Consistency between dynamical modeling and photometrically derived masses of fireballs
Eloy Peña-Asensio, Maria Gritsevich
We present a three-point inverse solution for reconstructing meteoroid deceleration and mass-loss histories from sparse observations constrained only by the entry, peak-brightness,…
The Distribution of Earth-Impacting Interstellar Objects
Darryl Z. Seligman, DuÅ¡an MarÄeta, 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…
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…
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…
