    • Projected Rotational Velocities for LAMOST Stars with Effective Temperatures Lower than 9000 K 

      Zuo, Fang; Luo, A-Li; Du, Bing; Li, Yinbi; Jones, Hugh R. A.; Song, Yi-han; Kong, Xiao; Guo, Yan-xin (2024-02-12)
      In Data Release 9 of LAMOST, we present measurements of v sin i for a total of 121,698 stars measured using the Medium Resolution Spectrograph (MRS) and 80,108 stars using the Low Resolution Spectrograph (LRS). These values ...

    • Stellar Atmospheric Parameters for Cool Dwarfs in Gaia Data Release 3 

      Qu, Cai-Xia; Luo, A-Li; Wang, Rui; Jones, Hugh R. A.; Du, Bing; Chen, Xiang-Lei; Wang, You-Fen (2024-02-01)
      We provide a catalog of atmospheric parameters for 1,806,921 cool dwarfs from Gaia Data Release 3 (DR3) that lie within the range covered by LAMOST cool dwarf spectroscopic parameters: 3200 K < T eff < 4300 K, −0.8 < [M/H] ...

    • Ultracool dwarfs identified using spectra in LAMOST DR7 

      Wang, You-Fen; Luo, A-Li; Chen, Wen-Ping; Jones, Hugh R. A.; Du, Bing; Li, Yin-Bi; Zhang, Shuo; Bai, Zhong-Rui; Kong, Xiao; Guo, Yan-Xin (2022-04-05)
      In this work, we identify 734 ultracool dwarfs with a spectral type of M6 or later, including one L0. Of this sample, 625 were studied spectroscopically for the first time. All of these ultracool dwarfs are within 360~pc, ...
