  bibo_abstract:
  - Mixed modes are observed in many low-mass evolved stars. They provide information
    about core rotation rates of these stars, which are lower than predicted by stellar
    evolution models. The mixed modes themselves have been invoked as an angular momentum
    (AM) transport mechanism, but estimating their transport efficiency requires knowledge
    of their amplitudes. We constrain, for the first time, the mixed-mode amplitudes
    in 2D hydrodynamical simulations of a 1.3M⊙ red giant using the code MUSIC. We
    perform two simulations with outer radial truncations at fractional radii ro/r⋆
    = 0.90 and 0.98. We compare the modes in the simulation with those found using
    both GYRE and a Dedalus eigenvalue solver. Excellent frequency agreement is found
    for all p-dominated modes, with minor discrepancies for g-dominated modes, especially
    in the frequency range [60, 240] μHz. We find excellent eigenfunction agreement
    for all modes except those in this frequency range. According to empirical predictions,
    the largest kinetic energies are located around Vmax= 312.μHz, but in both simulations,
    the modes with frequencies of ν < 50 μHz have the largest kinetic energies. In
    the simulation with r/r⋆ = 0.98, the simulated modes have extrapolated surface
    velocities comparable to the empirical predictions, with the highest surface velocities
    in a bell-shaped curve peaking around ν = 700 μHz. The extrapolated surface velocities
    of the low-frequency modes are small and thus hard to observe, but their large
    kinetic energies deeper in the interior could significantly impact AM transport,
    which has not yet been investigated.@eng
