Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical Monograph Series, Page 133-151., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

ANALYSIS OF ASTEROID’S OBSERVATIONS IN OPEN PHOTOMETRIC DATABASES

open access: yesOdessa Astronomical Publications, 2016
Today there are several open photometric databases containing important information for the study of the physical properties of asteroids. These databases are based on the results of various measurements of the different sets of objects.

Inelastic Dissipation in Wobbling Asteroids and Comets [PDF]

open access: yes, 1998
Asteroids and comets dissipate energy when they rotate about the axis different from the axis of the maximal moment of inertia. We show that the most efficient internal relaxation happens at the double frequency of body's tumbling.

Mitogenomics provides new insights into the phylogenetic relationships and evolutionary history of deep-sea sea stars (Asteroidea)

open access: yesScientific Reports, 2022
The deep sea (> 200 m) is considered as the largest and most remote biome, which characterized by low temperatures, low oxygen level, scarce food, constant darkness, and high hydrostatic pressure.

Asteroid family identification using the Hierarchical Clustering Method and WISE/NEOWISE physical properties [PDF]

open access: yes, 2013
Using albedos from WISE/NEOWISE to separate distinct albedo groups within the Main Belt asteroids, we apply the Hierarchical Clustering Method to these subpopulations and identify dynamically associated clusters of asteroids. While this survey is limited

Aqueous alteration on main belt primitive asteroids: results from visible spectroscopy

open access: yes, 2014
This work focuses on the study of the aqueous alteration process which acted in the main belt and produced hydrated minerals on the altered asteroids.
