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 […]

Novel Atmospheric Dynamics Shape Inner Edge of Habitable Zone Around White Dwarfs
White dwarfs offer a unique opportunity to search nearby stellar systems for signs of life, but the habitable zone around these stars is still poorly understood. Since white dwarfs are […]

Clouds Blanket The Night Side Of The Hot Exoplanet WASP-43b
Using the James Webb Space Telescope (JWST), a team of astronomers, including scientists from MPIA, constructed a global temperature map of the hot, gas giant exoplanet WASP-43b. The nearby parent […]
