Wide Binaries with White Dwarf or Neutron Star Companions Discovered from Gaia DR3 and LAMOST

open access: yesThe Astrophysical Journal
The Gaia Data Release 3 (DR3) mission has identified and provided about 440,000 binary systems with orbital solutions, offering a valuable resource for searching binaries including a compact component.

Laryngeal Dysfunction Following COVID‐19: A TriNetX Retrospective Cohort Study

open access: yesThe Laryngoscope, EarlyView.
COVID‐19 is associated with an increased incidence of new‐onset laryngeal dysfunction, including chronic cough, dysphagia, voice disorders, vocal fold paralysis, and laryngeal spasm, compared with uninfected controls. Risk peaks one to two years after infection for most outcomes and is influenced by factors such as hospitalization, mechanical ...

Asteroseismology of white dwarf stars

open access: yes, 2014
Most of low- and intermediate-mass stars that populate the Universe will end their lives as white dwarf stars. These ancient stellar remnants have encrypted inside a precious record of the evolutionary history of the progenitor stars, providing a wealth of information about the evolution of stars, star formation, and the age of a variety of stellar ...

Convergence Deficits in Myoclonus‐Dystonia Point to Cerebellar Impairment

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

SN 2022oqm: A Bright and Multipeaked Calcium-rich Transient

open access: yesThe Astrophysical Journal
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multipeaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kpc from its host galaxy, the face-on spiral galaxy NGC 5875.

The Physics of Pulsating White Dwarf Stars

open access: yes, 2012
We present a summary of the properties of white dwarf stars, beginning with a brief reminder of their basic characteristics. We continue with a discussion of the spectral types, evolution, and other properties of cooling white dwarfs, with an emphasis on

Methods for Uncertainty Quantification in Dictionary Matching to Advance Reliability of Quantitative MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Aims Purpose: Dictionary matching is a standard tool in quantitative MRI (qMRI), but typically lacks uncertainty quantification (UQ). This is critical when advanced reconstructions (e.g., compressed sensing, deep learning) introduce complex‐valued, spatially varying, and temporally correlated noise that violates standard assumptions of ...

New white dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 12 [PDF]

open access: yes, 2016
We report the discovery of 6576 new spectroscopically confirmed white dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 12. We obtain Teff, log g and mass for hydrogen atmospherewhite dwarf stars (DAs) and helium atmospherewhite dwarf

Simultaneous T2, T2*, and R2′ Mapping for Multiple Sclerosis Using Nonlinear Model‐Based Reconstruction of Undersampled Radial RARE‐EPI MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To demonstrate the synergy of undersampled radial 2in1‐RARE‐EPI acquisition and nonlinear model‐based reconstruction for accelerated and simultaneous T2, T2*, and R2′ mapping in brains of patients with multiple sclerosis (MS). Methods 2in1‐RARE‐EPI combines a RARE module with an EPI module to capture T2 and T2* information.

89 New Ultracool Dwarf Comoving Companions Identified with the Backyard Worlds: Planet 9 Citizen Science Project

open access: yesThe Astronomical Journal
We report the identification of 89 new systems containing ultracool dwarf companions to main-sequence stars and white dwarfs, using the citizen science project Backyard Worlds: Planet 9 and cross-reference between Gaia and CatWISE2020.
