An X-ray activity cycle on the young solar-like star
M. Coffaro, B. Stelzer, S. Orlando +7
In 2015 we started the XMM-Newton monitoring of the young solar-like star Epsilon Eridani (440 Myr), one of the youngest solar-like stars with a known chromospheric CaII cycle. By…
Evolution of Long Term Variability in Solar Analogs
Ricky Egeland, Willie Soon, Sallie Baliunas +2
Earth is the only planet known to harbor life, therefore we may speculate on how the nature of the Sun-Earth interaction is relevant to life on Earth, and how the behavior of other…
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…
Sun-Like Magnetic Cycles in the Rapidly-Rotating Young Solar Analog HD 30495
Ricky Egeland, Travis S. Metcalfe, Jeffrey C. Hall +1
A growing body of evidence suggests that multiple dynamo mechanisms can drive magnetic variability on different timescales, not only in the Sun but also in other stars. Many solar…
Characterization of Potential U.S. Sites for the Cherenkov Telescope Array
R. A. Ong, T. Aune, J. Hall
The Cherenkov Telescope Array (CTA) is a major ground-based observatory proposed for gamma-ray astronomy. CTA is envisioned to consist of two large arrays of atmospheric Cherenkov…
