Close-in super-Earths, with radii R = 2-5 R_Earth and orbital periods P < 100 days, orbit more than half, and perhaps nearly all Sun-like stars in the universe. We use this omnipresent population to construct the minimum-mass extrasolar nebula (MMEN), the circumstellar disk of solar-composition solids and gas from which such planets formed, if they formed near their current locations and did not migrate. In a series of back-of-the-envelope calculations, we demonstrate how in-situ formation in…

FORMATION OF CLOSE IN SUPER-EARTHS AND MINI-NEPTUNES: REQUIRED DISK MASSES AND THEIR IMPLICATIONS

Recent observations by the Kepler space telescope have led to the discovery of more than 4000 exoplanet candidates consisting of many systems with Earth- to Neptune-sized objects that reside well

The formation of super-Earths and mini-Neptunes with giant impacts

The majority of discovered exoplanetary systems harbour a new class of planets, bodies that are typically several times more massive than the Earth but that orbit their host stars well inside the

No universal minimum-mass extrasolar nebula: evidence against in situ accretion of systems of hot super-Earths

It has been proposed that the observed systems of hot super-Earths formed in situ from high-mass disks. By fitting a disk profile to the entire population of Kepler planet candidates, Chiang &

THE INFLUENCE OF MAGNETIC FIELD GEOMETRY ON THE FORMATION OF CLOSE-IN EXOPLANETS

Approximately half of Sun-like stars harbor exoplanets packed within a radius of ∼0.3 au, but the formation of these planets and why they form in only half of known systems are still not well

The imprint of the protoplanetary disc in the accretion of super-Earth envelopes

Super-Earths are by far the most dominant type of exoplanet, yet their formation is still not well understood. In particular, planet formation models predict that many of them should have accreted

ON THE FORMATION OF SUPER-EARTHS WITH IMPLICATIONS FOR THE SOLAR SYSTEM

We first consider how the level of turbulence in a protoplanetary disk affects the formation locations for the observed close-in super-Earths in exosolar systems. We find that a protoplanetary disk

In Situ Formation of Super-Earth/Sub-Neptune Driven by the Planetary Rotation

Kepler’s observation shows that many of the detected planets are super-Earths. They are inside a range of critical masses overlapping the core masses (2–20 M ⊕), which would trigger the runaway

Formation of close-in super-Earths in evolving protoplanetary disks due to disk winds

Context. Planets with masses larger than about 0.1 M⊕ undergo rapid inward migration (type I migration) in a standard protoplanetary disk. Recent magnetohydrodynamical simulations revealed the

Super-Earth Atmospheres: Self-Consistent Gas Accretion and Retention

Some recently discovered short-period Earth- to Neptune-sized exoplanets (super-Earths) have low observed mean densities that can only be explained by voluminous gaseous atmospheres. Here, we study

The Formation and Dynamics of Super-Earth Planets

Super-Earths, objects slightly larger than Earth and slightly smaller than Uranus, have found a special place in exoplanetary science. As a new class of planetary bodies, these objects have

A Minimum-Mass Extrasolar Nebula

By analogy with the minimum-mass solar nebula, we construct a surface-density profile using the orbits of the 26 precise-Doppler planets found in multiple-planet systems: Σ = 2200 (a/1 AU)-β g cm-2,

The Occurrence and Mass Distribution of Close-in Super-Earths, Neptunes, and Jupiters

TLDR
The occurrence rate of close-in planets (with orbital periods less than 50 days), based on precise Doppler measurements of 166 Sun-like stars, is reported, indicating that theoretical models of planet formation predict a deficit of planets in the domain from 5 to 30 Earth masses and with orbital periods under 50 days are in fact well populated.

A super-Earth transiting a nearby low-mass star

TLDR
Observations of the transiting planet GJ’1214b are reported, finding that the planetary mass and radius are consistent with a composition of primarily water enshrouded by a hydrogen–helium envelope that is only 0.05% of the mass of the planet.

IN SITU ACCRETION OF HYDROGEN-RICH ATMOSPHERES ON SHORT-PERIOD SUPER-EARTHS: IMPLICATIONS FOR THE KEPLER-11 PLANETS

Motivated by recent discoveries of low-density super-Earths with short orbital periods, we have investigated in situ accretion of H-He atmospheres on rocky bodies embedded in dissipating warm disks,

FORMATION AND STRUCTURE OF LOW-DENSITY EXO-NEPTUNES

Kepler has found hundreds of Neptune-size (2–6 R⊕) planet candidates within 0.5 AU of their stars. The nature of the vast majority of these planets is not known because their masses have not been

Formation and structure of the three Neptune-mass planets system around HD 69830

Since the discovery of the first giant planet outside the solar system in 1995 (Mayor & Queloz 1995, Nature, 378, 355), more than 180 extrasolar planets have been discovered. With improving detection

TERRESTRIAL PLANET FORMATION. I. THE TRANSITION FROM OLIGARCHIC GROWTH TO CHAOTIC GROWTH

We use a hybrid, multiannulus, n-body-coagulation code to investigate the growth of kilometer-sized planetesimals at 0.4-2 AU around a solar-type star. After a short runaway growth phase,

A ground-based transmission spectrum of the super-Earth exoplanet GJ 1214b

TLDR
A ground-based measurement of the transmission spectrum of GJ 1214b between wavelengths of 780 and 1,000 nm is reported, finding the lack of features in this spectrum rules out cloud-free atmospheres composed primarily of hydrogen.

MIGRATION THEN ASSEMBLY: FORMATION OF NEPTUNE-MASS PLANETS INSIDE 1 AU

We demonstrate that the observed distribution of “hot Neptune”/“super-Earth” systems is well reproduced by a model in which planet assembly occurs in situ, with no significant migration

Formation of Protoplanets from Planetesimals in the Solar Nebula

Planetary accretion from planetesimals to protoplanets is investigated using three-dimensional N-body simulations. The effect of gas drag due to solar nebula is included and realistic-sized
