Hamilton Echelle Spectrograph Observations of Solar Analog Field Stars: Lithium Abundance and Activity
We measured lithium (Li) abundance and instantaneous chromospheric Ca ii HK activity in Hamilton Echelle Spectrograph observations of 211 solar analog field stars, with one objective being potential identification of grand minimum candidates for ongoing multiyear observation. At the zero-age main se...
