  bibo_abstract:
  - "We present deep, narrowband Gemini North/GMOS images of the Pa 30 nebula that
    reveal rich small-scale\r\nstructure in the ejecta filaments. In [S II], the number
    of detected filaments increases by about an order of\r\nmagnitude compared to
    previous studies. The imaging further reveals that the filaments are not smooth
    radial\r\nstreaks, but instead are composed of cascades of knots or clumps. The
    images in [O III] yield the first confirmation\r\nthat previously detected diffuse
    [O III] emission in fact originates from the same [S II] filaments. We measure
    a\r\nnebula center consistent with the position of the central star, indicating
    that the remnant has not received a large\r\ntransverse kick. The 3σ upper limit
    on the velocity of the stellar kick is ≲100 km s\r\n−1\r\n. Cross-sectional profiles
    of\r\nthe filaments in [S II] and [O III] show a central peak on top of a nebula
    background, the latter being likely due to\r\ndiffuse emission or unresolved filaments.
    The median [S II] width of 0.7 is slightly broader than the 0.50 seeing,\r\nproviding
    some evidence of partially resolved filaments and implying a characteristic knot
    diameter of ∼1016 cm.\r\nThe ≈1″ widths measured in [O III] are consistent with
    the poorer seeing of the oxygen images. The discovery of\r\nthis clumpy substructure
    provides a new observational constraint on models for the origin and evolution
    of the\r\nremarkable filamentary ejecta of Pa 30.@eng"
