On the Determination of Stellar Mass and Binary Fraction of Open Clusters within 500 pc from the Sun

Yueyue Jiang, Jing Zhong, Songmei Qin +3

We investigated the stellar mass function and the binary fraction of 114 nearby open clusters (OCs) using the high-precision photometric data from Gaia Data Release 3 (Gaia DR3). W…

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…
