The mystery of Dual Filamentary structures in Nebulae, is solved by the new physics primary micro Herbig Haro dual black hole systems. See by the new physics of new rigid String model, with Penrose- Vuyk Trapped Spacetime horizon effects around all string knot black holes, even around micro- interference black holes created by stars, comets, sunspots, tadpoles ball lightnings etc. see: https://vixra.org/author/leo_vuyk
In Opposition to the the standard model:
Single and dual tadpole micro black holes all seem to have a Penrose-Vuyk trapped spacetime horizon able to attract and closeby repel all fermions into a pushing plasma tail of the black hole . The plasma atil is influenced by local gravitational hotspots like other micro and macro lack holes.

Text: We propose a theory where the magnetic fields control the sculpting and evolution of small-scale filaments.
This theory demonstrates how the substructures may form magnetized flux ropes that are twisted around each other, in the shape of double helices. Similar structures, and with similar origin, are found in many other astrophysical environments.
Fig. 3 a Large Y-shaped filament found in NGC 3132, with the stem pointing toward the central regions of the nebula. Image size:16′′ × 21′′. Image credit: NASA and the Hubble Heritage Team.
Fig. 4 a Cometary knot with a wavy tail just inside the shell in the north-north-western part of NGC 7293. Image credit: NASA, NOAO,ESA, the Hubble Helix Nebula Team, M. Meixner (STScI), and T.A.Rector (NRAO). The tail points nearly radially outwards from the cen-tre of the nebula. Image size, 23′′ × 26′′. The structure of the tail is interpreted as two filaments winding around each other and closing nearthe bottom of the image. b Drawing of the knot and tail emphasizingthe twisted structure.
Below: other examples of Two filaments coming together, however creating a strong splitting and multiplying process to form also equal sized hotspots which seem to create also Herbig Haro systems.
