  bibo_abstract:
  - Rotation is typically assumed to induce strictly symmetric rotational splitting
    into the rotational multiplets of pure p- and g-modes. However, for evolved stars
    exhibiting mixed modes, avoided crossings between different multiplet components
    are known to yield asymmetric rotational splitting, in particular for near-degenerate
    mixed-mode pairs, where notional pure p-modes are fortuitously in resonance with
    pure g-modes. These near-degeneracy effects have been described in subgiants,
    but their consequences for the characterization of internal rotation in red giants
    have not previously been investigated in detail, in part owing to theoretical
    intractability. We employ new developments in the analytic theory of mixed-mode
    coupling to study these near-resonance phenomena. In the vicinity of the most
    p-dominated mixed modes, the near-degenerate intrinsic asymmetry from pure rotational
    splitting increases dramatically over the course of stellar evolution, and it
    depends strongly on the mode-mixing fraction ζ. We also find that a linear treatment
    of rotation remains viable for describing the underlying p- and g-modes, even
    when it does not for the resulting mixed modes undergoing these avoided crossings.
    We explore observational consequences for potential measurements of asymmetric
    mixed-mode splitting, which has been proposed as a magnetic-field diagnostic.
    Finally, we propose improved measurement techniques for rotational characterization,
    exploiting the linearity of rotational effects on the underlying p/g-modes, while
    still accounting for these mixed-mode coupling effects.@eng
