Query: High Resolution Spectroscopy and Spectropolarimetry of some late
  F-/early G-type sun-like stars as targets for Zeeman Doppler imaging   High resolution spectroscopy and spectropolarimetry have been undertaken at
the Anglo-Australian Telescope in order to identify suitable targets for
magnetic studies of young sun-like stars, for the proxy study of early solar
evolution. This study involved the investigation of some variable late F-/early
G-type sun-like stars originally identified by the Hipparcos mission. Of the 38
stars observed for this study, HIP 31021, HIP 64732, HIP 73780 were found to be
spectroscopic binary stars while HIP 19072, HIP 67651 and HIP 75636 are also
likely to be binaries while HIP 33111 could even be a triple system. Magnetic
fields were detected on a number of the survey stars: HIP 21632, HIP 43720, HIP
48770, HIP 62517, HIP 71933, HIP 77144, HIP 89829, HIP 90899 and HIP 105388,
making these stars good candidates for follow-up Zeeman Doppler imaging
studies.
