Abstract:
The Kepler telescope mission has revealed that Super-Earths (<1.5Rearth) and Sub-Neptunes (2-3Rearth) are the most common types of exoplanets. Additionally, planetary formation and evolution models suggest that the former category comprises bare rocky planets, while the latter includes planets with hydrogen-rich atmospheres and rocky cores. If a planet in the former category is close-in, and one from the latter category possesses a massive hydrogen atmosphere, these planets should exhibit a magma ocean surface. I will discuss/talk about previous and our group’s ongoing theoretical studies on the possible atmosphere of super-Earth/sub-Neptune with magma ocean.
