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

The 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.
