Small-Body Science with the Nautilus Space Observatory: From Cislunar Space Resilience to Mapping the Kuiper-Belt-to-Oort-Cloud Transition
J. de Wit, A. Y. Burdanov, P. McGill +3
A new generation of space-based observatories can transform small-body science from the local Earth-Moon environment to the Solar System's dynamical frontier, where planetary contr…
Physical Analysis of Bennu Samples Reveals Regolith Production by Collisional Disruption on Near-Earth Asteroids
R. -L. Ballouz, A. J. Ryan, R. J. Macke +25
Owing to the extremely low gravity of small near-Earth asteroids (NEAs), it has been assumed that impact-generated rock fragments escape into space and thus do not contribute to th…
Most High-density Exoplanets Are Unlikely to Be Remnant Giant-planet Cores
Zifan Lin, Saverio Cambioni, Sara Seager
Some exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories - metal-rich formation hypothesis and naked core…
Surface properties of the Kalliope-Linus system from ALMA and VLA data
Katherine de Kleer, Saverio Cambioni, Bryan Butler +1
The abundance and distribution of metal in asteroid surfaces can be constrained from thermal emission measurements at radio wavelengths, informing our understanding of planetesimal…
Can metal-rich worlds form by giant impacts?
Saverio Cambioni, Benjamin P. Weiss, Erik Asphaug +5
Planets and stars are expected to be compositionally linked because they accrete from the same material reservoir. However, astronomical observations revealed the existence of exop…
Estimate of water and hydroxyl abundance on asteroid (16) Psyche from JWST data
Stephanie G. Jarmak, Tracy M. Becker, Charles E. Woodward +10
Our understanding of Solar System evolution is closely tied to interpretations of asteroid composition, particularly the M-class asteroids. These asteroids were initially thought t…
The Heterogeneous Surface of Asteroid (16) Psyche
Saverio Cambioni, Katherine de Kleer, Michael Shepard
Main-belt asteroid (16) Psyche is the largest M-type asteroid, a class of object classically thought to be the metal cores of differentiated planetesimals and the parent bodies of…
A New Database of Giant Impacts over a Wide Range of Masses and with Material Strength: A First Analysis of Outcomes
Alexandre Emsenhuber, Erik Asphaug, Saverio Cambioni +4
In the late stage of terrestrial planet formation, planets are predicted to undergo pairwise collisions known as giant impacts. Here we present a high-resolution database of giant…
The Role of Giant Impacts in Planet Formation
Travis S. J. Gabriel, Saverio Cambioni
Planets are expected to conclude their growth through a series of giant impacts: energetic, global events that significantly alter planetary composition and evolution. Computer mod…
An improved model of metal/silicate differentiation during Earth's accretion
K. I. Dale, D. C. Rubie, M. Nakajima +5
We improved the algorithm presented in Rubie et al. (2015) to model the chemical evolution of Earth driven by iron/silicate differentiation during the planet's accretion. The press…
Successful Kinetic Impact into an Asteroid for Planetary Defense
R. Terik Daly, Carolyn M. Ernst, Olivier S. Barnouin +98
While no known asteroid poses a threat to Earth for at least the next century, the catalog of near-Earth asteroids is incomplete for objects whose impacts would produce regional de…
Ejecta from the DART-produced active asteroid Dimorphos
Jian-Yang Li, Masatoshi Hirabayashi, Tony L. Farnham +61
Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the p…
TOI-1075 b: A Dense, Massive, Ultra-Short Period Hot Super-Earth Straddling the Radius Gap
Zahra Essack, Avi Shporer, Jennifer A. Burt +29
Populating the exoplanet mass-radius diagram in order to identify the underlying relationship that governs planet composition is driving an interdisciplinary effort within the exop…
After DART: Using the first full-scale test of a kinetic impactor to inform a future planetary defense mission
Thomas S. Statler, Sabina D. Raducan, Olivier S. Barnouin +38
NASA's Double Asteroid Redirection Test (DART) is the first full-scale test of an asteroid deflection technology. Results from the hypervelocity kinetic impact and Earth-based obse…
Asteroid 16 Psyche: Shape, Features, and Global Map
Michael K. Shepard, Katherine de Kleer, Saverio Cambioni +9
We develop a shape model of asteroid 16 Psyche using observations acquired in a wide range of wavelengths: Arecibo S-band delay-Doppler imaging, Atacama Large Millimeter Array (ALM…
Collision Chains among the Terrestrial Planets. III. Formation of the Moon
Erik Asphaug, Alexandre Emsenhuber, Saverio Cambioni +2
In the canonical model of Moon formation, a Mars-sized protoplanet "Theia" collides with proto-Earth at close to their mutual escape velocity and a common impact angl…
Collision Chains among the Terrestrial Planets. II. An Asymmetry between Earth and Venus
Alexandre Emsenhuber, Erik Asphaug, Saverio Cambioni +2
During the late stage of terrestrial planet formation, hit-and-run collisions are about as common as accretionary mergers, for expected velocities and angles of giant impacts. Aver…
The Effect of Inefficient Accretion on Planetary Differentiation
Saverio Cambioni, Seth A. Jacobson, Alexandre Emsenhuber +5
Pairwise collisions between terrestrial embryos are the dominant means of accretion during the last stage of planet formation. Hence, their realistic treatment in N-body studies is…
