A method of photometric data extraction for asteroids from time-domain surveys

Xiaoyun Xu, Xiaobing Wang, Karri Muinonen +9

The lightcurves of asteroids are essential for determining their physical characteristics, including shape, spin, size, and surface composition. However, most asteroids are missing…

Stellar cycle and evolution of polar spots in an M+WD binary

Xinlin Zhao, Song Wang, Xue Li +4

Stellar activity cycles reveal continuous relaxation and induction of magnetic fields. The activity cycle is typically traced through the observation of cyclic variations in total…

Magnetic activities on two single-lined RS Canum Venaticorum binaries IM Pegasi and Geminorum

Dongtao Cao, Shenghong Gu, F. Grundahl +1

We present the study on continuous high-resolution spectroscopic observations of two long-period single-lined RS Canum Venaticorum (RS CVn) binary stars IM Pegasi (IM Peg) and

Taxonomic analysis of asteroids with artificial neural networks

Nanping Luo, Xiaobin Wang, Shenghong Gu +3

We study the surface composition of asteroids with visible and/or infrared spectroscopy. For example, asteroid taxonomy is based on the spectral features or multiple color indices…

Magnetic topologies of two weak-line T Tauri stars TAP 4 and TAP 40

Yue Xiang, Shenghong Gu, J. -F. Donati +3

We present a Zeeman-Doppler imaging study of two weak-line T Tauri stars TAP 4 and TAP 40, based on the high-resolution spectropolarimetric observations with ESPaDOnS at the Canada…

Investigation of stellar magnetic activity using variational autoencoder based on low-resolution spectroscopic survey

Yue Xiang, Shenghong Gu, Dongtao Cao

We apply the variational autoencoder (VAE) to the LAMOST-K2 low-resolution spectra to detect the magnetic activity of the stars in the K2 field. After the training on the spectra o…
