Water Parameters and Hydrodynamics in Rivers and Caves Hosting Astyanax mexicanus Populations Reveal Macro-, Meso- and Microhabitat Characteristics. [PDF]

open access: yesEcol Evol
From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...

Cataclysmic Variable Stars [PDF]

open access: yesInternational Astronomical Union Colloquium, 1984
AbstractThe properties of cataclysmic variable outbursts are reviewed, and interpreted in terms of dynamical instabilities by the red component, and subsequent evolution of the white dwarf accretion disc subject to a mass transfer burst in the transfer stream.

Evolution and Outbursts of Cataclysmic Variables

open access: yesActa Polytechnica CTU Proceedings, 2015
Mass transfer and accretion are very important to understand the evolution and observational properties of cataclysmic variables (CVs). Due to the lack of an accretion disk, eclipsing profiles of polars are the best source to study the character of mass ...

The Magnetospheric Boundary in Cataclysmic Variables

open access: yesEPJ Web of Conferences, 2014
The magnetic cataclysmic variables (MCVs) present a wealth of observational diagnostics for studying accretion flows interacting with a magnetosphere. Spin-period pulsations from the rotation of the white dwarf are seen in optical light, in the UV and X ...

High-Speed Photo-Polarimetry of Magnetic Cataclysmic Variables

open access: yesActa Polytechnica CTU Proceedings, 2015
I review recent highlights of the SAAO High-speed Photo-POlarimeter (HIPPO) on the study of magnetic Cataclysmic Variables. Its high-speed capabilities are demonstrated with example observations made of the intermediate polar NY Lup and the polar ...
