cds-question@unistra.frthe-sung-starsphotometryWe present 14 years of contemporaneous photometric and spectroscopic observations of 28 solar analog stars, taken with the Tennessee State University Automatic Photometric Telescopes at Fairborn Observatory and the Solar-Stellar Spectrograph at Lowell Observatory. These are the best observed and most nearly Sun-like of the targets in our magnitude-limited (V<=7.5) sample. The correlations between luminosity and activity reveal the expected inverse activity-brightness correlations for active stars. Strong direct correlations between activity and brightness are not prevalent for the less active solar age stars, but are precision limited.2009AJ....138..312Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/138/312CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/468/663 : Li abundances in solar-analog stars (Takeda+, 2007)J/A+A/508/L17 : Abundances in solar analogs (Ramirez+, 2009)J/ApJS/181/62 : Survey of young solar analogs (Metchev+, 2009)J/A+A/515/A93 : Li abundances in solar-analog stars.
