Deciphering Solar Magnetic Activity: 140 Years Of The `Extended Solar Cycle' -- Mapping the Hale Cycle

Scott W. McIntosh, Robert J. Leamon, Ricky Egeland +6

We investigate the occurrence of the "extended solar cycle" (ESC) as it occurs in a host observational data spanning 140 years. Investigating coronal, chromospheric, photospheric a…

The Evolution of Rotation and Magnetic Activity in 94 Aqr Aa from Asteroseismology with TESS

Travis S. Metcalfe, Jennifer L. van Saders, Sarbani Basu +29

Most previous efforts to calibrate how rotation and magnetic activity depend on stellar age and mass have relied on observations of clusters, where isochrones from stellar evolutio…

Overlapping Magnetic Activity Cycles and the Sunspot Number: Forecasting Sunspot Cycle 25 Amplitude

Scott W. McIntosh, Sandra C. Chapman, Robert J. Leamon +2

The Sun exhibits a well-observed modulation in the number of spots on its disk over a period of about 11 years. From the dawn of modern observational astronomy sunspots have presen…

Sun-like Stars Shed Light on Solar Climate Forcing

P. G. Judge, R. Egeland, G. W. Henry

Recently published, precise stellar photometry of 72 Sun-like stars obtained at the Fairborn Observatory between 1993 and 2017 is used to set limits on the solar forcing of Earth's…

Age dating of an early Milky Way merger via asteroseismology of the naked-eye star Indi

William J. Chaplin, Aldo M. Serenelli, Andrea Miglio +81

Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies. While these accreted stellar populations can be forensically identified as kinematic…
