Three-dimensional transport-induced chemistry on temperate sub-Neptune K2-18b, Part II: the combined effects of atmospheric dynamics and chemical reactions
Jiachen Liu, Duncan Christie, Jun Yang +1
The upper atmospheres of temperate sub-Neptunes are strongly influenced by atmospheric dynamics due to their cool equilibrium temperature and thereby longer chemical timescales tha…
Three-Dimensional Ocean Dynamics and Detectability of Tidally Locked Lava Worlds
Yanhong Lai, Wanying Kang, Jun Yang +1
Tidally locked lava planets are hot, rocky worlds on close-in orbits with a permanent molten dayside. With JWST, their surfaces and atmospheres are beginning to be revealed. This w…
Ocean Circulation on Tide-locked Lava Worlds: 3D Modeling with a Simple Boundary Iteration Method
Jun Yang, Chengyao Tang, Zimu Wang +2
Tide-locked lava worlds are surface-melted rocky planets under 1:1 tidally locked orbit (i.e., synchronously rotating) with orbital period being equal to rotation period and with p…
Ocean Tides on Asynchronously Rotating Planets Orbiting Low-mass Stars
Jiaru Shi, Jun Yang, Dorian S. Abbot +3
Planets in the liquid-water habitable zone of low-mass stars experience large tidal forces, to times those on Earth, due to the small distance between the habitable z…
Formation of Near-surface Atmospheric Inversion and Surface Inversion in Hothouse Climates
Jiachen Liu, Feng Ding, Jun Yang
A hothouse climate may develop throughout Earth's history and its warming future and on potentially habitable exoplanets near the inner edge of the habitable zone. Previous studies…
Ocean Circulation on Tide-locked Lava Worlds, Part I: An Idealized 2D Numerical Model
Yanhong Lai, Jun Yang, Wanying Kang
A magma ocean is expected to exist on the dayside of tide-locked planets if surface temperature exceeds the melting temperature of typical crust. As highly prioritized targets for…
