Electromagnetic Characterization of the LISA Verification Binary ZTF J0526+5934
The Astrophysical Journal, 2023 We present an analysis of new and archival data to the 20.506 minute LISA verification binary J052610.42+593445.32 (J0526+5934). Our joint spectroscopic and photometric analysis finds that the binary contains an unseen M _1 = 0.89 ± 0.11 M _⊙ CO-core ...

A wide binary trigger for white dwarf pollution
, 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

Prospects for detection of detached double white dwarf binaries with Gaia, LSST and LISA [PDF]
, 2017 Double white dwarf (DWD) binaries are expected to be very common in the Milky Way, but their intrinsic faintness challenges the detection of these systems. Currently, only a few tens of detached DWDs are know.

A Young Ultramassive White Dwarf in the AB Doradus Moving Group [PDF]
Astrophysical Journal, 2018 We use Gaia Data Release 2 (DR2) kinematic data and white dwarf evolutionary models to determine that the young and ultramassive 1.28 ± 0.08 M⊙ white dwarf GD 50 is a likely member of the AB Doradus moving group (ABDMG).

An Out‐of‐Place Etiology: Recognizing FMR1 Premutation in the Memory Clinic
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT The FMR1 gene premutation (55–200 CGG repeats) is usually associated with a wide range of symptoms and phenotypes within the Fragile X‐tremor/ataxia syndrome (FXTAS), but may also manifest as predominant or isolated cognitive decline. We describe three male patients referred for progressive cognitive impairment and behavioral changes. Standard

Eclipsing binary and white dwarf features associated with K2 target EPIC251248385 [PDF]
, 2019 White dwarfs, remnants of Sun-like stars which have completed their evolution, are one of the most common types of stars in space. Despite this, very few white dwarfs have been observed in transiting or eclipsing systems, and only two planetary systems ...

The demographics of neutron star – white dwarf mergers [PDF]
Astronomy & Astrophysics, 2018 Context. The mergers of neutron stars (NSs) and white dwarfs (WDs) could give rise to explosive transients, potentially observable with current and future transient surveys.

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications
Advanced Functional Materials, EarlyView.Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

White Dwarfs in Wide Binaries: The Strong Effects of Stellar Evolution and Mass Loss
The Astrophysical JournalWe examine the statistics of main-sequence/main-sequence, main-sequence/white-dwarf, and white-dwarf/white-dwarf wide binaries at 10 ^2.5 –10 ^4 au separations in Gaia data.

A consistency test of white dwarf and main sequence ages: NGC 6791
EPJ Web of Conferences, 2013 NGC 6791 is an open cluster that it is so close to us that can be imaged down to very faint luminosities. The main sequence turn-off age (∼8 Gyr) and the age derived from the cut-off of the white dwarf luminosity function (∼6 Gyr) were found to be ...
