Topology and obliquity of core magnetic fields in shaping seismic properties of slowly rotating evolved stars
Shyeh Tjing Loi
It is thought that magnetic fields must be present in the interiors of stars to resolve certain discrepancies between theory and observation (e.g. angular momentum transport), but…
Effect of a strong magnetic field on gravity-mode period spacings in red giant stars
Shyeh Tjing Loi
When a star evolves into a red giant, the enhanced coupling between core-based gravity modes and envelope-based pressure modes forms mixed modes, allowing its deep interior to be p…
Magneto-gravity wave packet dynamics in strongly magnetised cores of evolved stars
Shyeh Tjing Loi
Magnetic fields are believed to be generated in the cores of massive main sequence stars, and these may survive on to later stages of evolution. Observations of depressed dipole mo…
Low-degree mixed modes in red giant stars with moderate core magnetic fields
Shyeh Tjing Loi, John C. B. Papaloizou
Observations of pressure-gravity mixed modes, combined with a theoretical framework for understanding mode formation, can yield a wealth of information about deep stellar interiors…
Effects of a strong magnetic field on internal gravity waves: trapping, phase mixing, reflection and dynamical chaos
Shyeh Tjing Loi, John C. B. Papaloizou
The spectrum of oscillation modes of a star provides information not only about its material properties (e.g. mean density), but also its symmetries. Spherical symmetry can be brok…
Torsional Alfvén resonances as an efficient damping mechanism for non-radial oscillations in red giant stars
Shyeh Tjing Loi, John C. B. Papaloizou
Stars are self-gravitating fluids in which pressure, buoyancy, rotation and magnetic fields provide the restoring forces for global modes of oscillation. Pressure and buoyancy ener…
A new angle for probing field-aligned irregularities with the Murchison Widefield Array
Shyeh Tjing Loi, Tara Murphy, Iver H. Cairns +5
Electron density irregularities in the ionosphere are known to be magnetically anisotropic, preferentially elongated along the lines of force. While many studies of their morpholog…
Density duct formation in the wake of a travelling ionospheric disturbance: Murchison Widefield Array observations
Shyeh Tjing Loi, Iver H. Cairns, Tara Murphy +8
Geomagnetically-aligned density structures with a range of sizes exist in the near-Earth plasma environment, including 10-100 km-wide VLF/HF wave-ducting structures. Their small di…
Dynamic reconstruction for atom probe tomography
Baptiste Gault, Shyeh Tjing Loi, Vicente J. Araullo-Peters +7
Progress in the reconstruction for atom probe tomography has been limited since the first implementation of the protocol proposed by Bas et al. in 1995. This approach, and those su…
Quantifying ionospheric effects on time-domain astrophysics with the Murchison Widefield Array
Shyeh Tjing Loi, Tara Murphy, Martin E. Bell +39
Refraction and diffraction of incoming radio waves by the ionosphere induce time variability in the angular positions, peak amplitudes and shapes of radio sources, potentially comp…
Real-time imaging of density ducts between the plasmasphere and ionosphere
Shyeh Tjing Loi, Tara Murphy, Iver H. Cairns +38
Ionization of the Earth's atmosphere by sunlight forms a complex, multi-layered plasma environment within the Earth's magnetosphere, the innermost layers being the ionosphere and p…
G306.3-0.9: A newly discovered young galactic supernova remnant
Mark Reynolds, Shyeh Loi, Tara Murphy +14
We present X-ray and radio observations of the new Galactic supernova remnant (SNR) G306.3-0.9, recently discovered by Swift. Chandra imaging reveals a complex morphology, dominate…
