Strewn Field Simulations and Field Searchs of a Few Latest Bolides Over Hungary - Connection with the Fragmentation Height

open access: yes, 2019
nspired by several unsuccessful field searches on the probable fall locations, we reanal-ised a few most recently observed blowing bolides ap-peared over Hungary on: 18:47:33 UTC 8 April, 2018; 17:31:01 UTC April 06, 2015 (so-called "Easter Bo-

Preliminary results of Galileo direct imaging of S-L 9 impacts [PDF]

open access: yes, 1995
Direct Galileo imaging data were obtained of the Jupiter impact sites for Comet Shoemaker-Levy 9 fragments K, N, and W during their early, high-energy phases.

A Comparison of Automated Bolide Detection Methods

open access: yes, 2023
Bolide recording and analysis are crucial so meteoroid fragments can be found, a lightcurve analyzed, and its trajectory calculated. The Spalding Allsky Camera Network (SACN) generates videos and composite images of the night sky that are potential ...

BOLIDE PHYSICAL THEORY WITH APPLICATION TO PN AND EN FIREBALLS. [PDF]

open access: yes, 2001
Using data on 22 'precise bolides' with up to 882 individual points on their trajectories and using data on 29 'bright bolides' and on 10 artificial meteors, we tried to derive dependence of ablation and shape-density coefficients, and of luminous ...

Mass Extinctions Caused by Large Bolide Impacts

open access: yesPhysics Today, 1987
A wealth of evidence has forced my colleagues and me to conclude that 65 million years ago a mountain-sized object hit Earth and caused the extinction of most of the then existing species, bringing a close to the Cretaceous period of geological history and opening the Tertiary period. Much of the evidence for this lies in the unusual layer of clay that

Fluctuations and symmetry in the speed and direction of the jets of SS433 on different timescales

open access: yes, 2007
ABRIDGED We present new results on the variations in speed and direction of the jet bolides in the Galactic microquasar SS433, from high resolution spectra, taken with the ESO 3.6-m New Technology Telescope almost nightly over 0.4 of a precession cycle ...

Carbon source from limestone target by impact reaction at the K/T Boundary

open access: yes, 1999
Carbon found at the K/T geological boundaries can be explained by impact reaction between the K/T bolides and limestone target rocks, which are proved by other natural and artificial ...
