On the Proposed Interstellar Origin of the USG 20140108 Fireball [PDF]

The Astrophysical Journal, 2023
A critical review of the evidence for the interstellar origin of the USG 20140108 fireball is presented. Examining United States Government (USG) fireball velocities where independent data are available shows the former to have significant (10–15 km s ...

A Global Fireball Observatory [PDF]

Planetary and Space Science, 2020
The world’s meteorite collections contain a very rich picture of what the early Solar System would have been made of, however the lack of spatial context with respect to their parent population for these samples is an issue. The asteroid population is equally as rich in surface mineralogies, and mapping these two populations (meteorites and asteroids ...

Expanding Fireball in Magnetar Bursts and Fast Radio Bursts [PDF]

Monthly notices of the Royal Astronomical Society, 2022
A fireball of radiation plasma created near the surface of a neutron star (NS) expands under its own pressure along magnetic field lines, and produces photon emission and relativistic matter outflow.

Data on 824 fireballs observed by the digital cameras of the European Fireball Network in 2017-2018. II. Analysis of orbital and physical properties of cm-sized meteoroids [PDF]

Astronomy & Astrophysics, 2022
Meteoroids impacting the Earth on a daily basis are fragments of asteroids and comets. By studying fireballs produced during their disintegration in the atmosphere, we can gain information about their source regions and the properties of their parent ...

Accurate 3D fireball trajectory and orbit calculation using the 3D-firetoc automatic Python code [PDF]

Monthly notices of the Royal Astronomical Society, 2021
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 ...

GRB 210121A: A Typical Fireball Burst Detected by Two Small Missions [PDF]

Astrophysical Journal, 2021
The Chinese CubeSat Mission, Gamma Ray Integrated Detectors (GRID), recently detected its first gamma-ray burst, GRB 210121A, which was jointly observed by the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM). This burst
