9 p, 1.5 MB Deep machine learning for meteor monitoring : Advances with transfer learning and gradient-weighted class activation mapping / Peña-Asensio, Eloy (Universitat Autònoma de Barcelona. Departament de Química) ; Trigo Rodríguez, Josep Maria (Institut de Ciències de l'Espai) ; Grèbol-Tomàs, Pau (Institut de Ciències de l'Espai) ; Regordosa-Avellana, David (Spanish Meteor Network) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química)
In recent decades, the use of optical detection systems for meteor studies has increased dramatically, resulting in huge amounts of data being analyzed. Automated meteor detection tools are essential for studying the continuous meteoroid incoming flux, recovering fresh meteorites, and achieving a better understanding of our Solar System. [...]

Departament de Química)
The observation of interstellar objects 1I/'Oumuamua and 2I/Borisov suggests the existence of a larger population of smaller projectiles that impact our planet with unbound orbits. We analyze an asteroidal grazing meteor (FH1) recorded by the Finnish Fireball Network on October 23, 2022. [...]

12 p, 4.3 MB Accurate 3D fireball trajectory and orbit calculation using the 3D-FIRETOC automatic Python code / Peña-Asensio, Eloy (Institut de Ciències de l'Espai) ; Trigo Rodríguez, Josep Maria (Institut de Ciències de l'Espai) ; Gritsevich, Maria (Finnish Geospatial Research Institute) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química)
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 waves or, in geometrically favourable occasions excavate craters that put them into unexpected hazardous scenarios. [...]
