Direct N-Body Modeling of the Old Open Cluster NGC 188: A Detailed Comparison of Theoretical and Observed Binary Star and Blue Straggler Populations
Aaron M. Geller, Jarrod R. Hurley, Robert D. Mathieu
(Abridged) Following on from a recently completed radial-velocity survey of the old (7 Gyr) open cluster NGC 188 in which we study in detail the solar-type hard binaries and blue s…
A Search for OB Associations Near Southern Long-Period Cepheids. V. AQ Puppis and V620 Puppis
David G. Turner, Sidney van den Bergh, Frank Younger +3
A photometric UBV survey is presented for 610 stars in a region surrounding the Cepheid AQ Puppis and centered southwest of the variable, based upon photoelectric measures for 14 s…
Absolute Properties of the Triple Star CF Tauri
Claud H. Sandberg, Guillermo Torres, Antonio Claret
CF Tau is now known to be an eclipsing triple star with relatively deep total and annular eclipses. New light and radial velocity curves as well as new times of minima were obtaine…
Physical Properties of the B and Be Star Populations of h and chi Persei
Amber N. Marsh Boyer, M. Virginia McSwain, Christina Aragona +1
We present a study of the B and Be star populations of the Double Cluster h and chi Persei. Blue optical spectroscopy is used to first measure projected rotational velocity, V sin…
Testing Disk-Locking in NGC 2264
P. Wilson Cauley, Christopher M. Johns-Krull, Catrina M. Hamilton +1
We test analytic predictions from different models of magnetospheric accretion, which invoke disk-locking, using stellar and accretion parameters derived from models of low resolut…
The Inter-Eruption Timescale of Classical Novae from Expansion of the Z Camelopardalis Shell
Michael M. Shara, Trisha Mizusawa, David Zurek +3
The dwarf nova Z Camelopardalis is surrounded by the largest known classical nova shell. This shell demonstrates that at least some dwarf novae must have undergone classical nova e…
HST and Optical Data Reveal White Dwarf Cooling, Spin and Periodicities in GW Librae 3-4 Years after Outburst
Paula Szkody, Anjum S. Mukadam, Boris T. Gaensicke +9
Since the large amplitude 2007 outburst which heated its accreting, pulsating white dwarf, the dwarf nova system GW Librae has been cooling to its quiescent temperature. Our Hubble…
The Brown Dwarf Kinematics Project (BDKP). III. Parallaxes for 70 Ultracool Dwarfs
Jacqueline K. Faherty, Adam J. Burgasser, Frederick M. Walter +6
We report parallax measurements for 70 ultracool dwarfs (UCDs). Using both literature values and our sample, we report new polynomial relations between spectral type and M.…
Constraints on the Formation of the Galactic Bulge from Na, Al, and Heavy Element Abundances in Plaut's Field
Christian I. Johnson, R. Michael Rich, Chiaki Kobayashi +1
We report chemical abundances of Na, Al, Zr, La, Nd, and Eu for 39 red giant branch (RGB) stars and 23 potential inner disk red clump stars located in Plaut-s low extinction window…
