Stellar Activity Cycles
Sandra V. Jeffers, Rene Kiefer, Travis S. Metcalfe
The magnetic field of the Sun is generated by internal dynamo process with a cyclic period of 11 years or a 22 year magnetic cycle. The signatures of the Sun's magnetic cycle are o…
Stellar Cruise Control: Weakened Magnetic Braking Leads to Sustained Rapid Rotation of Old Stars
Nicholas Saunders, Jennifer L. van Saders, Alexander J. Lyttle +8
Despite a growing sample of precisely measured stellar rotation periods and ages, the strength of magnetic braking and the degree of departure from standard (Skumanich-like) spindo…
Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis
Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31
The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…
Overview and Validation of the Asteroseismic Modeling Portal v2.0
Travis S. Metcalfe, Richard H. D. Townsend, Warrick H. Ball
The launch of NASA's Kepler space telescope in 2009 revolutionized the quality and quantity of observational data available for asteroseismic analysis. While Kepler was able to det…
Asteroseismology with the Roman Galactic Bulge Time-Domain Survey
Daniel Huber, Marc Pinsonneault, Paul Beck +24
Asteroseismology has transformed stellar astrophysics. Red giant asteroseismology is a prime example, with oscillation periods and amplitudes that are readily detectable with time-…
Constraints on Magnetic Braking from the G8 Dwarf Stars 61 UMa and Cet
Travis S. Metcalfe, Klaus G. Strassmeier, Ilya V. Ilyin +11
During the first half of their main-sequence lifetimes, stars rapidly lose angular momentum to their magnetized winds, a process known as magnetic braking. Recent observations sugg…
