Observations of binary stars with the differential speckle survey instrument. IV. Observations of Kepler, CoRoT, and Hipparcos stars from the Gemini North Telescope

, 2012
We present the results of 71 speckle observations of binary and unresolved stars, most of which were observed with the DSSI speckle camera at the Gemini North Telescope in 2012 July. The main purpose of the run was to obtain diffraction-limited images of

Clinical and Modifiable Factors Associated With Disability and Relapse in MOGAD: A Multicentre Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Factors associated with relapse course and disability in myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) remain incompletely understood. Objectives To identify clinical and modifiable factors associated with relapse and disability in MOGAD. Methods In this ambispective multicentre cohort study using data from

Mass Transfer in Eccentric Orbits with Self-consistent Stellar Evolution

The Astrophysical Journal
We investigate Roche lobe overflow mass transfer (MT) in eccentric binary systems between stars and compact objects (COs), modeling the coupled evolution of both the star and the orbit due to eccentric MT (eMT) in a self-consistent framework.

UV Observations of Close Binary Stars [PDF]

Highlights of Astronomy, 1983
Ultraviolet spectroscopic observations made with the Copernicus and IUE spacecraft have been analyzed. The observations represent a collaborative effort with G. J. Peters.Observational evidence supporting the existence of a turbulent accretion layer has been discussed earlier by Peters. Ionization equilibrium calculations suggest the following physical

Quantitative MRI Uncovers Subtle Cortical Damage in Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether myelin‐sensitive quantitative MRI reveals microstructural abnormalities in normal‐appearing cortex (NACtx) in myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), indicating that conventional MRI underestimates remission residual cortical injury.

Detached Post-Algol Eclipsing Binaries Caught between Case A and Case AB Mass Transfer

The Astrophysical Journal
For 60 yr, stellar evolutionary models have predicted that intermediate-mass stars slightly contract on the terminal-age main sequence (TAMS) as they exhaust hydrogen in their convective cores, producing the main-sequence (MS) hook on the Hertzsprung ...

BLACK HOLE X-RAY BINARIES

Odessa Astronomical Publications, 2017
Masses of black holes in 13 X-ray binary systems determined by different authors are summarized and compared with those of WR stars in close binary systems, which can be considered as progenitors of relativistic objects.

The Evolution of Close Binaries and the Am Stars [PDF]

Highlights of Astronomy, 1968
In this paper, I shall be concerned with three related questions: (a) what is the evolutionary fate of close binary systems, (b) is this concept consistent with the number of evolved close binary systems, and (c) are these evolved systems the Am stars?

Deep Learning Pose Estimation for Phenotyping of Co‐Occurring Hyperkinetic Movement Disorders

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore whether routine outpatient video combined with deep learning‐based pose estimation and clinically interpretable kinematic features can support multi‐label phenotyping of co‐occurring hyperkinetic movement disorders (HMDs).

Eclipsing Millisecond Pulsars with He Star Companions

The Astrophysical Journal
Eclipsing millisecond pulsars (MSPs) are a type of pulsar binaries with close orbits (≲1.0 day). They are important objects for studying the accretion history of neutron stars (NSs), pulsar winds, and the origin of isolated MSPs, etc.
