Using 3.4 μm Variability toward White Dwarfs as a Signpost of Remnant Planetary Systems

The Astrophysical Journal
Roughly 2% of white dwarfs harbor planetary debris disks detectable via infrared excesses, but only a few percent of these disks show a gaseous component, distinguished by their double-peaked emission at the near-infrared calcium triplet.

A Systematic Review of the Clinical Impact of Implementing Artificial Intelligence in Upper Aerodigestive Tract Endoscopy

Head &Neck, EarlyView.
ABSTRACT Background Endoscopy is essential in upper aerodigestive tract (UADT) examination, particularly in the early detection of laryngopharyngeal lesions. However, UADT endoscopy remains operator‐dependent and lacks standardized quality metrics. Recent advancements in artificial intelligence (AI) have generated interest in applications within UADT ...

A Test of Spectroscopic Age Estimates of White Dwarfs Using Wide WD+WD Binaries

The Astrophysical Journal
White dwarf stars have been used for decades as precise and accurate age indicators. This work presents a test of the reliability of white dwarf total ages when spectroscopic observations are available. We conduct follow-up spectroscopy of 148 individual

Evidence for very nearby hidden white dwarfs

, 2016
We report the discovery of a tertiary component to the prominent and nearby (d = 14 pc) visual binary alpha Fornacis. The new invisible component is part of a 4-d short-period Ba-Bb subsystem, whose K-type alpha For Ba primary shows a striking [Ba/Fe] = +
