Numerical simulations of the convective dilution process in helium-rich white dwarfs [PDF]

, 2018
The 21st European Workshop on White Dwarfs was held in Austin, TX from July 23rd to 27th of 2018DB and DBA white dwarfs are generally believed to be the result of a process by which a thin radiative hydrogen atmosphere floating in diffusive equilibrium

35 Individuals With HUWE1‐Related Neurodevelopmental Disorder and Suggested Clinical Evaluations

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT HUWE1 (HECT, UBA, and WWE Domain Containing E3 Ubiquitin Protein Ligase1, OMIM 300697), located at Xp11.22, encodes a ubiquitin ligase that is highly conserved across species. Genetic variants in HUWE1 described in multiple independent studies cause X‐linked intellectual disability, including in the patients identified by Juberg, Marsidi, and ...

Do White Dwarfs Sample Water-rich Planetary Material?

The Astrophysical Journal
Polluted white dwarfs offer a unique way to directly probe the compositions of exoplanetary bodies. We examine the water content of accreted material using the oxygen abundances of 51 highly polluted white dwarfs.

Research Paper: The Effect of the Generalized Uncertainty Principle with Maximum Length on the Size of White Dwarfs [PDF]

فیزیک کاربردی ایران
The challenge in developing a theory of quantum gravity stems from the fundamentally different ways the two theories describe physical systems. Quantum mechanics operates on discrete, probabilistic principles, while general relativity is a continuous ...

Gaia photometry for white dwarfs [PDF]

, 2014
Context. White dwarfs can be used to study the structure and evolution of the Galaxy by analysing their luminosity function and initial mass function. Among them, the very cool white dwarfs provide the information for the early ages of each population ...

The Insistence of Blackness and the Persistence of Antiblackness in Ireland

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

Novel Atmospheric Dynamics Shape the Inner Edge of the Habitable Zone around White Dwarfs

The Astrophysical Journal
White dwarfs offer a unique opportunity to search nearby stellar systems for signs of life, but the habitable zone around these stars is still poorly understood.

An overview of white dwarf stars

EPJ Web of Conferences, 2013
We present a brief summary of what is currently known about white dwarf stars, with an emphasis on their evolutionary and internal properties. As is well known, white dwarfs represent the end products of stellar evolution for the vast majority of stars ...

Advances in Chitosan Nanoparticles: A Comprehensive Review of Properties, Synthesis, Characterization, Multidisciplinary Applications, and Future Perspectives

Journal of Applied Polymer Science, EarlyView.
This review highlights the synthesis of chitosan nanoparticles from natural sources, the thorough characterization of them, and use of microscopic and spectroscopic methods. It emphasizes that it has some indispensable properties such as being non‐toxic, antimicrobial, and capable of controlled drug release.

White dwarf cooling sequences and cosmochronology

EPJ Web of Conferences, 2013
The evolution of white dwarfs is a simple gravothermal process. This means that their luminosity function, i.e. the number of white dwarfs per unit bolometric magnitude and unit volume as a function of bolometric magnitude, is a monotonically increasing ...
