Early evolution of the Galactic halo revealed from Hipparcos observations of metal-poor stars
Masashi Chiba, Yuzuru Yoshii
The kinematics of 122 red giants and 124 RR Lyrae variables in the solar neighborhood is studied using accurate measurements of their proper motions by the Hipparcos astrometry sat…

Three-dimensional orbits of metal-poor halo stars and the formation of the Galaxy
Masashi Chiba, Yuzuru Yoshii
We present the three-dimensional orbital motions of metal-poor stars in conjunction with their metal abundances, for the purpose of getting insight into the formation process of th…

On The Origin Of Metallicity In Lyman-Alpha Forest Systems
Masashi Chiba, Biman B. Nath
We investigate the hypothesis that $\lyal$ absorption lines arise in two populations of halos --- minihalos of small circular velocity ($V_c \la 55$ km s) in which star form…
