Are There Unstable Planetary Systems around White Dwarfs
The presence of planets around solar-type stars suggests that many white dwarfs should have relic planetary systems. While planets closer than ~5 AU will most likely not survive theExpand

Closing in on a Short-Hard Burst Progenitor: Constraints from Early-Time Optical Imaging and Spectroscopy of a Possible Host Galaxy of GRB 050509b
The localization of the short-duration, hard-spectrum gamma-ray burst GRB 050509b by the Swift satellite was a watershed event. We report the discovery of the probable host galaxy, a brightExpand

A Young White Dwarf Companion to Pulsar B1620-26: Evidence for Early Planet Formation
The pulsar B1620-26 has two companions, one of stellar mass and one of planetary mass. We detected the stellar companion with the use of Hubble Space Telescope observations. The color and magnitudeExpand

The binary star population of the young cluster NGC 1818 in the Large Magellanic Cloud
We determine the binary star fraction as a function of radius in NGC 1818, a young rich cluster in the Large Magellanic Cloud, using Hubble Space Telescope images in bands F336W (∼U) and F555W (∼V).Expand

Binary-single star interactions in globular clusters
An extensive series of three-body interactions involving hard binaries and single stars are calculated by direct integration of ∼10 5 encounters. Unlike previous calculations, the stars haveExpand

Measuring mass-loss rates from Galactic satellites
Number count profiles of many Galactic and some extra-galactic satellite systems show evidence for associated stars beyond the cut-off in density that is identified as the point of tidal limitationExpand

The Metallicity Distribution of Intracluster Stars in Virgo
We have used the Hubble Space Telescope's Advanced Camera for Surveys (ACS) to detect and measure ~5300 stars in a single intracluster field in the Virgo Cluster. Expand

Models of Galaxies with Central Black Holes: Adiabatic Growth in Spherical Galaxies
We add black holes to nonrotating, spherical galaxy models, with the assumption that the black-hole growth is slow compared with the dynamical time but fast compared with the relaxation time. TheExpand

Close Binaries as the Progenitors of the Brightest Planetary Nebulae
We investigate the possible progenitors of the planetary nebulae (PNs) that populate the top 0.5 mag of the [O III] λ5007 planetary nebula luminosity function (PNLF). We show that the absoluteExpand
