HD 163296 and its Giant Planets: Creation of Exo-comets, Interstellar Objects and Transport of Volatile Material
D. Polychroni, D. Turrini, S. Ivanovski +14
The birth of giant planets in protoplanetary disks is known to alter the structure and evolution of the disk environment, but most of our knowledge focuses on its effects on the ob…
Macro-scale roughness reveals the complex history of asteroids Didymos and Dimorphos
Jean-Baptiste Vincent, Erik Asphaug, Olivier Barnouin +22
Morphological mapping is a fundamental step in studying the processes that shaped an asteroid surface. Yet, it is challenging and often requires multiple independent assessments by…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
Theodore Kareta, Cristina Thomas, Jian-Yang Li +85
The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…
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…
The Reflectance Spectra of CV-CK Carbonaceous chondrites from the Near Infrared to the Visible
Safoura Tanbakouei, Josep M. Trigo-Rodriguez, J. Llorca +3
Carbonaceous chondrite meteorites are so far the only available samples representing carbon-rich asteroids and in order to allow future comparison with samples returned by missions…
Comparing the reflectivity of ungrouped carbonaceous chondrites with that of short period comets like 2P/Encke
Safoura Tanbakouei, Josep M. Trigo-Rodriguez, Jurgen blum +2
Aims. The existence of asteroid complexes produced by the disruption of these comets suggests that evolved comets could also produce high-strength materials able to survive as mete…
Annama H chondrite - mineralogy, physical properties, cosmic ray exposure, and parent body history
Tomáš Kohout, Jakub Haloda, Patricie Halodová +27
The fall of the Annama meteorite occurred early morning (local time) on April 19, 2014 on the Kola Peninsula (Russia). Based on mineralogy and physical properties, Annama is a typi…
UV to far-IR reflectance spectra of carbonaceous chondrites. I. Implications for remote characterization of dark primitive asteroids targeted by sample-return missions
Josep M. Trigo-Rodriguez, Carles E. Moyano-Cambero, Jordi Llorca +8
We analyze here a wide sample of carbonaceous chondrites from historic falls (e.g. Allende, Cold Bokkeveld, Kainsaz, Leoville, Murchison, Murray and Orgueil), and from NASA Antarct…
The effect of aqueous alteration and metamorphism in the survival of presolar silicate grains in chondrites
Josep M. Trigo-Rodriguez, Jurgen Blum
Relatively small amounts (typically between 2-200 parts per million) of presolar grains have been preserved in the matrices of chondritic meteorites. The measured abundances of the…
The Role of Massive Agb Stars in the Early Solar System Composition
Josep M. Trigo-Rodriguez, Domingo Anibal Garcia-Hernandez, Maria Lugaro +4
We demonstrate that a massive asymptotic giant branch (AGB) star is a good candidate as the main source of short-lived radionuclides in the early solar system. Recent identificatio…
Rubidium-Rich Asymptotic Giant Branch Stars
D. A. Garcia-Hernandez, P. Garcia-Lario, B. Plez +3
A long debated issue concerning the nucleosynthesis of neutron-rich elements in Asymptotic Giant Branch (AGB) stars is the identification of the neutron source. We report intermedi…
