Precise boron abundance in a sample of metal-poor stars from far-ultraviolet lines
Monique Spite, Beatriz Barbuy, Kefeng Tan
The light elements beryllium (Be; ) and boron (B; ) are mainly produced by spallation reactions between cosmic rays and carbon (C; ), nitrogen (N; ), and oxygen…
Looking for Signs of Unresolved Binarity in the Continuum of LAMOST Stellar Spectra
Mikhail Prokhorov, Kefeng Tan, Nikolay Samus +10
We describe an attempt to derive the binarity rate of samples of 166 A-, F-, G-, and K-type stars from LAMOST DR5 and 1000 randomly selected presumably single stars from Gaia DR3 c…
Unveiling the Variability and Chemical Composition of AL Col
Surath C. Ghosh, Santosh Joshi, Samrat Ghosh +9
Using \tess\ short-cadence (120\,s) SAP flux, we identified a rotational frequency of 0.09655\, (\,d). Wavelet analysis reveals that while…
Extraction of Physical Parameters of RRab Variables using Neural Network based Interpolator
Nitesh Kumar, Harinder P. Singh, Oleg Malkov +4
Determining the physical parameters of pulsating variable stars such as RR Lyrae is essential for understanding their internal structure, pulsation mechanisms, and evolutionary sta…
The Stellar Abundances and Galactic Evolution Survey (SAGES). II. Machine Learning-Based Stellar parameters for 21 million stars from the First Data Release
Hongrui Gu, Zhou Fan, Gang Zhao +14
Stellar parameters for large samples of stars play a crucial role in constraining the nature of stars and stellar populations in the Galaxy. An increasing number of medium-band pho…
