Design and optimization of dihedral angle offsets for the next generation lunar retro-reflectors
C. Wu, D. Currie, D. Wellnitz +1
Lunar laser ranging (LLR) to the Apollo retro-reflectors, which features the most long-lasting experiment in testing General Relativity theories, has remained operational over the…
Stellar Astrophysics with a Dispersed Fourier Transform Spectrograph. II. Orbits of Double-lined Spectroscopic Binaries
Bradford B. Behr, Andrew T. Cenko, Arsen R. Hajian +4
We present orbital parameters for six double-lined spectroscopic binaries (iota Pegasi, omega Draconis, 12 Bootis, V1143 Cygni, beta Aurigae, and Mizar A) and two double-lined trip…
Vertical stratification of iron in atmospheres of blue horizontal-branch stars
V. Khalack, F. LeBlanc, B. B. Behr
The aim of this study is to search for observational evidence of vertical iron stratification in the atmosphere of fourteen blue horizontal-branch (BHB) stars. We have found from o…
Stellar Astrophysics with a Dispersed Fourier Transform Spectrograph. I. Instrument Description and Orbits of Single-lined Spectroscopic Binaries
Bradford B. Behr, Arsen R. Hajian, Andrew T. Cenko +4
We have designed and constructed a second-generation version of the Dispersed Fourier Transform Spectrograph, or dFTS. This instrument combines a spectral interferometer with a dis…
Vertical stratification of iron abundance in atmospheres of blue horizontal-branch stars
V. Khalack, F. LeBlanc, B. B. Behr +2
The observed slow rotation and abundance peculiarities of certain blue horizontal branch (BHB) stars suggests that atomic diffusion can be important in their stellar atmospheres an…
Search for vertical stratification of metals in atmospheres of blue horizontal-branch stars
V. R. Khalack, F. LeBlanc, B. B. Behr +2
The observed abundance peculiarities of many chemical species relative to the expected cluster metallicity in blue horizontal-branch (BHB) stars presumably appear as a result of at…
