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 ...

The Formation Rate, Mass and Luminosity Functions of DA White Dwarfs from the Palomar Green Survey

, 2004
Spectrophotometric observations at high signal-to-noise ratio were obtained of a complete sample of 347 DA white dwarfs from the Palomar Green (PG) Survey. Fits of observed Balmer lines to synthetic spectra calculated from pure-hydrogen model atmospheres

A search for variable white dwarfs in large area time domain surveys: a pilot study in SDSS Stripe 82 [PDF]

, 2015
We present a method to reliably select variable white dwarfs from large area time domain surveys and apply this method in a pilot study to search for pulsating white dwarfs in the Sloan Digital Sky Survey Stripe 82.

Large‐Scale Quantitative Morphometry of Platelet α‐Granules via SIM Super‐Resolution Microscopy for Cancer Liquid Biopsy

Advanced Science, EarlyView.
ABSTRACT Blood‐based liquid biopsies hold transformative potential for non‐invasive cancer management, but current approaches relying on rare circulating tumor components limit their broad clinical utility. Platelets, abundant in blood and mediating diverse cancer‐associated responses, represent a compelling yet largely unexplored alternative.

White Dwarfs

Le Journal de Physique Colloques, 1980
The thermal properties and neutrino emissivity of matter in the dense, degenerate cores of white dwarfs, together with efficient heat transport through the high-density envelopes of these stars, affect the theoretical white dwarf luminosity function.

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.

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 ...

The white dwarf cooling sequence of NGC 6791: a unique tool for stellar evolution [PDF]

, 2011
NGC 6791 is a well-studied, metal-rich open cluster that is so close to us that can be imaged down to luminosities fainter than that of the termination of its white dwarf cooling sequence, thus allowing for an in-depth study of its white dwarf population.

Comparative Insights and Overlooked Factors of Interphase Chemistry in Alkali Metal‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review presents a comparative analysis of Li‐, Na‐, and K‐ion batteries, focusing on the critical role of electrode–electrolyte interphases. It especially highlights overlooked aspects such as SEI/CEI misconceptions, binder effects, and self‐discharge relevance, emphasizing the limitations of current understanding and offering strategies for ...
