Giant impacts refer to collisions between two objects each of which is massive enough to be considered at least a planetary embryo. The putative collision suffered by the proto-Earth that created the Moon is a prime example, though most Solar System bodies bear signatures of such collisions. Current planet formation models predict that an epoch of giant impacts may be inevitable, and observations of debris around other stars are providing mounting evidence that giant impacts feature in the… 
Debris Disks: Probing Planet Formation
Debris disks are the dust disks found around ~20% of nearby main sequence stars in far-IR surveys. They can be considered as descendants of protoplanetary disks or components of planetary systems,
Extreme Debris Disk Variability: Exploring the Diverse Outcomes of Large Asteroid Impacts During the Era of Terrestrial Planet Formation
The most dramatic phases of terrestrial planet formation are thought to be oligarchic and chaotic growth, on timescales of up to 100-200 Myr, when violent impacts occur between large planetesimals of
Carbon monoxide gas produced by a giant impact in the inner region of a young system.
Spectrally resolved detection of a carbon monoxide gas ring co-orbiting with dusty debris around HD 172555 suggests that planetary-scale collisions can release large amounts of gas as well as debris, and that this gas is observable, providing a window into the composition of young planets.
Realistic collisional water transport during terrestrial planet formation
Context. According to the latest theoretical and isotopic evidence, Earth’s water content originates mainly from today’s asteroid belt region, or at least from the same precursor material. This
From Disks to Planets: The Making of Planets and Their Early Atmospheres. An Introduction
This paper is an introduction to volume 56 of the Space Science Series of ISSI, “From disks to planets—the making of planets and their proto-atmospheres”, a key subject in our quest for the origins
Stellar clustering shapes the architecture of planetary systems
Old, co-moving stellar groups around exoplanet host stars in the astrometric data from the Gaia satellite are identified and it is demonstrated that the architecture of planetary systems exhibits a strong dependence on local stellar clustering in position-velocity phase space.
A Star-sized Impact-produced Dust Clump in the Terrestrial Zone of the HD 166191 System
We report on five years of 3–5 μm photometry measurements obtained by warm Spitzer to track the dust debris emission in the terrestrial zone of HD 166191 in combination with simultaneous optical
Transient events in bright debris discs: Collisional avalanches revisited
A collisional avalanche is set off by the breakup of a large planetesimal, releasing small unbound grains that enter a debris disc located further away from the star, triggering there a collisional
Magellan/PFS Radial Velocities of GJ 9827, a late K dwarf at 30 pc with Three Transiting Super-Earths
The Kepler mission showed us that planets with sizes between that of Earth and Neptune appear to be the most common type in our Galaxy. These "super-Earths" continue to be of great interest for
The search for disks or planetary objects around directly imaged companions: a candidate around DH Tauri B
Context. In recent decades, thousands of substellar companions have been discovered with both indirect and direct methods of detection. While the majority of the sample is populated by objects


Warm Debris Disks Produced by Giant Impacts During Terrestrial Planet Formation
In our solar system, Mars-sized protoplanets frequently collided with each other during the last stage of terrestrial planet formation called the giant impact stage. Giant impacts eject a large
Debris from terrestrial planet formation: the Moon-forming collision
We study the evolution of debris created in the giant impacts expected during the final stages of terrestrial planet formation. The starting point is the debris created in a simulation of the
Debris froms giant impacts between planetary embryos at large orbital radii
We consider the observational signatures of giant impacts between planetary embryos. While the debris released in the impact remains in a clump for only a single orbit, there is a much longer lasting
Evolution of Debris Disks
Circumstellar dust exists around several hundred main sequence stars. For the youngest stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be continuously
Dating the Moon-forming impact event with asteroidal meteorites
It is inferred that the Moon formed 4.47 billion years ago, which is in agreement with previous estimates, by modeling their temporal evolution, and fitting the results to ancient impact heating signatures in stony meteorites.
Large impacts around a solar-analog star in the era of terrestrial planet formation
The real-time detection of a debris-producing impact in the terrestrial planet zone around a 35-million-year-old solar-analog star is reported, demonstrating how the time domain can become a new dimension for the study of terrestrial planet formation.
Prospects for detection of catastrophic collisions in debris disks
We investigate the prospects for detecting dust from two-body collisions during the late stages of planet formation at 1–150 AU. We develop an analytic model to describe the formation of a dusty
Collisional Stripping and Disruption of Super-Earths
The final stage of planet formation is dominated by collisions between planetary embryos. The dynamics of this stage determine the orbital configuration and the mass and composition of planets in the
It is now understood that the accretion of terrestrial planets naturally involves giant collisions, the moon-forming impact being a well-known example. In the aftermath of such collisions, the
Insights into Planet Formation from Debris Disks: I. The Solar System as an Archetype for Planetesimal Evolution
Circumstellar disks have long been regarded as windows into planetary systems. The advent of high sensitivity, high resolution imaging in the submillimeter where both the solid and gas components of
