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,…
Long-term outburst activity of comet 17P/Holmes and constraints on ejecta size distributions
Maria Gritsevich, Marcin Wesołowski, Josep M. Trigo-Rodríguez +4
A quantitative understanding of cometary outbursts requires robust constraints on the size distribution of ejected particles, which governs outburst dynamics and underpins estimate…
The First Instrumentally Documented Fall of an Iron Meteorite: atmospheric trajectory and ground impact
Jarmo Moilanen, Maria Gritsevich, Jaakko Visuri
Iron meteorite falls are rare compared to stony meteorites, and until recently no iron meteorite had a reliably determined pre-atmospheric orbit. This changed on 2020 November 7, w…
Spectrophotometric evidence for a metal-bearing, carbonaceous, and pristine interstellar comet 3I/ATLAS
Josep M. Trigo-Rodríguez, Maria Gritsevich, Jürgen Blum
3I/ATLAS is only the second confirmed cometary object known to enter the Solar System from interstellar space. Cosmogonic considerations suggest that this body may possess relative…
Assessing the metal and rare earth element mining potential of undifferentiated asteroids through the study of carbonaceous chondrites
Josep M. Trigo-Rodríguez, Pau Grèbol-Tomàs, Jordi Ibáñez-Insa +2
Undifferentiated asteroids, particularly the parent bodies of carbon-rich chondrite groups, might be promising candidates for future space resource utilization due to their primiti…
Lunar exosphere dynamics at the north pole following Perseid 2009 meteoroid impacts
Alexey A. Berezhnoy, Maria Gritsevich, Ekaterina A. Feoktistova +3
Observations of the lunar exosphere provide valuable insights into dynamic processes affecting the Moon, such as meteoroid bombardment. The Chamberlain model was employed to estima…
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…
Cometary Observations in Light-Polluted Environments: A case study of Interstellar Comet 2I/Borisov
Josep M. Trigo-Rodríguez, Damya Souami, Maria Gritsevich +2
Comets and asteroids have long captured human curiosity, and until recently, all documented examples belonged to our Solar System. That changed with the discovery of the first know…
Mass of particles released by comet 12P/Pons-Brooks during 2023-2024 outbursts
Maria Gritsevich, Marcin Wesołowski, Alberto J. Castro-Tirado
During its most recent return, comet 12P/Pons-Brooks experienced 14 well-documented outbursts, observed between June 13, 2023, and April 2024, at heliocentric distances ranging fro…
Feasibility of meteor surveying from a Venus orbiter
Apostolos A. Christou, Maria Gritsevich
Meteor and bolide phenomena caused by the atmospheric ablation of incoming meteoroids are predicted to occur at the planet Venus. Their systematic observation would allow to measur…
The Fireball of November 24, 1970, as the Most Probable Source of the Ischgl Meteorite
Maria Gritsevich, Jarmo Moilanen, Jaakko Visuri +13
In June 1976, a pristine meteorite stone weighing approximately 1 kg, fully covered with a fresh black fusion crust, was collected on a mountain road in the high-altitude Alpine en…
Oort cloud perturbations as a source of hyperbolic Earth impactors
Eloy Peña-Asensio, Jaakko Visuri, Josep M. Trigo-Rodríguez +4
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.…
