An Analysis of the Broadband (22-3900 MHz) Radio Spectrum of HB3 (G132.7+1.3): The Detection of Thermal Radio Emission from an Evolved Supernova Remnant?
D. Urosevic, T. Pannuti, D. Leahy
We present an analysis of the broadband radio spectrum (from 22 to 3900 MHz) of the Galactic supernova remnant (SNR) HB3 (G132.7+1.3). Published observations have revealed that a c…
A Comparison Between the Globular Clusters in NGC 5128 and the Galaxy
Sidney van den Bergh
Some of the properties of the globular clusters in NGC 5128 are compared to those of Galactic globular clusters. Assuming the color- metallicity relations that hold for Galactic gl…
The HgMn Binary Star Phi Herculis: Detection and Properties of the Secondary and Revision of the Elemental Abundances of the Primary
R. T. Zavala, S. J. Adelman, C. A. Hummel +6
Observations of the Mercury-Manganese star Phi Herculis with the Navy Prototype Optical Interferometer (NPOI) conclusively reveal the previously unseen companion in this single-lin…
Deep HST Photometry of NGC 6388: Age and Horizontal Branch Luminosity
M. Catelan, P. B. Stetson, B. J. Pritzl +5
Using the Hubble Space Telescope, we have obtained the first color-magnitude diagram (CMD) to reach the main-sequence turnoff of the Galactic globular cluster NGC 6388. From a comp…
MOST Detects g-Modes in the Late-Type be Star beta CMi (B8Ve)
H. Saio, C. Cameron, R. Kuschnig +10
The Microvariability and Oscillations of stars (MOST) satellite has detected low-amplitude light variations (1 mmag) in the Be star CMi (B8Ve). The observations lasted…
A Search for Nitrogen-Enhanced Metal-Poor Stars
Jennifer A. Johnson, Falk Herwig, Timothy C. Beers +1
Theoretical models of very metal-poor intermediate-mass Asymptotic Giant Branch (AGB) stars predict a large overabundance of primary nitrogen. The very metal-poor, carbon-enhanced,…
