Asteroseismic imprints of strong non-axisymmetric fields in the cores of red giants
Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +5
To date, magnetic fields have been asteroseismically measured in nearly one hundred red giant cores. However, most analyses assume weak magnetic fields and slow rotation so that pe…
Extending asteroseismic magnetometry across the diverse landscape of magnetic structures
Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +6
Magnetic fields have now been asteroseismically measured in the cores of many red giants. However, most interpretations of these measurements assume that the magnetic field is far…
Saturn's Evolutionary History and Seismology: Survival of Deep Stably Stratified Regions in Evolutionary Models of Saturn Consistent with Ring Seismology
Yubo Su, Janosz W. Dewberry, Roberto Tejada Arevalo +2
With recent advances in the modeling of the solar system giant planets, rapid progress has been made in understanding the remaining questions pertaining to their formation and evol…
Isolating the gravitational influence of Uranus's winds requires close passages inward of the rings
Christopher R. Mankovich, Marzia Parisi, Damon F. Landau +1
Close orbits by a Uranus Orbiter and Probe (UOP) could be used to deduce Uranus's multipolar gravity field to higher precision and angular degree than the J2 and J4 currently measu…
Tidally driven inertial waves enhance eccentricity damping and spin evolution in planets and stars
Janosz W. Dewberry
Tidal interactions influence the orbital motions of binary star systems and extrasolar planets alike. Tides also affect stellar and planetary rotation rates. We demonstrate that in…
Instability and vertical eccentricity variation in global hydrodynamic disk simulations
Janosz W. Dewberry, Henrik N. Latter, Gordon I. Ogilvie +1
Many dynamical interactions can induce eccentricities in astrophysical accretion disks. Disk eccentricities in turn seed a variety of instabilities, even in ideal hydrodynamics. We…
