Terrestrial planets with large water inventories are likely ubiquitous and will be among the first Earth-sized planets to be characterized with upcoming telescopes. It has previously been argued that waterworlds—particularly those possessing more than 1% H2O—experience limited melt production and outgassing due to the immense pressure overburden of their overlying oceans, unless subject to high internal heating. But an additional, underappreciated obstacle to outgassing on waterworlds is the… Expand


Water Cycling between Ocean and Mantle: Super-Earths Need Not Be Waterworlds
Large terrestrial planets are expected to have muted topography and deep oceans, implying that most super-Earths should be entirely covered in water, so-called waterworlds. This is important becauseExpand
Volcanism and outgassing of stagnant-lid planets: Implications for the habitable zone
Abstract Rocky exoplanets are typically classified as potentially habitable planets, if liquid water exists at the surface. The latter depends on several factors like the abundance of water but alsoExpand
A theoretical framework for volcanic degassing chemistry in a comparative planetology perspective and implications for planetary atmospheres
Abstract Magmatic degassing is ubiquitous and enduring, yet its impact on both planetary surficial chemistry and how it may have varied among planetary systems remains imprecise. A large number ofExpand
Water Partitioning in Planetary Embryos and Protoplanets with Magma Oceans
The water content of magma oceans is widely accepted as a key factor that determines whether a terrestrial planet is habitable. Water ocean mass is determined as a result not only of water deliveryExpand
Habitability of Exoplanet Waterworlds.
We model the evolution of ocean temperature and chemistry for rocky exoplanets with 10-1000$\times$ Earth's H$_2$O but without H$_2$, taking into account C partitioning, high-pressure ice phases, andExpand
Extreme water loss and abiotic O2 buildup on planets throughout the habitable zones of M dwarfs.
In general, it is found that the initial phase of high luminosity may compromise the habitability of many terrestrial planets orbiting low-mass stars. Expand
Large H2O solubility in dense silica and its implications for the interiors of water-rich planets
Experimental evidence is reported that silica and water have significant mutual solubility at high pressure and high temperature, forming new phases containing substantial amounts of both H and Si in oxide forms, suggesting that the boundary between rock and ice layers may be “fuzzy” at the deep interiors of water-rich planets.

Water-rich planets: How habitable is a water layer deeper than on Earth?
Water is necessary for the origin and survival of life as we know it. In the search for life-friendly worlds, water-rich planets therefore are obvious candidates and have attracted increasingExpand
Heat transport in the high-pressure ice mantle of large icy moons
Abstract While the existence of a buried ocean sandwiched between surface ice and high-pressure (HP) polymorphs of ice emerges as the most plausible structure for the hundreds-of-kilometers thickExpand
Forecasting Rates of Volcanic Activity on Terrestrial Exoplanets and Implications for Cryovolcanic Activity on Extrasolar Ocean Worlds
Like the planets and moons in our solar system, the surfaces of terrestrial exoplanets may be shaped by volcanic activity. The magnitudes and rates of volcanic activity on terrestrial exoplanets willExpand
