DA white dwarfs from the LSS-GAC survey DR1: the preliminary luminosity and mass functions and formation rate [PDF]

, 2015
Modern large-scale surveys have allowed the identification of large numbers of white dwarfs. However, these surveys are subject to complicated target selection algorithms, which make it almost impossible to quantify to what extent the observational ...

A new magnetic white dwarf : PG2329+267 [PDF]

, 1997
We have discovered that the white dwarf PG 2329+267 is magnetic, and assuming a centered dipole structure, has a dipole magnetic field strength of approximately 2.3MG.

Double White Dwarf Merger Products among High-mass White Dwarfs [PDF]

Astrophysical Journal, 2019
Double white dwarf (double-WD) binaries may merge within a Hubble time and produce high-mass WDs. Compared to other high-mass WDs, the double-WD merger products have higher velocity dispersion because they are older.

White-Dwarf Asteroseismology With the Kepler Space Telescope

Frontiers in Astronomy and Space Sciences, 2020
In the course of their evolution, white-dwarf stars go through at least one phase of variability in which the global pulsations they undergo allow astronomers to peer into their interiors, making it possible to shed light on their deep inner structure ...

The Pan-STARRS1 Planet Survey: Overview and first results

EPJ Web of Conferences, 2013
The Pan-STARRS1 Planet Survey (Pan-Planets) is a search for transiting extra-solar planets in the Galactic disk with a focus on planets around M-dwarfs and 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 ...

On the Radial Distribution of White Dwarfs in the Globular Cluster NGC 6397

, 2007
We have examined the radial distribution of white dwarfs over a single HST/ACS field in the nearby globular cluster NGC 6397. In relaxed populations, such as in a globular cluster, stellar velocity dispersion, and hence radial distribution, is directly ...

White dwarfs and Galactic dark matter [PDF]

, 2002
We discuss the recent discovery by Oppenheimer et al (2001) of old, cool white dwarf stars, which may be the first direct detection of Galactic halo dark matter.

Co‐overexpression of the caloric restriction‐induced mitochondrial factors PGC‐1α and MIPEP upregulates Phospho1 expression in adipocytes

FEBS Open Bio, EarlyView.
Caloric restriction that extends lifespan induces the expression of PGC‐1α and MIPEP in white adipose tissue. In this study, co‐overexpression of Pgc‐1α and Mipep upregulated the gene expression of PHOSPHO1. These findings provide new insights into mitochondria‐related mechanisms underlying the effects of caloric restriction in adipocytes.
