Hypervelocity intracluster stars ejected by supermassive black hole binaries
Kelly Holley-Bockelmann, Steinn Sigurdsson, J. Christopher Mihos +3
Hypervelocity stars have been recently discovered in the outskirts of galaxies, such as the unbound star in the Milky Way halo, or the three anomalously fast intracluster planetary…
Planetary Nebula Studies of Face-On Spiral Galaxies: Is the Disk Mass-to-Light Ratio Constant?
Kimberly A. Herrmann, Robin Ciardullo
When astronomers study the dark matter halos of spiral galaxies, they normally assume that the disk mass-to-light ratio is *constant*. We describe a method of analyzing the kinemat…
Close Binaries as the Progenitors of the Brightest Planetary Nebulae
Robin Ciardullo, Steinn Sigurdsson, John J. Feldmeier +1
We investigate the possible progenitors of the planetary nebulae (PNs) which populate the top 0.5 mag of the [O III] 5007 planetary nebula luminosity function (PNLF). We show that…
