Asteroseismology and Spectropolarimetry of the Exoplanet Host Star λ Serpentis
The bright star λ Ser hosts a hot Neptune with a minimum mass of 13.6 M⊕ and a 15.5 day
orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 days and …

Stellar Models are Reliable at Low Metallicity: An Asteroseismic Age for the Ancient Very Metal-poor Star KIC 8144907
Abstract 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 …

Realistic Uncertainties for Fundamental Properties of Asteroseismic Red Giants and the Interplay between Mixing Length, Metallicity, and
Asteroseismic modeling is a powerful way to derive stellar properties. However, the derived
quantities are limited by built-in assumptions used in stellar models. This work presents a …

Testing the Breakdown of the Asteroseismic Scaling Relations in Luminous Red Giants
Nearly all cool, evolved stars are solar-like oscillators, and fundamental stellar properties
can be inferred from these oscillations with asteroseismology. Scaling relations are …

A simple method to measure νmax for asteroseismology: application to 16 000 oscillating Kepler red giants
The importance of νmax (the frequency of maximum oscillation power) for asteroseismology
has been demonstrated widely in the previous decade, especially for red giants. With the …

Red Giant Rotational Inversion Kernels Need Nonlinear Surface Corrections
JMJ Ong - The Astrophysical Journal, 2023 - iopscience.iop.org
Asteroseismology is our only means of measuring the rotations of stars in their interiors,
rather than at their surfaces. Some techniques for measurements of this kind—" rotational …
