Understanding white dwarf binary evolution with white dwarf/main sequence binaries: first results from SEGUE [PDF]
arXiv, 2006 Close white dwarf binaries make up a wide variety of objects such as double white dwarf binaries, which are possible SN Ia progenitors, cataclysmic variables, super soft sources, or AM CVn stars. The evolution and formation of close white dwarf binaries crucially depends on the rate at which angular momentum is extracted from the binary orbit.

A wide binary trigger for white dwarf pollution [PDF]
, 2015 Metal pollution in white dwarf atmospheres is likely to be a signature of remnant planetary systems. Most explanations for this pollution predict a sharp decrease in the number of polluted systems with white dwarf cooling age. Observations do not confirm this trend, and metal pollution in old (1-5 Gyr) white dwarfs is difficult to explain.

White dwarf dynamical interactions
, 2023 Merging white dwarfs is a promising channel to trigger Type Ia supernovae, known as the double degenerate scenario. Supernovae are stellar explosions that radiate as much energy as any ordinary star is expected to emit over its entire life span, outshining briefly the whole hosting galaxy.

International Journal of Eating Disorders, EarlyView.ABSTRACT Objective Having both an eating disorder (ED) and borderline personality disorder (BPD) is associated with heightened clinical complexity, high levels of distress, and challenges in treatment. This study sought to qualitatively investigate the experiences of women with an ED and comorbid BPD as they undergo ED treatment, aiming to better ...

The Astrophysical JournalIRAS 00500+6713 is a hypothesized remnant of a Type Iax supernova SN 1181. Multiwavelength observations have revealed its complicated morphology; a dusty infrared ring is sandwiched by the inner and outer X-ray nebulae. We analyze the archival X-ray data

KIC 4552982: outbursts and pulsations in the longest-ever pseudo-continuous light curve of a ZZ Ceti
EPJ Web of Conferences, 2015 KIC 4552982 was the first ZZ Ceti (hydrogen-atmosphere pulsating white dwarf) identified to lie in the Kepler field, resulting in the longest pseudo-continuous light curve ever obtained for this type of variable star.

, 2010 White dwarfs are almost completely degenerate objects that cannot obtain energy from the thermonuclear sources and their evolution is just a gravothermal process of cooling. The simplicity of these objects, the fact that the physical inputs necessary to understand them are well identified, although not always well understood, and the impressive ...

Feminist Anthropology, EarlyView.Abstract Pre‐exposure prophylaxis (PrEP) is an antiretroviral drug that effectively prevents an HIV infection, which German statutory health insurance has covered since 2019. The drug's use in Germany has (re)surfaced ambivalent emotions: hopes for an HIV/AIDS‐free future and sexual liberation rub against enduring worries and moralizations of ...
