A Precise Radial Velocity Search for Giant Planets orbiting polluted White Dwarfs [PDF]
, 2018 The 21st European Workshop on White Dwarfs was held in Austin, TX from July 23rd to 27th of 2018We present a feasibility study for extending the well-known radial velocity technique to search for planetary companions around white dwarfs.

Universe, 2023 In 1995, Glendenning, Kettner and Weber postulated the existence of a new class of compact stars resembling white dwarfs but containing a small strange quark-matter core surrounded by hadronic layers attaining much higher densities than those found in ...

The DB gap and a new class of pulsating white dwarfs
EPJ Web of Conferences, 2013 The recent systematic surveys providing enormously massive datasets of white dwarfs show that there is still a deficit of a factor of 2.5 in the DA/non-DA ratio within the temperature range of 30 000 K < Teff < 45 000 K, which has been regarded as the ...

Stellar equilibrium configurations of white dwarfs in the f(R, T) gravity
European Physical Journal C: Particles and Fields, 2017 In this work we investigate the equilibrium configurations of white dwarfs in a modified gravity theory, namely, f(R, T) gravity, for which R and T stand for the Ricci scalar and trace of the energy-momentum tensor, respectively.

A White Dwarf Search Model Based on a Deep Transfer-learning Method
The Astrophysical Journal Supplement Series, 2023 White dwarfs represent the ultimate stage of evolution for over 97% of stars and play a crucial role in studies of the Milky Way’s structure and evolution.

The Influence of Tidal Heating on the Habitability of Planets Orbiting White Dwarfs
The Astrophysical Journal Letters, 2023 In recent years, there have been a growing number of observations indicating the presence of rocky material in short-period orbits around white dwarfs. In this Letter, we revisit the prospects for habitability around these post-main-sequence star systems.

White Dwarf Cooling Curves and Searches For White Dwarfs [PDF]
Highlights of Astronomy, 1998 White dwarf (WD) evolution is essentially a cooling problem in two parts. Degenerate electrons in the core provide the support while non-degenerate C and O ions provide the thermal reservoir (Koester & Chanmugam 1990, Kawaler 1996). The rate of energy loss through the non-degenerate envelope of H and He—segregated by gravitational settling—is ...

Immune Checkpoint Inhibitor–Related Myositis and Associated Triad Overlap Syndrome
Arthritis Care &Research, EarlyView.Objective Immune checkpoint inhibitor (ICI) myositis is a rare but a highly morbid condition, particularly with the ICI myositis triad syndrome of myositis, myocarditis, and myasthenia gravis. We report the clinical characteristics of ICI myositis and all‐cause mortality in these patients.

Effects of modified gravity on microscopic properties and cooling timescale of white dwarfs
Physics Letters BThere are currently two open questions in white dwarf physics: why are massive dwarfs observed less often in astronomical surveys, and why have not any super-Chandrasekhar white dwarfs been found despite the discovery of more than a dozen peculiar ...
