The Exoplanet Handbook
TL;DR: In this paper, the authors present an overview of the solar system and its evolution, including the formation and evolution of stars, asteroids, and free-floating planets, as well as their internal and external structures.

TL;DR: In this paper, a catalogue of white dwarf candidates selected from the second data release of Gaia (DR2) is presented, consisting of 486641 stars with calculated probability of being a white dwarf (PWD) for all Gaia sources that passed the initial selection.
Journal ArticleDOI
Ancient planetary systems are orbiting a large fraction of white dwarf stars
TL;DR: In this article, atmospheric pollution by various elements heavier than helium has been used to infer that a comparable fraction of the white dwarf descendants of such main-sequence stars are orbited by planetary systems, and for plausible planetary system configurations, this total mass is likely to be at least equal to that of the Sun's asteroid belt.
Journal ArticleDOI
The chemical diversity of exo-terrestrial planetary debris around white dwarfs
TL;DR: In this article, the authors presented the HST ultraviolet spectra of the white dwarfs PG 0843+516, PG 1015+161, SDSS 1228+1040, and GALEX 1931+0117, which accrete circumstellar planetary debris formed from the destruction of asteroids.
Journal ArticleDOI
Magnetic White Dwarfs
TL;DR: In this article, the current status of research on the observational and theoretical characteristics of isolated and binary magnetic white dwarfs (MWDs) is reviewed, and a review of the existing literature is presented.

Comprehensive analytic formulae for stellar evolution as a function of mass and metallicity
TL;DR: In this article, the authors present analytic formulae that approximate the evolution of stars for a wide range of mass M and metallicity Z, including all phases from the zero-age main sequence up to, and including, the remnant stages.
Journal ArticleDOI
Non-LTE line-blanketed model atmospheres of hot stars. 1: Hybrid complete linearization/accelerated lambda iteration method
TL;DR: In this article, a hybrid complete linearization/accelerated lambda iretation (CL/ALI) method was proposed for non-local thermodynamic equilibrium (non-LTE) model stellar atmospheres.

TL;DR: A catalog of 9316 spectroscopically confirmed white dwarfs from the Sloan Digital Sky Survey Data Release 4 is presented in this paper, with a set of visual inspections and photometric cuts.

Are There Unstable Planetary Systems around White Dwarfs
John H. Debes,Steinn Sigurdsson +1 more
TL;DR: In this article, the authors show that when mass loss is slow, systems of two planets that are marginally stable can become unstable to close encounters, while for three planets the timescale for close approaches decreases significantly with increasing mass ratio.
