In spite of substantial advancements in simulating planet formation, the planet Mercury’s diminutive mass and isolated orbit and the absence of planets with shorter orbital periods in the solar system continue to befuddle numerical accretion models. Recent studies have shown that if massive embryos (or even giant planet cores) formed early in the innermost parts of the Sun’s gaseous disk, they would have migrated outward. This migration may have reshaped the surface density profile of…

Dark spots on Mercury show no signs of weathering during 30 Earth months

Dark spots on Mercury are recently-formed thin and low-reflectance materials that are related with volatile activity and supposed to be much shorter-lived than their central hollows. Containing

Dynamical Avenues for Mercury’s Origin. I. The Lone Survivor of a Primordial Generation of Short-period Protoplanets

The absence of planets interior to Mercury continues to puzzle terrestrial-planet formation models, particularly when contrasted with the relatively high derived occurrence rates of short-period

Dynamical Avenues for Mercury’s Origin. II. In Situ Formation in the Inner Terrestrial Disk

Modern terrestrial-planet formation models are highly successful at consistently generating planets with masses and orbits analogous to those of Earth and Venus. In stark contrast to classic

Planet heating prevents inward migration of planetary cores

It is reported that asymmetries in the temperature rise associated with accreting infalling material produce a force (which gives rise to an effect that is called ‘heating torque’) that counteracts inward migration and provides a channel for the formation of giant planets.

Terrestrial Planet Formation: Constraining the Formation of Mercury

How the four terrestrial planets of the solar system formed is one of the most fundamental questions in the planetary sciences. Particularly, the formation of Mercury remains poorly understood. We

Formation of planetary systems by pebble accretion and migration

At least 30% of main sequence stars host planets with sizes of between 1 and 4 Earth radii and orbital periods of less than 100 days. We use N-body simulations including a model for gas-assisted

Formation of the terrestrial planets in the solar system around 1 au via radial concentration of planetesimals

No planets exist inside the orbit of Mercury and the terrestrial planets of the solar system exhibit a localized configuration. According to thermal structure calculation of protoplanetary disks, a

Mars’ growth stunted by an early giant planet instability

Growing the terrestrial planets from the gradual accumulation of submeter-sized objects

It is shown that a new mode of planet formation known as “Viscous Stirred Pebble Accretion,” which has recently been shown to produce the giant planets, also naturally explains the small size of Mars and the low mass of the asteroid belt, and there is a unified model that can be used to explain all of the basic properties of the authors' solar system.

The structure of protoplanetary discs around evolving young stars

The formation of planets with gaseous envelopes takes place in protoplanetary accretion discs on time scales of several million years. Small dust particles stick to each other to form pebbles,
