Abstract:
We have obtained spectroscopy and photometry of three chromospherically
active, single-lined spectroscopic binaries: HD 37824 (V1149 Ori), HD
181809 (V4138 Sgr), and HD 217188 (AZ Psc).
* HD 37824 has a circular orbit with a period of 53.57 days. Its primary
is a K0 III star, while the secondary is likely a G or K dwarf.
* HD 181809 has an orbit with a period of 13.04667 days and a low
eccentricity of 0.040. The primary has a spectral type of K0 IIIIV,
and its secondary is probably an M dwarf.
* The orbit of HD 217188 has a period of 47.1209 days and a moderately
high eccentricity of 0.470. The spectral type of the primary is K0III,
while the secondary is likely an M dwarf.
All three systems are estimated to have near solar iron abundances.
Photometric observations spanning 15-16 years for all three stars
yield mean photometric periods of 53.12, 59.85, and 90.89 days for HD
37824, HD 181809, and HD 217188, respectively.
