Half a Million Binary Stars Identified from the Low-resolution Spectra of LAMOST
The Astrophysical Journal Supplement SeriesBinary 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.

The BINSYN Program Package [PDF]
Journal of Astronomy and Space Sciences, 2012 The BINSYN program package, recently expanded to calculate synthetic spectra of cataclysmic variables, is being further extended to include synthetic photometry of ordinary binary stars in addition to binary stars with optically thick accretion disks ...

Application of Binary Evolution in Astrophysical Studies [PDF]
2011,ASPC,451,51, 2013 Binary stars evolve differently from single stars, thus binary evolution is very useful for astrophysical studies. This paper discusses the application of binary evolution in the studies of stars, star clusters, galaxies, and cosmology. In particular, I concentrate on the use of binary evolution in colour-magnitude diagram and spectral energy ...

Molecular Oncology, EarlyView.Microglia act as tumor suppressors during brain metastasis colonization but shift to a tumor‐promoting role after melanoma brain metastases form. NF‐κB/RelA signaling emerges as a key driver of this phenotypic shift. Targeting this pathway reprograms microglia into a pro‐inflammatory state, enhancing antitumor immunity and immune checkpoint inhibitor ...

Dynamics of Four Triple Systems
The Astronomical Journal, 2023 Orbital motions in four hierarchical stellar systems discovered by speckle interferometry are studied. Their inner orbits are relatively well constrained, while the long outer orbits are less certain.

Evolution of the binary population in young dense star clusters
, 2011 Context: Field stars are not always single stars, but can often be found in bound double systems. Since binary frequencies in the birth places of stars, young embedded clusters, are sometimes even higher than on average the question arises of how binary ...

On the formation of Be stars through binary interaction [PDF]
, 2014 Be stars are rapidly rotating B type stars. The origin of their rapid rotation is not certain, but binary interaction remains to be a possibility. In this work we investigate the formation of Be stars resulting from mass transfer in binaries in the Galaxy.

Tracing the Origins of Mass Segregation in M35: Evidence for Primordially Segregated Binaries
The Astrophysical Journal LettersM35 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 ...

The Effects of Binary Stars on the Color-Magnitude Diagrams of Young-Age Massive Star Clusters [PDF]
, 2018 Extended main-sequence turnoffs (eMSTO) have been observed in the color-magnitude diagram (CMD) of intermediate-age and young star clusters. The origin of the eMSTO phenomenon is still highly debated. Calculations show that the blue and faint (BF) stars in the CMD of NGC 1866 are hydrogen main sequence (MS) + naked He star systems.
