SDSS J142625.71+575218.3: The First Pulsating White Dwarf with a Large Detectable Magnetic Field
P. Dufour, G. Fontaine, J. Liebert +2
We report the discovery of a strong magnetic field in the unique pulsating carbon-atmosphere white dwarf SDSS J142625.71+575218.3. From spectra gathered at the MMT and Keck telesco…
A Search for Binary Stars at Low Metallicity
David K. Lai, Sara Lucatello, Michael Bolte +2
We present initial results measuring the companion fraction of metal-poor stars ([Fe/H]2.0). We are employing the Lick Observatory planet-finding system to make high-precision…
Carbon and Strontium Abundances of Metal-Poor Stars
David K. Lai, Jennifer A. Johnson, Michael Bolte +1
We present carbon and strontium abundances for 100 metal-poor stars measured from R7000 spectra obtained with the Echellette Spectrograph and Imager at the Keck Observatory.…
Abundances of Extremely Metal-Poor Star Candidates
D. K. Lai, M. Bolte, J. A. Johnson +1
We present chemical abundances for 110 stars identified in objective-prism surveys as candidates to be very metal-poor. The abundances are derived from high S/N, intermediate-resol…
