Extending asteroseismic magnetometry across the diverse landscape of magnetic structures
Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +5
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…
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…
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…
Testing tidal theory using Gaia binaries: the red giant branch
Janosz W. Dewberry, Yanqin Wu
Tidal interaction is a major ingredient in the theory of binary evolution. Here, we study tidal circularization in binaries with red giant primaries. We compute the tidal evolution…
Eccentricities of Close Stellar Binaries
Yanqin Wu, Sam Hadden, Janosz Dewberry +2
Orbits of stellar binaries are in general eccentric. These eccentricities encode information about their early lives. Here, we use thousands of main-sequence binaries from the Gaia…
Tidal synchronization trapping in stars and planets with convective envelopes
Janosz W. Dewberry
Tidal torques can alter the spins of tidally interacting stars and planets, usually over shorter timescales than the tidal damping of orbital separations or eccentricities. Simple…
On the damping of tidally driven oscillations
Janosz W. Dewberry, Samantha C. Wu
Expansions in the oscillation modes of tidally perturbed bodies provide a useful framework for representing tidally induced flows. However, recent work has demonstrated that such e…
