LBT/PEPSI Spectropolarimetry of a Magnetic Morphology Shift in Old Solar-type Stars
Travis S. Metcalfe, Oleg Kochukhov, Ilya V. Ilyin +3
Solar-type stars are born with relatively rapid rotation and strong magnetic fields. Through a process known as magnetic braking, the rotation slows over time as stellar winds grad…
Magnetic activity of the solar-like star HD 140538
M. Mittag, J. H. M. M. Schmitt, T. S. Metcalfe +2
The periods of rotation and activity cycles are among the most important properties of the magnetic dynamo thought to be operating in late-type, main-sequence stars. In this paper,…
Sounding stellar cycles with Kepler - III. Comparative analysis of chromospheric, photometric and asteroseismic variability
C. Karoff, T. S. Metcalfe, B. T. Montet +4
By combining ground-based spectrographic observations of variability in the chromospheric emission from Sun-like stars with the variability seen in their eigenmode frequencies, it…
