The Distribution of Earth-Impacting Interstellar Objects
Darryl Z. Seligman, Dušan Marčeta, Eloy Peña-Asensio
In this paper we calculate the expected orbital elements, radiants, and velocities of Earth-impacting interstellar objects. We generate a synthetic population of inte…
The interstellar flux gap: From dust to kilometer-scale objects
Eloy Peña-Asensio, Darryl Z. Seligman
Context. Three kilometer-sized interstellar objects (ISOs) have been detected transiting the Solar System, and spacecraft have directly measured micrometer-scale interstellar dust…
Century-Scale Effect of Climate Change on Meteorite Falls
Eloy Peña-Asensio, Denis Vida, Ingrid Cnossen +1
Climate change is inducing a global atmospheric contraction above the tropopause (~10 km), leading to systematic decrease in neutral air density. The impact of climate change on sm…
Error dependencies in the space-based CNEOS fireball database
Eloy Peña-Asensio, Hector Socas-Navarro, Darryl Z. Seligman
We evaluate the reliability of CNEOS-derived ephemerides of fireball events given the absence of the underlying data. We analyzed 18 events that have both (i) sufficient satellite…
On the spatiotemporal coincidence of meteorites in recent fall search campaigns
P. Grèbol-Tomàs, E. Peña-Asensio, J. M. Trigo-Rodríguez +1
The meteoritical community widely assumes that the probability of finding two meteorites from different falls laying in close proximity is negligible. However, recent studies have…
Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS
Darryl Z. Seligman, Marco Micheli, Davide Farnocchia +44
We report initial observations aimed at the characterization of a third interstellar object. This object, 3I/ATLAS or C/2025 N1 (ATLAS), was discovered on 2025 July 1 UT and has an…
Meteoroid stream identification with HDBSCAN unsupervised clustering algorithm
Eloy Peña-Asensio, Fabio Ferrari
Accurate identification of meteoroid streams is central to understanding their origins and evolution. However, overlapping clusters and background noise hinder classification, an i…
The Feasibility of a Spacecraft Flyby with the Third Interstellar Object 3I/ATLAS from Earth or Mars
Atsuhiro Yaginuma, Tessa Frincke, Darryl Z. Seligman +5
We investigate the feasibility of a spacecraft mission to conduct a flyby of 3I/ATLAS, the third macroscopic interstellar object discovered on July 1 2025, as it traverses the Sola…
Inferring Fireball Velocity Profiles and Characteristic Parameters of Meteoroids from Incomplete Datasets
Eloy Peña-Asensio, Maria Gritsevich
Extracting additional information from old or incomplete fireball datasets remains a challenge. To address missing point-by-point observations, we introduce a method for estimating…
Multi-parameter constraints on empirical infrasound period-yield relations for bolides and implications for planetary defense
Elizabeth A. Silber, Josep M. Trigo-Rodríguez, Iyare Oseghae +18
How effective are methods for estimating bolide energies from infrasound signal period-yield relationships? A single global period-energy relation can obscure significant variabili…
