Extending asteroseismic magnetometry across the diverse landscape of magnetic structures
Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +5
Magnetic fields have now been asteroseismically measured in the cores of many red giants. However, most interpretations of these measurements assume that the magnetic field is far…
Asteroseismic imprints of strong non-axisymmetric fields in the cores of red giants
Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +5
To date, magnetic fields have been asteroseismically measured in nearly one hundred red giant cores. However, most analyses assume weak magnetic fields and slow rotation so that pe…
Unified Kraft Break at ~6500 K: A Newly Identified Single-Star Obliquity Transition Matches the Classical Rotation Break
Xian-Yu Wang, Songhu Wang, J. M. Joel Ong
The stellar obliquity transition, defined by a cut separating aligned from misaligned hot Jupiter systems, has long been assumed to coincide with the rotatio…
TESS asteroseismology of Hydri: a subgiant with a born-again dynamo
Travis S. Metcalfe, Jennifer L. van Saders, Daniel Huber +12
The solar-type subgiant Hyi has long been studied as an old analog of the Sun. Although the rotation period has never been measured directly, it was estimated to be near 27 day…
Stellar Models are Reliable at Low Metallicity: An Asteroseismic Age for the Ancient Very Metal-Poor Star KIC 8144907
Daniel Huber, Ditte Slumstrup, Marc Hon +15
Very metal-poor stars ([Fe/H]<-2) are important laboratories for testing stellar models and reconstructing the formation history of our galaxy. Asteroseismology is a powerful tool…
Reggae: A Parametric Tuner for PBJam, and a Visualization Tool for Red Giant Oscillation Spectra
J. M. Joel Ong, Martin B. Nielsen, Emily J. Hatt +1
The upcoming second release of PBJam -- a software instrument for fitting normal modes ("peakbagging") -- supplements the simple power-spectrum model used in the first version to a…
