Effects of Transient Stellar Emissions On Planetary Climates Of Tidally-locked Exo-earths
Space weather events in planetary environments sourced from transient host star emissions, including stellar flares, coronal mass ejections, and stellar proton events, can substantially influence an exoplanet’s climate and atmospheric […]

Planetary Rhythms: Synchronous Circulation On Variably Irradiated Asynchronous Planets
Tidal locking of planets to their host stars results in an atmospheric circulation with a hotspot fixed to the frame of reference of the planet. On the other hand, asynchronously […]

Uranus’ Swaying Moons Will Help Spacecraft Seek Out Hidden Oceans
When NASA’s Voyager 2 flew by Uranus in 1986, it captured grainy photographs of large ice-covered moons. Now nearly 40 years later, NASA plans to send another spacecraft to Uranus, […]

The Response of Planetary Atmospheres to the Impact of Icy Comets I: Tidally-Locked exo-Earths
Impacts by rocky and icy bodies are thought to have played a key role in shaping the composition of solar system objects, including the Earth’s habitability. Hence, it is likely […]

Earth-like Exoplanets In Spin-orbit Resonances: Climate Dynamics, 3D Atmospheric Chemistry, and Observational Signatures
Terrestrial exoplanets around M- and K-type stars are important targets for atmospheric characterisation. Such planets are likely tidally locked with the order of spin-orbit resonances (SORs) depending on eccentricity. We […]

Surprising Spin-orbit Resonances of Rocky Planets
Recent works suggest that, in multiplanetary systems, a close-in exoplanet can sometimes avoid becoming tidally locked to its host star if it is captured into a secular spin-orbit resonance with […]

Astronomers Catch A Glimpse Of A Uniquely Inflated And Asymmetric Exoplanet
Astronomers from the University of Arizona, along with an international group of researchers, observed the atmosphere of a hot and uniquely inflated exoplanet using NASA’s James Webb Space Telescope. The […]

How Land-Mass Distribution Influences the Atmospheric Dynamics of Tidally Locked Terrestrial Exoplanets
Interpretation of the ongoing efforts to simulate the atmospheres of potentially-habitable terrestrial exoplanets requires that we understand the underlying dynamics and chemistry of such objects to a much greater degree […]

Asymmetries In The Simulated Ozone Distribution On TRAPPIST-1e Due To Orography
TRAPPIST-1e is a tidally locked rocky exoplanet orbiting the habitable zone of an M dwarf star. Upcoming observations are expected to reveal new rocky exoplanets and their atmospheres around M […]
