The Primordial Binary Population - I: A near-infrared adaptive optics search for close visual companions to A star members of Scorpius OB2 [PDF]

, 2004
We present the results of a near-infrared adaptive optics survey with the aim to detect close companions to Hipparcos members in the three subgroups of the nearby OB association Sco OB2: Upper Scorpius (US), Upper Centaurus Lupus (UCL) and Lower ...

The rs10191329 Risk Allele Is Associated With Pronounced Retinal Layer Atrophy in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate whether the rs10191329 risk allele in the DYSF–ZNF638 locus, which is implicated in central nervous system resilience rather than immune‐mediated pathology, is associated with retinal layer thinning, a biomarker of neuroaxonal damage in relapsing multiple sclerosis (RMS). Methods From a prospective observational study,

Five New Sirius-like White Dwarf–Main-sequence Star Systems with MagAO-X

The Astronomical Journal
Most known white dwarfs in multiple systems with main-sequence stars have been discovered with M-type companions, because the white dwarf causes detectable UV excess and bluer colors than expected from a single M star.

Characteristics of Cerebral Palsy in the Midwestern US

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebral palsy (CP) is the most common lifelong motor disability worldwide. Yet, data is limited on how CP manifests in the US. Our objective was to characterize and determine factors affecting functional outcomes in a large population of young people with CP in the Midwestern US.

On the component masses of visual binaries [PDF]

Serbian Astronomical Journal, 2010
In the Sixth Catalog of Orbits of Visual Binary Stars we found those belonging to the Main Sequence to form a sample containing 432 visual binaries. Their total masses were obtained dynamically, i.e.

A Multiwavelength Classification and Study of Red Supergiant Candidates in NGC 6946

The Astrophysical Journal, 2023
We have combined resolved stellar photometry from Hubble Space Telescope (HST), Spitzer, and Gaia to identify red supergiant (RSG) candidates in NGC 6946, based on their colors, proper motions, visual morphologies, and spectral energy distributions.

An Interferometric and Spectroscopic Analysis of the Multiple Star System HD 193322

, 2011
The star HD 193322 is a remarkable multiple system of massive stars that lies at the heart of the cluster Collinder 419. Here we report on new spectroscopic observations and radial velocities of the narrow-lined component Ab1 that we use to determine its

Analysis of Soluble Interleukin‐2 Receptor as a Prognostic Biomarker in NMOSD and MOGAD

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Soluble interleukin‐2 receptor (sIL‐2R) is a biomarker for T cell activity. T cells are involved in neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) pathogenesis. However, sIL‐2R has so far not been evaluated in these conditions.
