Searching for Black Hole Candidates by LAMOST and ASAS-SN
Ling-Lin Zheng, Wei-Min Gu, Tuan Yi +13
Most dynamically confirmed stellar-mass black holes and the candidates were originally selected from X-ray outbursts. In the present work, we search for black hole candidates in th…
Properties of Radial Velocities measurement based on LAMOST-II Medium-Resolution Spectroscopic Observations
R. Wang, A. -L. Luo, J. -J. Chen +28
The radial velocity (RV) is a basic physical quantity which can be determined through Doppler shift of the spectrum of a star. The precision of RV measurement depends on the resolu…
Machine Learning Regression of stellar effective temperatures in the second Data Release
Yu Bai, JiFeng Liu, ZhongRui Bai +2
This paper reports on the application of the supervised machine-learning algorithm to the stellar effective temperature regression for the second data release, based on the…
A Method to Search for Black Hole Candidates with Giant Companions by LAMOST
Wei-Min Gu, Hui-Jun Mu, Jin-Bo Fu +10
We propose a method to search for stellar-mass black hole (BH) candidates with giant companions from spectroscopic observations. Based on the stellar spectra of LAMOST Data Release…
X-ray Activity from Different Types of Stars
Lin He, Song Wang, Xiaojie Xu +10
X-ray emission is an important indicator of stellar activity. In this paper, we study stellar X-ray activity using the XMM-Newton and LAMOST data for different types of stars. We p…
Radial velocity measurements from LAMOST medium-resolution spectroscopic observations: A pointing towards the Kepler field
Nian Liu, Jian-Ning Fu, Weikai Zong +20
Radial velocity is one of key measurements in understanding the fundamental properties of stars, stellar clusters and the Galaxy. A plate of stars in the Kepler field were observed…
