the characterization of small exoplanets has allowed us to accumulate growing evidence that the sub-Neptunes with radii greater than ∼2.5R⊕ often host H2/He-dominated atmospheres both from measurements […]
The Ariel Space Mission aims to observe a diverse sample of exoplanet atmospheres across a wide wavelength range of 0.5 to 7.8 microns. The observations are organized into four Tiers, […]
