Eclipse Depth Variations in Seven Eclipsing Binaries as Observed by KELT and TESS
The Astronomical JournalA set of eclipsing binary systems exhibit a changing inclination over time due to the gravitational influence of a third stellar companion. These changing inclinations manifest in photometric observations over time as eclipse depth variations.

Evolution of binary stars in multiple-population globular clusters [PDF]
, 2015 The discovery of multiple stellar populations in globular clusters has implications for all the aspects of the study of these stellar systems. In this paper, by means of N-body simulations, we study the evolution of binary stars in multiple-population ...

Wolf-Rayet stars in the Small Magellanic Cloud as testbed for massive star evolution
, 2018 The majority of Wolf-Rayet (WR) stars represent the stripped cores of evolved massive stars who lost most of their hydrogen envelope. In low metallicity environments, such as the Small Magellanic Cloud (SMC), stellar winds are weaker and binary ...

Genetic Modifiers of Parkinson's Disease: A Case–Control Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To examine the associations of LRRK2 p.G2019S, GBA1 p.N409S, polygenic risk scores (PRS), and APOE E4 on PD penetrance, risk, and symptoms. Methods We conducted a US‐based observational case–control study using data from the 23andMe Inc. and Fox Insight Genetic Substudy (FIGS) databases.

Contact-binary Evolution with Energy Transfer and Saturated Magnetic Braking
The Astrophysical JournalThe evolution of low-mass contact binaries is influenced by angular momentum loss, mass and energy transfer (ET), and the nuclear evolution of the components.

Binary central stars of planetary nebulae [PDF]
, 2006 This paper reviews our knowledge on binary central stars of planetary nebulae and presents some personal opinions regarding their evolution. Three types of interactions are distinguished: type I, where the binary companion induces the mass loss; type II,

The Frequency of Binary Stars in the Core of 47 Tucanae
, 2001 Differential time series photometry has been derived for 46422 main-sequence stars in the core of 47 Tucanae. The observations consisted of near-continuous 160-s exposures alternating between the F555W and F814W filters for 8.3 days in 1999 July with ...

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.

Stellar Properties of Observed Stars Stripped in Binaries in the Magellanic Clouds
The Astrophysical Journal, 2023 Massive stars (∼8–25 M _⊙ ) stripped of their hydrogen-rich envelopes via binary interaction are thought to be the main progenitors for merging neutron stars and stripped-envelope supernovae.
