The Runaway White Dwarf LP400-22 Has a Companion
Mukremin Kilic, Warren R. Brown, Carlos Allende Prieto +4
We report the detection of a radial velocity companion to the extremely low mass white dwarf LP400-22. The radial velocity of the white dwarf shows variations with a semi-amplitude…
The Anisotropic Spatial Distribution of Hypervelocity Stars
Warren R. Brown, Margaret J. Geller, Scott J. Kenyon +1
We study the distribution of angular positions and angular separations of unbound hypervelocity stars (HVSs). HVSs are spatially anisotropic at the 3-sigma level. The spatial aniso…
Hypervelocity Stars: From the Galactic Center to the Halo
S. J. Kenyon, B. C. Bromley, M. J. Geller +1
Hypervelocity stars (HVS) traverse the Galaxy from the central black hole to the outer halo. We show that the Galactic potential within 200 pc acts as a high pass filter preventing…
The Century Survey Galactic Halo Project III: A Complete 4300 deg^2 Survey of Blue Horizontal Branch Stars in the Metal-Weak Thick Disk and Inner Halo
Warren R. Brown, Timothy C. Beers, Ronald Wilhelm +4
We present a complete spectroscopic survey of 2414 2MASS-selected blue horizontal branch (BHB) candidates selected over 4300 deg^2 of the sky. We identify 655 BHB stars in this non…
Hypervelocity Stars III. The Space Density and Ejection History of Main Sequence Stars from the Galactic Center
Warren R. Brown, Margaret J. Geller, Scott J. Kenyon +2
We report the discovery of 3 new unbound hypervelocity stars (HVSs), stars traveling with such extreme velocities that dynamical ejection from a massive black hole (MBH) is their o…
The Discovery of a Companion to the Lowest Mass White Dwarf
Mukremin Kilic, Warren R. Brown, Carlos Allende Prieto +2
We report the detection of a radial velocity companion to SDSS J091709.55+463821.8, the lowest mass white dwarf currently known with M~0.17Msun. The radial velocity of the white dw…
