Half a Million Binary Stars Identified from the Low-resolution Spectra of LAMOST

open access: yesThe Astrophysical Journal Supplement Series
Binary stars are prevalent yet challenging to detect. We present a novel approach using convolutional neural networks (CNNs) to identify binary stars from low-resolution spectra obtained by the LAMOST survey.

Tracing the Origins of Mass Segregation in M35: Evidence for Primordially Segregated Binaries

open access: yesThe Astrophysical Journal Letters
M35 is a young open cluster and home to an extensive binary population. Using Gaia Data Release 3, Pan-STARRS, and Two Micron All Sky Survey photometry with the Bayesian statistical software, BASE-9, we derive precise cluster parameters, identify single ...

TESS Light Curve of the Interacting Binary W Serpentis

open access: yesThe Astronomical Journal
The unusal light curve of the massive eclipsing binary W Ser was recently observed with high S/N and fast cadence by the NASA TESS mission. The TESS light curve records two eclipses and relatively fast variations outside of the eclipses.

Gaia’s binary star renaissance

open access: yesNew Astronomy Reviews
Stellar multiplicity is among the oldest and richest problems in astrophysics. Binary stars are a cornerstone of stellar mass and radius measurements that underpin modern stellar evolutionary models. Binaries are the progenitors of many of the most interesting and exotic astrophysical phenomena, ranging from type Ia supernovae to gamma ray bursts ...

Mass Transfer in Eccentric Orbits with Self-consistent Stellar Evolution

open access: yesThe 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.

The Pleiades Binary Fraction Revisited

open access: yesThe Astronomical Journal
One of the nearest and best-studied open clusters, the Pleiades is an important cornerstone of stellar astrophysics. Despite its role as a reference coeval stellar population, its multiplicity properties are still not well characterized. The combined use
