When Do Planets Form? A Search for Extra-solar Planets Around Metal-Poor Stars
A. Sozzetti, D. W. Latham, G. Torres +4
We present preliminary results from our spectroscopic search for planets within 1 AU of metal-poor field dwarfs using NASA time with HIRES on Keck I. The core accretion model of ga…

Properties of QSO Metal Line Absorption Systems at High Redshifts: Nature and Evolution of the Absorbers and the Ionizing Radiation Background
Alec Boksenberg, Wallace L. W. Sargent, Michael Rauch
In Keck HIRES spectra of 9 QSOs we identify a sample of 908 CIV absorber components in 188 systems outside the Lyman forest in the redshift range 1.6 < z < 4.4, with related lines…
