An outstanding example is SN 2009ip, which was classified as an SN IIn but three years later experienced an even larger, terminal explosion; the 2009 event was an SN impostor. In other cases of SNe IIn, it is possible that the initial outburst was an impostor, and the terminal explosion has not yet occurred. We propose to obtain deep, two-filter HST snapshot images of the sites of confirmed SNe IIn (> 9 years after outburst), in order to see whether the progenitor did indeed disappear and thus likely suffered a terminal explosion. The precise position of each of our targets will be known from post-eruption archival HST images. If instead we find an object at the site of the SN IIn, it is likely either the surviving progenitor, a companion star, or long-lived emission from the shocked CSM. The color of the star, obtained from the HST snapshot images, will provide a strong clue: LBVs are generally blue, ejecta-CSM interactors (with H-alpha emission) and RSG companions are red. The detection or nondetection of an object at the SN site will already provide fundamental information. However, to further explore the nature of any detected object, we will subsequently obtain essentially guaranteed, ground-based complementary spectra to search for medium/broad H-alpha emission characteristic of shocked CSM. ------------------------------------------------------------------------------------ Observations Description ------------------------ We wish to obtain deep (mag 26--27) WFC3 images of the sites of relatively old (>~ 9yr) SNe\, IIn that were previously imaged by HST after outburst but still visible 17731( 4) - 15-Nov-2024 16:13:29 - [ 2] (data available in the HST archive), so that we know precisely where they are located and thus where we should look. In ~30% of the cases, there are also archival HST images from before the outburst, so that we know the brightness of the progenitor (or have limits on it). Preliminary analysis suggests that a few with sufficiently good data appear to likely be LBVs (based on their luminosity and colors); more-detailed studies will be conducted in this program. The new HST images will be compared with the existing HST images to look for an object at the correct location. If no object is present, we will know that the progenitor probably suffered a terminal explosion --- the conclusion made by most other previous studies of massive-star SNe when an object is not detected at the precise location. (Perhaps it survived but is enshrouded in dust, a possibility we will explore with a future JWST proposal that would have been poorly motivated without an HST study first.) If, instead, an object is present, it is either the surviving star, long-lived emission from the SN shock, or a companion star or star cluster (light echoes are ruled out, being very faint and/or resolved). The object's color (from the HST snapshot data) will shed considerable light on these possibilities, which will be further explored with ground-based spectra; we will look for H_alpha emission and measure its width. Future HST proposals for multiband imaging will also be submitted, but we stress that this Cycle 32 proposal can be considered successful (the main goals will have been achieved) even if no future JWST or HST data are acquired. WFC3 is superior to ACS for our purposes, owing to its higher resolution and shorter overhead time for the relatively brief snapshot visits. Note that a substantial part of the host galaxies of the SNe will be imaged with WFC3, and the data can be used for many other studies, such as galaxy morphology, stellar populations, variable stars, star clusters, H II regions, and the search for future SN progenitors. We will remedy the CTE efficiency losses by using post-flash. After registering the new images astrometrically with the archival HST images to pinpoint the SN position, we will perform photometry on the new images using DOLPHOT v2.0 (Dolphin 2000). In most cases, there will either be a clearly detected isolated 17731( 4) - 15-Nov-2024 16:13:29 - [ 3] point source corresponding to the SN, or no flux evident at the SN position. When no object is detected, we will inject fake sources into the image adjacent to the SN position, and attempt to recover them to estimate a robust limit on the object's flux. In unusual cases, nearby sources such as stellar associations need to be simultaneously modeled to estimate the object's flux. Our top-priority desire is to go deep, in order to increase our chances of detecting a source at the position of the SN. However, we also want to obtain a color of any detected object. After running calculations on the WFC3 UVIS ETC, we decided to use the F475W (SDSS-g) and F625W (SDSS-r) filters, distributing the available time equally between them. (We also considered using only a single filter, F350LP, to go even deeper --- but the disadvantage is that this provides no color information, and the observed magnitude strongly depends on the object's SED.) The chosen filters are efficient and provide a commonly measured color. For a visit to be ~45 min long (close to the peak of the distribution of snapshot visits; http://www.stsci.edu/hst/HST_overview/documents/ uir/UIR_SNAP.pdf), there can be only one dithered, CR-SPLIT pair of 900s WFC3 exposures through each of two filters. From the ETC, we find that we reach S/N = 5 at limiting magnitudes of 26.6 (F475W) and 27.2 (F625W) when normalized to Johnson V using the spectrum of SN~IIn 2010jl about 7 yr after explosion and no extinction. (This input spectrum is representative of what we expect if the object exhibits SN ejecta-CSM shock interaction.) Similarly, instead using a B0 V Pickels input spectrum (there is no option for B0 I, closer to an LBV, but it should make little difference), we reach S/N = 5 at limiting magnitudes of 27.0 (F475W) and 26.1 (F625W). Adopting a representative magnitude of 26.6, the data will allow us to probe objects more luminous than roughly -6.0 mag at z = 0.007 (using H_0 = 71 km /s /Mpc), close to our average redshift. This is substantially fainter than typical LBVs and yellow hypergiants -7 to -12), and it is even in the general range of supergiant stars (-6 to -9; e.g., Humphreys & Davidson 1994; Smith et al. 2019). Thus, excluding a large amount of extinction produced by dust, we should be able to detect the surviving star, 17731( 4) - 15-Nov-2024 16:13:29 - [ 4] if one exists. Moreover, we will measure a broad-band color (approximately SDSS g-r), allowing us to distinguish between an LBV (g-r <~ 0 mag in quiescence, but sometimes red because of dust formation) and ejecta-CSM interaction (which typically produces strong H_alpha emission but almost no blue continuum at late times) or an RSG ( g-r > ~1 mag). In cases where an object is detected at the correct position, we will also obtain follow-up optical spectra with large ground-based telescopes to which our team has private access and/or nationally available time (through proposals). The main goal will be to search for intermediate-width (~1000 km /s) or broad H_alpha emission that would indicate that the object was a genuine SN whose ejecta are interacting with (and shocking) CSM. Such emission can often be detected in very faint objects (mag 25--26), since the flux density in the emission line far exceeds that in the continuum (e.g., Shahbandeh et al 2023; Sziros et al. 2024). If such H_alpha emission is not detected but the object is sufficiently bright for a decent spectrum to be obtained, that spectrum will allow us to classify the object (LBV, RSG, etc.), ruling out a companion or associated star cluster. If no object is detected, it will likely mean that the SN IIn did indeed explode; see, for example, the cases of SN 2005gl (Gal-Yam & Leonard 2009) and 7 other SNe (Van Dyk et al. 2013, 2023). However, there exists the possibility that it actually survived but is enshrouded in dust; the only way to test this is to propose future near-IR and mid-IR JWST observations -- but this program is the necessary first step. Our request is 21 snapshots in 21 visits (~45 min/visit). We have chosen 21 nearby (mostly z <~ 0.01, a few out to z = 0.02) SNe IIn that erupted >~ 9 yr ago, and for which HST images showing the SN in the first few years post-SN are available (so we can measure precise positions). ------------------------------------------------------------------------------------ 17731( 4) -
