title: Jupiter-family comets and ''JFC-like'' Meteoroids

description: Overview: 

The data shared here is examined in the study by Shober et al. "Comparing the Dynamics of Jupiter-Family Comets andComet-like Fireballs".

The study employs data from a comprehensive array of fireball networks, including the Desert Fireball Network (DFN), the European Fireball Network (EFN), the Fireball Recovery and InterPlanetary Observation Network (FRIPON), and the Meteorite Observation and Recovery Project (MORP), in conjunction with ephemeris data for 661 JFCs obtained from the NASA HORIZONS database. The fireball data analyzed and shared here are all the fireballs from the previously mentioned networks that originate from 2<Tj<3 orbits, which are nominally ''JFC-like".

Key findings indicate significant differences in the dynamical behaviors between JFCs at kilometer scales and smaller meteoroids on similar orbits.

FRIPON_JFCs.csv Description

This dataset encompasses observations of 263 ''JFC-like" fireball events captured by the FRIPON (Fireball Recovery and InterPlanetary Observation Network) as part of a comprehensive study to understand the origins of meteoroids and comets in near-Earth space. Each entry in the dataset represents a unique fireball event, meticulously documented and analyzed to investigate its dynamic and orbital characteristics in relation to Jupiter-family comets (JFCs).

EFN_JFCs.csv Description

This dataset includes observations from 213 "JFC-like" fireball events recorded by the European Fireball Network (EFN) between 2017-2018. This is a subset of a larger 824 fireball datset, as described in Borovicka et al. (2022).

MORP_JFCs.csv Description

This dataset presents observations from 49 "JFC-like" fireball events recorded by the Meteorite Observation and Recovery Project (MORP) in Western Canada, emphasizing their analysis in relation to Jupiter-family comets (JFCs). The MORP project, operational from 1971 to 1985, aimed to systematically observe bright meteors to facilitate meteorite recovery and understand their pre-collision orbits.

The full MORP dataset can be found within Campbell-Brown & Hildebrand (2004) and the alpha-bet reduction in Gritsevich et al. (2009). 







DFN_JFCs.csv Description

This dataset contains detailed observations of 122 "JFC-like" fireball events captured by the Desert Fireball Network (DFN), focusing on their orbital dynamics and potential associations with Jupiter-family comets (JFCs). The DFN, a globally extended observational network initially covering the Australian outback, aims to photographically capture fireballs to analyze their trajectories, velocities, and orbits.





NASA_Horizons_JFCs_no_frags.csv Description

This dataset features information on 661 Jupiter-family comets (JFCs), derived from the NASA HORIZONS database. The JFCs are characterized by their Tisserand parameter relative to Jupiter, which falls within the range of 2 < TJ < 3, excluding cometary fragments.
