Meteor observations as a tool to constrain cosmogonic models of the Solar System

V. I. Kuksenko, Juraj Tóth

Recent observations of small bodies of the Solar System showed evidence of the presence of refractory (asteroidal) material in the Oort cloud. Different models of the origin of the Solar System predict different numbers of rocky objects in the Oort cloud, meaning …

Comparing the data-reduction pipelines of FRIPON, DFN, WMPL, and AMOS: Case study of the Geminids

Patrick Shober, Jérémie Vaubaillon, Simon Anghel, Hadrien A. R. Devillepoix et autres

Context . The number of meteor observation networks has expanded rapidly due to declining hardware costs, enabling professional and amateur groups to contribute substantial datasets. An accurate data reduction remains challenging, however, because variations in processing methods can significantly affect the trajectory …

Comparing the data reduction pipelines of FRIPON, DFN, WMPL, and AMOS: Geminids Case Study

Patrick Shober, J. Vaubaillon, Simon Anghel, Hadrien A. R. Devillepoix et autres

Methods. We processed a dataset of 584 Geminid fireballs observed by FRIPON between 2016 and 2023. The single-station astrometric data is converted into the Global Fireball Exchange (GFE) standard format for uniform processing. We assess variations in trajectory, velocity, radiant, and orbital …

Characterization of achondritic meteoroid impactors: spectra, dynamics and ablation properties

Pavol Matlovič, Adriana Pisarčíková, Veronika Pazderová, Hadrien A. R. Devillepoix et autres

Observing meteors through a combination of spectral and multi-station trajectory measurements presents unique opportunities for mapping the compositional diversity of small Solar System bodies from various orbital sources. This research is conducted by the AMOS (All-sky Meteor Orbit System) network, providing global …

A very young τ-Herculid meteor cluster observed during a 2022 shower outburst

Pavel Koten, D. Čapek, Juraj Tóth, L. Shrbený et autres

Context. To date, only a few meteor clusters have been instrumentally recorded. This means that every new detection is an important contribution to the understanding of these phenomena, which are thought to be evidence of the meteoroid fragmentation in the Solar System. …

Spectral properties of ablating meteorite samples for improved meteoroid composition diagnostics

Pavol Matlovič, Adriana Pisarčíková, Veronika Pazderová, Stefan Loehle et autres

Emission spectra and diagnostic spectral features of a diverse range of ablated meteorite samples with a known composition are presented. We aim to provide a reference spectral dataset to improve our abilities to classify meteoroid composition types from meteor spectra observations. The …

Visual observation of meteorite ablation in plasma wind tunnel experiments

Felix Grigat, Stefan Loehle, Jérémie Vaubaillon, Pavol Matlovič et autres

A set of 28 different meteorites was tested in 32 ablation experiments in the plasma wind tunnel PWK1 at the Institute of Space Systems. All meteorites were exposed to the same flow condition in consecutive experiments. This paper presents the detailed analysis …
