The Mount Wilson Observatory S-index of the Sun
Ricky Egeland, Willie Soon, Sallie Baliunas +3
The most commonly used index of stellar magnetic activity is the instrumental flux scale of singly-ionized calcium H & K line core emission, S, developed by the Mount Wilson Observ…
Dynamo Sensitivity in Solar Analogs with 50 Years of Ca II H & K Activity
Ricky Egeland, Willie Soon, Sallie Baliunas +3
The Sun has a steady 11-year cycle in magnetic activity most well-known by the rising and falling in the occurrence of dark sunspots on the solar disk in visible bandpasses. The 11…
Photospheric and chromospheric magnetic activity of seismic solar analogs. Observational inputs on the solar/stellar connection from Kepler and Hermes
D. Salabert, R. A. Garcia, P. G. Beck +8
We identify a set of 18 solar analogs among the seismic sample of solar-like stars observed by the Kepler satellite rotating between 10 and 40 days. This set is constructed using t…
Stellar Evidence that the Solar Dynamo may be in Transition
Travis S. Metcalfe, Ricky Egeland, Jennifer van Saders
Precise photometry from the Kepler space telescope allows not only the measurement of rotation in solar-type field stars, but also the determination of reliable masses and ages fro…
Magnetic variability in the young solar analog KIC 10644253: Observations from the Kepler satellite and the HERMES spectrograph
D. Salabert, C. Regulo, R. A. Garcia +12
The continuous photometric observations collected by the Kepler satellite over 4 years provide a whelm of data with an unequalled quantity and quality for the study of stellar evol…
