Deciphering the Palaeocene-Eocene thermal maximum by Granger causality test

Geosystems and Geoenvironment, 2023
The Palaeocene-Eocene thermal maximum is a global warming period (∼56 Ma), which is marked by a sharp negative carbon isotope excursion (CIE) that caused by the injection of massive isotopically-light carbon into the ocean-atmosphere.

The 2011 October Draconids Outburst. II. Meteoroid Chemical Abundances from Fireball Spectroscopy [PDF]

, 2013
On October 8, 2011 the Earth crossed dust trails ejected from comet 21P/Giacobini-Zinner in the late 19th and early 20th Century. This gave rise to an outburst in the activity of the October Draconid meteor shower, and an international team was organized

Shoemaker-Levy 9 Impact Modeling: I. High-Resolution 3D Bolides

, 2006
We have run high-resolution, three-dimensional, hydrodynamic simulations of the impact of comet Shoemaker-Levy 9 into the atmosphere of Jupiter. We find that the energy deposition profile is largely similar to the previous two-dimensional calculations of

Towards the azimuthal characteristics of ionospheric and seismic effects of "Chelyabinsk" meteorite fall according to the data from coherent radar, GPS and seismic networks

, 2015
We present the results of a study of the azimuthal characteristics of ionospheric and seismic effects of the meteorite 'Chelyabinsk', based on the data from the network of GPS receivers, coherent decameter radar EKB SuperDARN and network of seismic ...

Aquatic refuges for surviving a global catastrophe [PDF]

, 2017
Recently many methods for reducing the risk of human extinction have been suggested, including building refuges underground and in space. Here we will discuss the perspective of using military nuclear submarines or their derivatives to ensure the ...

Bolides

, 2022
The composition of Bolides acts somewhat like a series of snapshots or a diary of my life between March 2020 and December 2021, and for me evokes geographical and temporal cues that are very specific for that particular point in time. The source material includes underwater recordings of kelp forests, captured by homemade hydrophones, the ululations of

Geomagnetic effect of the Bering Sea meteoroid

Russian Journal of Earth Sciences, 2020
Possibilities of studies of the geomagnetic effects produced by the interaction of a cosmic bodies with the magnetosphere-ionosphere-atmosphere system are very limited due to extremely small number of examined events.

Discovery of a new branch of the Taurid meteoroid stream as a real source of potentially hazardous bodies

, 2017
Taurid meteor shower produces prolonged but usually low activity every October and November. In some years, however, the activity is significantly enhanced.

BLADE: An Automated Framework for Classifying Light Curves from the Center for Near-Earth Object Studies Fireball Database

The Astronomical Journal
Fireballs (bolides) are high-energy luminous phenomena produced when meteoroids and small asteroids enter Earth’s atmosphere at hypersonic speeds, often resulting in fragmentation or complete disintegration accompanied by significant energy release.

In situ single‐spot Rb/Sr cosmochronology of roedderite in the Ribbeck aubrite (asteroid 2024 BX1)

Meteoritics &Planetary Science, EarlyView.
Abstract The mineralogy and textures of several fragments from the Ribbeck aubrite were analyzed using a combination of scanning electron microscopy, electron microprobe analysis, μRaman spectroscopy, and laser ablation inductively coupled reaction cell mass spectrometry (LA‐ICP‐MS/MS).
