White Dwarfs in Cataclysmic Variables: An Update [PDF]

open access: yesActa Polytechnica CTU Proceedings, 2015
In this review, we summarize what is currently known about the surface temperatures of accreting white dwarfs in nonmagnetic and magnetic cataclysmic variables (CVs) based upon synthetic spectral analyses of far ultraviolet data.

Molecular Alterations in Osteosarcomas of the Oral and Maxillofacial Region: A Scoping Review. [PDF]

open access: yesJ Oral Pathol Med
ABSTRACT Background Given the rarity and aggressive nature of osteosarcomas (OS) in the oral and maxillofacial region, understanding their molecular alterations is essential to improve diagnosis, prognosis, and guide targeted therapies. This study aimed to map molecular alterations associated with oral and maxillofacial OS, providing an overview of the

Cataclysmic Variables as Supernova Ia Progenitors [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
Although the identification of the progenitors of type Ia supernovae (SNeIa) remains controversial, it is generally accepted that they originate from binary star systems in which at least one component is a carbon-oxygen white dwarf (WD); those systems ...

The Accreting White Dwarfs in Cataclysmic Variables

open access: yesGalaxies, 2022
Accreting white dwarfs (WDs) in cataclysmic variables (CVs) provide crucial insights about the accretion of mass and angular momentum in all types of binaries, including accreting NSs and BHs.

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 ...
