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…
Acoustic modes in M67 cluster stars trace deepening convective envelopes
Claudia Reyes, Dennis Stello, Joel Ong +3
Acoustic oscillations in stars are sensitive to stellar interiors. Frequency differences between overtone modes -- large separations -- probe stellar density, while differences bet…
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…
