Some recently discovered short-period Earth to Neptune sized exoplanets (super Earths) have low observed mean densities which can only be explained by voluminous gaseous atmospheres. Here, we study the conditions allowing the accretion and retention of such atmospheres. We self-consistently couple the nebular gas accretion onto rocky cores and the subsequent evolution of gas envelopes following the dispersal of the protoplanetary disk. Specifically, we address mass-loss due to both photo… Expand

Short-period Earth to Neptune size exoplanets (super-Earths) with voluminous gas envelopes seem to be very common. These gas atmospheres are thought to have originated from the protoplanetary disk inExpand

Combined mass and radius observations have recently revealed many short-period planets a few times the size of Earth but with significantly lower densities. A natural explanation for the low densityExpand
To cool is to keep: residual H/He atmospheres of super-Earths and sub-Neptunes
• Physics
• 2021
Super-Earths and sub-Neptunes are commonly thought to have accreted hydrogen/helium envelopes, consisting of a few to ten percent of their total mass, from the primordial gas disk. Subsequently,Expand
Inner Super-Earths, Outer Gas Giants: How Pebble Isolation and Migration Feedback Keep Jupiters Cold
• Physics

The majority of gas giants (planets of masses ≳10^2 M⊕) are found to reside at distances beyond ~1 au from their host stars. Within 1 au, the planetary population is dominated by super-Earths of 2–20Expand
The Formation of Super-Earths by Tidally Forced Turbulence
The Kepler observations indicate that many exoplanets are super-Earths, which brings about a puzzle for the core-accretion scenario. Since observed super-Earths are in the range of critical mass,Expand

Direct and statistical observational evidences suggest that photoevaporation is important in eroding the atmosphere of sub-Neptune planets. We construct full hydrodynamic simulations, coupled withExpand
Survival of Primordial Planetary Atmospheres: Photodissociation-driven Mass Loss
• Physics

The most widely-studied mechanism of mass loss from extrasolar planets is photoevaporation via XUV ionization, primarily in the context of highly irradiated planets. However, the lower energy regimeExpand
How planets grow by pebble accretion
• Physics
• 2019
Proto-planets embedded in their natal disks acquire hot envelopes as they grow and accrete solids. This ensures that the material they accrete - pebbles, as well as (small) planetesimals - willExpand
Formation of Super-Earths
Super-Earths are the most abundant planets known to date and are characterized by having sizes between that of Earth and Neptune, typical orbital periods of less than 100 days and gaseous envelopesExpand
Optically thin core accretion: how planets get their gas in nearly gas-free discs
• Physics
• 2017
Models of core accretion assume that in the radiative zones of accreting gas envelopes, radiation diffuses. But super-Earths/sub-Neptunes (1--4$R_\oplus$, 2--20$M_\oplus$) point to formationExpand
