Receipt: # 16263-2 visit planner was run Diagnosing a New Species of Dusty Debris: the Chameleon Debris Disk Two new, potentially causally correlated, observational phenomena have recently been discovered in spatially resolved imagery of debris disks: outward moving features traveling at super-Keplerian velocities and changes in the color of the AU Mic debris disk. To date, these are the only moving structures and the only observed color change seen in spatially resolved debris disks. We propose to use the only observational facility capable of yielding high fidelity optical coronagraphic spectroscopy of AU Mic's disk, HST/STIS, to obtain second epoch G750L and first epoch G430L spectroscopy. These data will enable us to: a) quantify color changes in the disk over a 2x greater time baseline (16 yrs) than previously achieved; b) determine whether the disk's color between 30-45 au continues to change as additional fast moving features pass by; c) better quantify the size of dust grains whose spatial distribution has changed; and d) confirm and better quantify whether small grains populate small (10-30 au) stellocentric distances. Derived grain size distributions will be linked to dynamical models proposed for the origin of fast moving features in this system. The observational setup of our program necessarily follows GO-12512, a precursor program that observed the same targets in G750L with this technique. Each target consists of a sequence of observations: 1. Standard acquisition 2. Peakup - We do the peakup in the smallest available aperture, in BOTH x AND y. Then, for both G430L and G750L gratings, we do the following: 3. Point source spectrum outside of fiducial in 52x0.2 slit 4. Fiducial spectra - maximum integration time for bright sources set by time to saturation of stellar scattered light at edge of the fiducial, minimum integration time for faint sources set by time to achieve source noise limited spectra. Integrations are CR-SPLIT for CR removal. In Phase I, we specifically requested the F2 fiducial (unsupported aperture) because of its superior light rejection. For the science objects, we specify a narrow range of acceptable ORIENTs to position the slit along the disk major axis. We therefore require an absolute orient between 351.6 to 353.6 (+/- 1 degree of tolerance around 352.6). We STRONGLY desire to use the EXACT orient as used in GO-12512, 352.0 degrees. We ask our PC to try to get and maintain this exact setting if at all possible. For G750L only, we do a 5. Flat ------ Calibration Justification ------- PSF observation - This is necessary to be able to subtract off the stellar contribution at every position and wavelength to reveal the spectrum and spatial profile of the disk. Peakup -We want exceptionally good positioning under the fiducial in order to be able to cleanly subtract off the PSF contribution. For all targets (objects and PSFs), we do the peakup IN BOTH X AND Y in the smallest available aperture. Point source spectrum outside of fiducial in 52x0.2 slit - This is necessary for calibrating out any spectral differences between the target and PSFas well as for aiding in photometric calibration G750L flat -CCDFLAT taken with 52X0.2 slit for better defringing of extended-source spectra (narrower slit would be better for defringing point-source spectra). PI John Wisniewski has 10+ years of expertise in high contrast imaging of protoplanetary and debris disks using ground-based and HST instrumentation (including coronagraphs on STIS, ACS, and NICMOS). Wisniewski is PI of GO-15219, which is a complementary AU Mic broad-band imaging project of our proposed program. Co-I Jamie Lomax is one of the few astronomers who have hands-on experience successfully reducing, analyzing, and publishing HST/STIS coronagraphic spectroscopy. Her Lomax+ 2018 paper presented such observations of AU Mic, that indicated its color had changed from earlier epoch broad-band imaging. Co-Is Carol Grady, John Debes, and Alycia Weinberger are experts in the reduction and analysis of STIS coronagraphic imagery and with high-contrast imaging in the NIR from the ground as part. Weinberger and Roberge have led previous programs utilizing STIS' coronagraphic spectroscopy mode. Co-I Anthony Boccaletti is leading high contrast imaging of AU Mic from the ground using VLT/SPHERE, and is the lead author of the studies reporting the discovery and follow-up of outward moving features in its disk (Boccaletti+ 2015; Boccaletti+ 2018). Co-I Elie Sezestre has developed one of the leading dynamical models to explain the origin of moving features in AU Mic's disk. co-I Jessica Arnold is leading efforts to model grain size distributions from coronagraphic spectroscopy of debris disks. Co-I Adam Kowalski is a leading expert in high energy flares from Solar-analogs and M dwarfs, and is leading a large multi-wavelength flare survey of AU Mic.
