Fresh Takes on Old (HST) Favorites: Uncovering Shocks in Well-studied Planetary Nebulae Planetary nebulae (PNe) present a dizzying array of morphologies, and the "origin story'' underlying this morphological diversity remains one of the unsolved problems of PN research. HST imaging first established the remarkable structural complexity of PNe, and HST narrow-band imaging still holds the key to understanding the mechanisms responsible for this complexity. We propose an HST GO/AR program consisting of first-time WFC3 atomic emission-line imaging of a sample of intensively-studied PNe, combined with comparative analysis of these new WFC3 images with the extensive library of archival WFPC2 narrow-band imaging available for these same iconic nebulae. The proposed HST/WFC3 observing program will unambiguously disentangle the zones of shocks and UV photoionization within the PNe, via spatial analysis ratios of forbidden line ([S II], N II], [Fe II] and [O I]) emission intensities to each other and to H recombination lines. The companion nebular expansion analysis obtained from comparison of late-1990's/early-2000's WFPC2 archival imaging data with the new WFC3 imagery will yield precise feature proper motions and, hence, precise nebular growth measurements. We will further employ JWST/NIRCam H2 and PAH imaging to establish the distribution of UV-irradiated molecular gas and dust within the target PNe. The proposed study will thereby provide stringent constraints on models of PN formation and structural evolution, and will serve as a pathfinder for future joint HST+JWST studies aimed at diagnosing the domains and evolution of shock-excited vs. photoionized plasma in a wide variety of astrophysical environments, from SNRs to AGN. Filters: We will obtain WFC3 images of each target PN in 8 narrow-band filters: UVIS module filters F631N+F673N+F658N+F656N for [O I] + [S II] + [N II] + H-alpha, and IR module filters F128N+F130N and F164N+F167N, respectively, for Pa-alpha and [Fe II] + off-line continuum. Feasibility and orbit requirements: The feasibility of the proposed program is demonstrated by Cycle 27 (2019-2020) WFC3 imaging surveys of NGC 7027 and NGC 6302 as well as the archival (1994-2008) WFPC2 imaging of the other target PNe that, together, represent the foundation for this proposal. Exposure times in the WFPC2 narrow-band filters corresponding to the aforementioned WFC3/UVIS filters ranged from a fews tens of seconds (F656N H-alpha) to a few hundred seconds (F673N [S II]), yielding high S/N imaging (see Fig. 1 of proposal), and WFC3 has greater sensitivity than WFPC in all filters. We can hence bundle the UVIS imaging into a single orbit, with total exposure times of 500-600 s per filter; exposures will be obtained via a combination of short and long integrations, to obtain unsaturated images in the brighter lines (i.e., H-alpha, [N II]). The IR module images will be obtained in two orbits (one for F128N+F130N, one for F164N+F167N), yielding sensitivities well below the threshold of the previously [Fe II]-detected nebulae (see Fig. 2). We will employ 4-point dither patterns to dither over the chip gap and provide effective CR elimination (for the UVIS module) and to maximize PSF sampling (for the IR module). The angular extents of the target PNe (from 30" to 100"; see Fig. 1 of proposal) are well matched to the WFC3 UVIS and IR FOVs, so each can be imaged with a single pointing. The PI, Joel Kastner (Rochester Inst. of Technology), has led numerous observational investigations of planetary nebulae over the past ~30 years. In particular, he led the most comprehensive surveys of near-IR H_2 and X-ray emission from PNe (Kastner et al. 1996, 2012), and is the PI of ALMA and Chandra/JWST studies of PNe, including several of the targets of this proposal. He has been among the lead organizers of the series of (eight) "Asymmetrical Planetary Nebula'' conferences almost since its inception. Co-Is Paula Moraga Baez and Diana Ryder were/are (respectively) former and present RIT graduate students under the PI's supervision. Paula, who has just begun a postdoctoral position at Western Ontario U, is skilled in HST, JWST, and ALMA data reduction and analysis (Moraga Baez et al. 2023, 2024). The proposed observations will be incorporated into Diana's PhD thesis at RIT and Paula's postdoctoral research at Western. Co-I Balick (U Washington) has a long track record of successful HST imaging of PNe, and has recently authored a series of papers on the structural evolution of bipolar PNe based on the comparison of HST imaging with AstroBEAR simulations. Co-I R. Montez (SAO) is an expert in the study of X-ray and UV emission from PNe and evolved stars generally. He was co-lead of the Chandra (X-ray) planetary nebula survey. Co-I Stavros Akras has extensive experience in ground-based emission-line imaging of PNe, and in modeling of PN emission line images and spectra. He has led several studies of near-IR [Fe II] and H2 imaging of PNe, including several of the targets of this proposal.
