Spectral classification of B stars: The empirical sequence using SDSS-IV/APOGEE near-IR data

Valeria G. Ramírez-Preciado, Alexandre Román-Lópes, Carlos G. Román-Zuñiga +5

We present a semi-empirical spectral classification scheme for normal B-type stars using near-infrared spectra (1.5-1.7 $μ$ m) from the SDSS APOGEE2-N DR14 database. The main motiva…

Kinematic identification of young nearby moving groups from a sample of chromospherically active stars in the RAVE catalog

Valeria Ramírez-Preciado, Carlos G. Roman-Zuñiga, Luis Aguilar +2

The purpose of this study is the identification of young ( $1 < a g e < 100$ Myr), nearby ( $d ⩽ 100$ pc) moving groups (YNMGs) through their kinematic signature. YNMGs could be…
