Nuclear Masses in Astrophysics
Christine Weber, Klaus Blaum, Hendrik Schatz
Among all nuclear ground-state properties, atomic masses are highly specific for each particular combination of N and Z and the data obtained apply to a variety of physics topics.…
On The Origin Of The Highest Redshift Gamma-Ray Bursts
Krzysztof Belczynski, Daniel E. Holz, Chris L. Fryer +3
GRB 080913 and GRB 090423 are the most distant gamma-ray bursts (GRBs) known to-date, with spectroscopically determined redshifts of z=6.7 and z=8.1, respectively. The detection of…
The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
Orion's Bar: Physical Conditions across the Definitive H+ / H0 / H2 Interface
E. W. Pellegrini, J. A. Baldwin, G. J. Ferland +2
Previous work has shown the Orion Bar to be an interface between ionized and molecular gas, viewed roughly edge on, which is excited by the light from the Trapezium cluster. Much o…
Color Bimodality in M87 Globular Clusters
Christopher Z. Waters, Stephen E. Zepf, Tod R. Lauer +1
We present an analysis of a 50 orbit HST ACS observation of the M87 globular cluster system. We use the extraordinary depth of this dataset to test whether the colors and magnitude…
WFCAM Survey of M31 Globular Clusters: Low Mass X-ray Binaries
Mark B. Peacock, Thomas J. Maccarone, Christopher Z. Waters +4
We investigate the relationship between Low Mass X-ray Binaries (LMXBs) and globular clusters (GCs) using UKIRT observations of M31 and existing Chandra, XMM-Newton, and ROSAT cata…
Chandra and Swift observations of the quasi-persistent neutron star transient EXO 0748-676 back to quiescence
N. Degenaar, R. Wijnands, M. T. Wolff +8
The quasi-persistent neutron star X-ray transient and eclipsing binary EXO 0748-676 recently started the transition to quiescence following an accretion outburst that lasted more t…
An extensive photometric study of the Blazhko RR Lyrae star MW Lyr: II. Changes in the physical parameters
J. Jurcsik, Á. Sódor, B. Szeidl +11
The analysis of the multicolour photometric observations of MW Lyr, a large modulation amplitude Blazhko variable, shows for the first time how the mean global physical parameters…
Old-Population Hypervelocity Stars from the Galactic Center: Limits from the SDSS
Juna A. Kollmeier, Andrew Gould, Gillian Knapp +1
We present limits on the ejection of old-population HVS from a sample of over 290,000 stars selected from the SDSS. We derive the speed at the solar circle from the measured positi…
Comparison of statistical treatments for the equation of state for core-collapse supernovae
S. R. Souza, A. W. Steiner, W. G. Lynch +2
Neutrinos emitted during the collapse, bounce and subsequent explosion provide information about supernova dynamics. The neutrino spectra are determined by weak interactions with n…
The Globular Cluster NGC 5286. I. A New CCD BV Color-Magnitude Diagram
M. Zorotovic, M. Catelan, M. Zoccali +5
We present BV photometry of the Galactic globular cluster NGC 5286, based on 128 V frames and 133 B frames, and covering the entire face of the cluster. Our photometry reaches almo…
Beryllium Abundances in Stars of One-Solar-Mass
Ann Merchant Boesgaard, Julie A. Krugler
We have determined Be abundances in 50 F and G dwarfs in the mass range of 0.9 M 1.1 as determined by Lambert & Reddy. The effective temperatures are 5600 to…
Carbon Abundances of Three Carbon-Enhanced Metal-Poor Stars from High-Resolution Gemini-S/bHROS Spectra of the 8727A [C I] Line
S. C. Schuler, S. J. Margheim, T. Sivarani +4
We present the results from an analysis of the 8727ang forbidden [C I] line in high-resolution Gemini-S/bHROS spectra of three CEMP stars. We find the [C/Fe] ratios based on the [C…
The stellar content of the Hamburg/ESO survey. V. The metallicity distribution function of the Galactic halo
T. Schoerck, N. Christlieb, J. G. Cohen +22
We determine the metallicity distribution function (MDF) of the Galactic halo by means of a sample of 1638 metal-poor stars selected from the Hamburg/ESO objective-prism survey (HE…
Dependence of S-Process Nucleosynthesis in Massive Stars on Triple-Alpha and 12C(a,g)16O Reaction Rate Uncertainties
Clarisse Tur, Alexander Heger, Sam M. Austin
We have studied the sensitivity of s-process nucleosynthesis in massive stars to +/- 2 sigma variations in the rates of the triple alpha and 12C(a,g)16O reactions. We simulated the…
A Bitter Pill: The Primordial Lithium Problem Worsens
Richard H. Cyburt, Brian D. Fields, Keith A. Olive
The lithium problem arises from the significant discrepancy between the primordial 7Li abundance as predicted by BBN theory and the WMAP baryon density, and the pre-Galactic lithiu…
The Variable Stars of the Draco Dwarf Spheroidal Galaxy - Revisited
K. Kinemuchi, H. C. Harris, Horace A. Smith +4
We present a CCD survey of variable stars in the Draco dwarf spheroidal galaxy. This survey, which has the largest areal coverage since the original variable star survey by Baade &…
Proton-Rich Nuclear Statistical Equilibrium
I. R. Seitenzahl, F. X. Timmes, A. Marin-Laflèche +3
Proton-rich material in a state of nuclear statistical equilibrium (NSE) is one of the least studied regimes of nucleosynthesis. One reason for this is that after hydrogen burning,…
