Measuring the Mass–Radius Relation of White Dwarfs Using Wide Binaries

The Astrophysical Journal
Measuring the mass–radius relation of individual white dwarfs is an empirically challenging task that has been performed for only a few dozen stars. We measure the white dwarf mass–radius relation using the gravitational redshifts and radii of 135 white ...

White Dwarf Period Tables I. Pulsators with hydrogen-dominated atmospheres [PDF]

, 2016
We aimed at collecting all known white dwarf pulsators with hydrogen-dominated atmospheres and list their main photometric and atmospheric parameters together with their pulsation periods and amplitudes observed at different epochs.

Functional tooth unit, periodontal status, and association with weight change in older adults

Journal of Periodontology, EarlyView.
Abstract Background Literature reports that having fewer teeth is associated with reduced chewing capacity, which in turn may lead to weight changes due to diminished oral functionality. This study aims to assess the association between functional tooth units (FTU) and periodontal status and weight change among older adults participating in the Health,

A Massive White Dwarf or Low-mass Neutron Star Discovered by LAMOST

The Astrophysical Journal
We report the discovery of a close binary J0606+2132 (Gaia DR3 3423365496448406272) with P _obs = 2.77 days containing a possible massive white dwarf (WD) or a neutron star (NS) using LAMOST spectroscopic data.

Farming in the shadows of Rome: A multi‐proxy palaeoenvironmental record from Loch Clunie—Perthshire

Journal of Quaternary Science, EarlyView.
ABSTRACT Roman impacts on local society is a subject of international significance. Loch Clunie, Perthshire, lies only 5.4 km from Inchtuthil, the only Roman legionary fortress in Scotland, and contains two crannogs and a probable lakeside hillfort. Despite this proximity and the likelihood of local–Roman interaction, these sites remain unexcavated ...

Novel Atmospheric Dynamics Shape the Inner Edge of the Habitable Zone around White Dwarfs

The Astrophysical Journal
White dwarfs offer a unique opportunity to search nearby stellar systems for signs of life, but the habitable zone around these stars is still poorly understood.

Fermentation characteristics of four southern sichuan citrus cultivars

JSFA reports, EarlyView.
Abstract Background Sichuan, China's leading citrus‐producing region has strong potential for citrus wine development. Citrus is rich in bioactive compounds that enhance flavor and health value, yet current citrus wines often show weak aroma and bitterness.

Hunting for Polluted White Dwarfs and Other Treasures with Gaia XP Spectra and Unsupervised Machine Learning

The Astrophysical Journal
White dwarfs (WDs) polluted by exoplanetary material provide the unprecedented opportunity to directly observe the interiors of exoplanets. However, spectroscopic surveys are often limited by brightness constraints, and WDs tend to be very faint, making ...

Lessons for asteroseismology from white dwarf stars

, 2005
. The interpretation of pulsation data for sun-like stars is currently facing challenges quite similar to those faced by white dwarf modelers ten years ago.

Experiences of Drainage and Associated Impacts: A Qualitative Study Among Patients With Hidradenitis Suppurativa

JEADV Clinical Practice, EarlyView.
This study provides an in‐depth account of patients' experiences of drainage as a symptom of hidradenitis suppurativa. The HIDE Scale© facilitates incorporation of these insights into clinical practice, supporting person‐centred approaches that enhance clinical assessment, reduce stigma, and strengthen patient–clinician communication.
