Cataclysmic variables: structure and evolution [PDF]

International Astronomical Union Colloquium, 1994
AbstractI discuss the structure and evolution of cataclysmic variables, with a particular emphasis on the influence of the physics used in calculating the internal structure of the secondary. The available observational data is very rich, and can, in principle, be used to constrain the stellar physics.

Brown dwarfs in retrogradely precessing cataclysmic variables?

EPJ Web of Conferences, 2011
We compare Smoothed Particle Hydrodynamic simulations of retrogradely precessing accretion disks that have a white dwarf primary and a main sequence secondary with observational data and with theory on retrograde precession via tidal torques like those ...

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

Safety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Benefitting from brutality? Profits of north‐western Europe's slave trade at the eve of the industrial revolution

The Economic History Review, EarlyView.
Abstract One of the most contentious issues in the study of the Atlantic slave trade is the profitability of the trade. In this paper, we contribute by pooling all available data on transatlantic slave ship voyage accounts into a joint dataset. This dataset includes data from a period of 100 years (1730–1830) and from five nations (Denmark, France ...

Thinking and Talking About War: How the Public in Six Countries Discusses the Outbreak of the War in Ukraine

JCMS: Journal of Common Market Studies, EarlyView.
Abstract The Russian aggression in Ukraine, launched on 24 February 2022, marked the return of conventional war in the European continent. While Western leaders have framed the ongoing conflict through a common narrative when speaking internationally, which varies in its national nuances, much less is known about the images and lenses that the European

The Evolution of Cataclysmic Variables [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractUsing Eggletons code the evolution of cataclysmic variables (CVs) is investigated. CVs might suffer the loss of mass and angular momentum during their evolution, we present the models of CVs with mass loss and angular momentum loss (AML) due to gravitation wave radiation (GR) and/or magnetic braking (MB).

Decoding the Hot‐Mitochondrion Paradox

BioEssays, Volume 48, Issue 7, July 2026.
A distributed mechanism of mitochondrial heat generation is proposed in which all ion‐translocating proteins embedded within the inner mitochondrial membrane contribute to localized heat generation. All ion‐translocating proteins embedded within the inner mitochondrial membrane (IMM)—with ATP synthase shown here as an example—are proposed to function ...

BLOB PARAMETERS OF ACCRETION STREAMS IN MAGNETIC CATACLYSMIC VARIABLES

Odessa Astronomical Publications, 2017
Results of investigations of the autocorrelation functions for two magnetic cataclysmic variables BY Cam and QQ Vul are presented. Significant variations of this characteristic are detected. They are interpreted as caused by variations of the blob length

Spectroscopically Identified Cataclysmic Variables from the LAMOST Survey. II. Period Estimates

The Astronomical Journal, 2023
We examine a sample of 340 cataclysmic variables (CVs) from the latest data release of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey, along with 18 objects that are newly classified as CVs.
