DOI: 10.1016/j.pepi.2017.11.001
Abstract: Abstract We conduct a series of numerical experiments of thermal convection of highly compressible fluids in a two-dimensional rectangular box, in order to study the mantle convection on super-Earths. The thermal conductivity and viscosity are… read more here.

DOI: 10.1038/s41550-024-02347-z
Abstract: Water is an important component of exoplanets, with its distribution, that is, whether at the surface or deep inside, fundamentally influencing the planetary properties. The distribution of water in most exoplanets is determined by yet-unknown… read more here.

DOI: 10.1093/mnras/staa2112
Abstract: Some systems of close-in "super-Earths" contain five or more planets on non-resonant but compact and nearly coplanar orbits. The Kepler-11 system is an iconic representative of this class of system. It is challenging to explain… read more here.

DOI: 10.1093/mnras/staa3415
Abstract: We show that in extremely irradiated atmospheres of hot super-Earths shortwave absorption of CN can cause strong temperature inversions. We base this study on previous observations of 55 Cancri e, which lead us to believe… read more here.

DOI: 10.1093/mnras/stae501
Abstract: We report the conditional occurrences between three planetary types: super-Earths (m sin i < 10 M⊕, P < 100 d), warm Jupiters (m sin i > 95 M⊕, 10 < P < 100 d), and cold Jupiters (m… read more here.

DOI: 10.1093/mnras/staf1814
Abstract: Exoplanet observations show that close-in super-Earths are more common around M-dwarfs than around solar mass stars. Since the snow line in a protoplanetary disc plays a crucial role in determining the amount of solid material… read more here.

DOI: 10.1093/mnras/staf707
Abstract: Kepler and TESS observations led to the discovery of many close-in super Earths, including some with ultra-short orbital periods (≲ 1 day). During and shortly after their multi-Myr formation epoch, their GKM host stars generally have… read more here.
