The Effect of Different Methods for Accounting for -enhancement on the Asteroseismic Modeling of Metal-Poor Stars
Christopher J. Lindsay, J. M. Joel Ong, Sarbani Basu +2
Constraining stellar models using asteroseismic and spectroscopic observations is a powerful method for precisely determining the fundamental properties of stars in different kinem…
Precise Asteroseismic Ages for the Helmi Streams
Christopher J. Lindsay, Marc Hon, J. M. Joel Ong +6
The Helmi streams are remnants of a dwarf galaxy that was accreted by the Milky Way and whose stars now form a distinct kinematic and chemical substructure in the Galactic halo. Pr…
Asteroseismology with PBjam 2.0: measuring dipole mode frequencies in coupling regimes from main sequence to low-luminosity red giant stars
M. B. Nielsen, J. M. J. Ong, E. J. Hatt +7
PBjam is an open-source software package for measuring mode frequencies of solar-like oscillators. These frequencies help constrain stellar evolution models to precisely estimate m…
Resolving an Asteroseismic Catastrophe: Structural Diagnostics from p-mode Phase Functions off the Main Sequence
J. M. Joel Ong, Christopher J. Lindsay, Claudia Reyes +2
On the main sequence, the asteroseismic small frequency separation between radial and quadrupole p-modes is customarily interpreted to be a direct diagnostic of internal…
Signatures of Core-Envelope Rotational Misalignment in the Mixed-Mode Asteroseismology of Kepler-56
J. M. Joel Ong
Existing asteroseismic rotational measurements assume that stars rotate around a single axis. However, tidal torques from misaligned companions, or their possible engulfment, may b…
