Morphological Types

• Primary core outline, which is the most
  prominent structure seen in short exposures
• DEPENDS ON GOOD SPATIAL RESOLUTION
• Only one core classification per object, like a
  species
• Secondary large-scale symmetries
• DEPENDS ON DEPTH OF EXPOSURES
• Tertiary relatively prominent extended features
  near the core
• LOBES, SHELLS, HALOES, BOW WAVES
• DEPENDS ON DEPTH OF EXPOSURES
• Tertiary small-scale features
• ANSAE, JETS, SPIKES, FILAMENTS, ETC.
• DETECTION IS SENSITIVE TO RESOLUTION AND FILTER

6
Primary Core Outlines

• Round (17 of classifiable, 13 of all)
• Closed Elliptical (36 27)
• Barrel, or open elliptical (29 22)
• Pinched waist (9 6)
• Equatorial disk (9 7)
• Amorphous or complex (unclassifiable) (11)
• Poorly resolved (unclassifiable) (13)

7
Primary Core Outlines

• Round the core has a closed round outline
• Closed Elliptical the core has a closed
  elliptical outline
• Barrel, or open elliptical

8
Primary Core Outlines

• Pinched waist
• the core has a pinched, perhaps darkened waist
• Equatorial disk
• the core is dominated by a equatorial thin disk
  or ring

9
Primary Core Outlines

• Amorphous or complex (unclassifiable)
• Poorly resolved (unclassifiable)

10
2ry Large-Scale Symmetry

• Multiple Symmetry Axes (8)
• Spiral or Point Symmetry (5)
• Orthogonal Extensions (8)

11
3ry Prominent Core Extensions

• Lobe Pairs (open and closed) (27)
• Peanut, or Pinched Barrel (4)
• Encapsulating Bow Wave (2)

12
3ry Prominent Core Extensions

• Shells (adjacent to core smooth surface
  brightness) (20)
• Haloes (large, faint, limb brightened, sometimes
  irregular) (4)

13
4ry Small-Scale Features

• Ansae or Knots (in regular pairs) (10)
• Jets or Bowshocks (in regular pairs) (3)
• Spikes and Necklaces (2)

14
4ry Small-Scale Features

• Knotty Edges (9)
• Filamentary or Flocculent Edges (12)
• Possible Neutral Edges (3)

Remember!

• The images come from highly biased and incomplete
  samples and surveys
• The image details depend on exposure depth,
  spatial resolution, filters, field, other
  observables
• Morphologies are a multidimensional continuum
  names can create artificial boundaries
• More HST images coming prePNe and PNe
• Combine with kinematic data
• e.g., The SPM Kinematic Catalog of PNe (in
  progress)
• J.A. Lopez, M. Richer, H. Riesgo, W. Steffen, J.
  Meaburn, G. Garcia-Segura, M. Bryce, K.
  Escalante
• Combine with IR x-ray images

16
X-Ray vs Optical Core Morphologies

• All nine extended x-ray PNe are contained within
  closed cores and lobes (so far, anyway)
• All seven non-detections of PNe have open
  geometries
• Suggests that punctures deflate the hot bubble
  gas cools by expansion
