Abstract:
We have determined spectroscopic orbits for five single-lined
spectroscopic binaries, HD100167, HD135991, HD140667, HD158222,
HD217924. Their periods range from 60.6 to 2403days and the
eccentricities from 0.20 to 0.84. Our spectral classes for the stars
confirm that they are of solar type, F9-G5, and all are dwarfs. Their
[Fe/H] abundances, determined spectroscopically, are close to the
solar value and on average are 0.12 greater than abundances from a
photometric calibration. Four of the five stars are rotating faster
than their predicted pseudosynchronous rotational velocities.
Description:
From 2002 through 2012 we obtained observations at the Kitt Peak
National Observatory (KPNO) with the coude feed telescope and coude
spectrograph. The vast majority were acquired with a TI CCD detector,
and those spectrograms were centered at 6430Å, cover a wavelength
range of 84Å, and have a resolution of 0.21Å or a resolving
power of just over 30000. The TI CCD was unavailable in 2008
September, and so a Tektronics CCD, designated T1KA, was used instead.
With that CCD the spectrum was centered at 6400Å. Although the
wavelength range covered by the chip increased to 172Å, the
resolving power decreased to 19000. Beginning in 2010 September we
acquired spectra with a CCD, consisting of a 2600*4000 array of
12µm pixels, that was made by Semiconductor Technology Associates
and designated STA2. With STA2 the spectrum was once again centered at
6430Å, and the much larger size of the detector produced a
wavelength range of 336Å. The spectrograph slit was set so that the
STA2 spectra have the same resolution as those acquired with the TI
CCD although there is some worsening of the resolution at both ends of
the STA2 spectra. All our KPNO spectra have signal-to-noise (S/N)
ratios of about 150.
Starting in 2006, we collected additional spectrograms with the
Tennessee State University (TSU) 2m automatic spectroscopic telescope
(AST) and a fiber-fed echelle spectrograph, situated at Fairborn
Observatory near Washington Camp in the Patagonia Mountains of
southeastern Arizona. Through 2011 June the detector was a 2048*4096
SITe ST-002A CCD with 15µm pixels. The AST echelle spectrograms
have 21 orders that cover the wavelength range 4920-7100Å, and most
have an average resolution of 0.17Å although a few have a slightly
lower resolution of 0.24Å. The S/N ratios ranged from 30 to 80.
