Can Asteroseismic Structure Inversions Be Performed in Structure-Dependent Coordinates?
J. M. Joel Ong, Sarbani Basu, Willem Hoogendam +1
Yes. Unlike other applications of observational asteroseismology, "structure inversions" constrain the physical properties of stellar interiors in a model-independent fashion. Howe…
Anti-Solar Differential Rotation May Have Revived Magnetic Braking in the Subgiant 31 Aquilae
Travis S. Metcalfe, Jennifer L. van Saders, Thomas R. Ayres +16
Recent observations have shown that sufficiently slow rotation disrupts the organization of large-scale magnetic field in older main-sequence stars, leading to weakened magnetic br…
The sensitivity and behaviour of the curvature in the échelle diagram of red-giant stars
S. Hekker, Y. Elsworth, S. Basu +5
In the convective envelopes of relatively cool stars, oscillations are excited by turbulent convection. In these so-called solar-like oscillators, radial oscillation modes appear a…
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…
