Болід [Bolid]

open access: yes, 2004
БОЛІ́Д (від грец. βολίς – метальний спис) – яскравий метеор, блиск якого при спостереженні з Землі перевищує блиск планети Венера. Тому яскраві Б. можна спостерігати і вдень. Б. – тверді космічні частинки, які входять у земну атмосферу зі швидкістю від 11 до 72 км/сек. і мають ма... ⚠️ Цей запис містить лише бібліографічні метадані.

Situating African FinTech in Global Financial Networks

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
Short Abstract This paper explores the geographical patterns of firm creation and investments in African FinTech and how they have evolved since the emergence of FinTech on the continent. Our findings show waves of investment, specialisation of different FinTech centres and the networks of FinTech capital.

Historical detection of atmospheric impacts by large bolides using acoustic-gravity waves [PDF]

open access: yes, 1995
During the period from about 1960 to the early 1980`s a number of large bolides (meteor-fireballs) entered the atmosphere which were sufficiently large to generate blast waves during their drag interaction with the air.

Second‐Scale Formation of Non‐Field‐Aligned Plasma Irregularities Observed From a High‐Altitude 43‐Cassiopeiids Fireball

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract High‐altitude optical meteors initiating above 150 km are exceedingly rare, with confirmed observations largely confined to the Leonids. Using the Meteor and ionospheric Irregularity Observation System, we recorded a bright 43‐Cassiopeiids fireball with heterogeneous material. It initiated luminously at an exceptional altitude of 157.8 ± $\pm $

Weather Radar Detection and Analysis of Bolides in the Day or Night

open access: yesAdvances in Astronomy
Weather radars have proven to be valuable tools for detection and analysis of meteorite falls, specifically identifying and analyzing falling meteorites which have survived the initial fireball.

Characterizing Patterns of Resurfacing on Venus With Volcanoes and Coronae

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract One of the major research questions for Venus is the manner in which it resurfaces itself, with a near‐random distribution of a relatively few craters providing the only age constraints for the planet's surface. We use volcanoes and their temporal and spatial relationships to coronae to characterize patterns of coronal resurfacing for ...

PFN report on field meteorite search in period 2018–2020 [PDF]

open access: yes, 2021
Since 2010, the Meteorite Section of the Comet and Meteor Workshop (PKiM) has been systematically organizing exploratory expeditions to selected meteorite strewn fields, calculated from bolides registered with the Polish Fireball Network (PFN).
