Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
Mechanical Properties of Minerals in Lunar and HED Meteorites from Nanoindentation Testing: Implications for Space Mining
Eloy Peña-Asensio, Josep M. Trigo. Rodríguez, Jordi Sort +2
This study analyzes the mechanical and elemental properties of lunar meteorites DHOFAR 1084, JAH 838, NWA 11444, and HED meteorite NWA 6013. Utilizing microscale rock mechanics exp…
A large topographic feature on the surface of the trans-Neptunian object (307261) 2002 MS measured from stellar occultations
F. L. Rommel, F. Braga-Ribas, J. L. Ortiz +201
This work aims at constraining the size, shape, and geometric albedo of the dwarf planet candidate 2002 MS4 through the analysis of nine stellar occultation events. Using multichor…
ALMA Observations of the DART Impact: Characterizing the Ejecta at Sub-Millimeter Wavelengths
Nathan X. Roth, Stefanie N. Milam, Anthony J. Remijan +12
We report observations of the Didymos-Dimorphos binary asteroid system using the Atacama Large Millimeter/Submillimeter Array (ALMA) and the Atacama Compact Array (ACA) in support…
The multichord stellar occultation by the centaur Bienor on January 11, 2019
E. Fernández-Valenzuela, N. Morales, M. Vara-Lubiano +42
Within our program of physical characterization of trans-Neptunian objects and centaurs, we predicted a stellar occultation by the centaur (54598) Bienor to occur on January 11, 20…
Orbital characterization of superbolides observed from space: dynamical association with near-Earth objects, meteoroid streams and identification of hyperbolic meteoroids
E. Peña-Asensio, J. M. Trigo-Rodríguez, A. Rimola
There is an unceasing incoming flux of extraterrestrial materials reaching the Earth's atmosphere. Some of these objects produce luminous columns when they ablate during the hypers…
Learning about comets from the study of mass distributions and fluxes of meteoroid streams
Josep M. Trigo-Rodríguez, Jürgen Blum
Meteor physics can provide new clues about the size, structure, and density of cometary disintegration products, establishing a bridge between different research fields. From meteo…
The impact and recovery of asteroid 2018 LA
Peter Jenniskens, Mohutsiwa Gabadirwe, Qing-Zhu Yin +63
The June 2, 2018, impact of asteroid 2018 LA over Botswana is only the second asteroid detected in space prior to impacting over land. Here, we report on the successful recovery of…
Accurate 3D fireball trajectory and orbit calculation using the 3D-FireTOC automatic Python code
Eloy Peña-Asensio, Josep Maria Trigo-Rodríguez, Maria Gritsevich +1
The disruption of asteroids and comets produces cm-sized meteoroids that end up impacting the Earth's atmosphere and producing bright fireballs that might have associated shock wav…
Physically based alternative to the PE criterion for meteoroids
Manuel Moreno-Ibáñez, Maria Gritsevich, Josep M. Trigo-Rodríguez +1
Meteoroids impacting the Earth atmosphere are commonly classified using the PE criterion. This criterion was introduced to support the identification of the fireball type by empiri…
Accretion of water in carbonaceous chondrites: current evidence and implications for the delivery of water to early Earth
Josep M. Trigo-Rodríguez, Albert Rimola, Safoura Tanbakouei +2
Protoplanetary disks are dust-rich structures around young stars. The crystalline and amorphous materials contained within these disks are variably thermally processed and accreted…
Analysis of the September -Perseid outburst in 2013
J. M. Madiedo, J. Zamorano, J. M. Trigo-Rodriguez +11
We analyze the outburst experienced by the September -Perseid meteor shower on 9 September 2013. As a result of our monitoring the atmospheric trajectory of 60 multi-s…
Detection and Characterization of Micrometeoroids with LISA Pathfinder
James Ira Thorpe, Cameron Parvini, Josep Trigo-Rodriguez
The Solar System contains a population of dust and small particles originating from asteroids, comets, and other bodies. These particles have been studied using a number of techniq…
Orbit and dynamic origin of the recently recovered Annama's H5 chondrite
Josep M. Trigo-Rodriguez, Esko Lyytinen, Maria Gritsevich +7
We describe the fall of Annama meteorite occurred in the remote Kola Peninsula (Russia) close to Finnish border on April 19, 2014 (local time). The fireball was instrumentally obse…
Bright Fireballs Associated with the Potentially Hazardous Asteroid 2007LQ19
Jose M. Madiedo, Josep M. Trigo-Rodriguez, Jose L. Ortiz +2
We analyze here two very bright fireballs produced by the ablation in the atmosphere of two large meteoroids in 2009 and 2010. These slow-moving and deep-penetrating events were ob…
Comets formed in solar-nebula instabilities! -- An experimental and modeling attempt to relate the activity of comets to their formation process (corrigendum included)
Jürgen Blum, Bastian Gundlach, Steffen Mühle +1
When comet nuclei approach the Sun, the increasing energy flux through the surface layers leads to sublimation of the underlying ices and subsequent outgassing that promotes the ob…
