    Sodium-Oxygen Anticorrelation and Neutron-capture Elements in Omega Centauri Stellar Populations
    Omega Centauri is no longer the only globular cluster known to contain multiple stellar populations, yet it remains the most puzzling. Due to the extreme way in...

    Solar Space Density of the Red Clump Stars and the Scale-Length of the Thin Disc
    We estimated the scale-length of the thin disc with the J and W1 magnitudes of the most probable red clump stars in the Galactic plane, - 0°.5 ⩽ b ⩽ +0°.5, in...
