Puzzlingly, unlike every other debris disk observed thus far, existing low-S/N visible wavelength images of HD 53143 show that the micron-sized dust around HD 53143 does not resemble a circumstellar ring--rather, it looks like two isolated clumps of material. New ALMA observations show that the underlying distribution of larger planetesimals is indeed ring-like, but very eccentric and mis-aligned with the visible wavelength clumps. Further, the ALMA observations reveal 5-sigma excesses just interior to the circumstellar ring, suggesting structure in the planetesimal population that may be connected to the visible wavelength clumps. We propose high-S/N coronagraphic imaging of HD 53143 using HST STIS to reveal the peculiar nature of this unique debris disk and search for signs of planet-induced disk structure or collisional activity. In addition to revealing the structure of the disk, these high-S/N images will allow us to measure the optical properties of the debris disk dust to constrain its composition, size distribution, and provide critical measurements of debris disk properties that will inform future exoplanet-imaging missions. ------------------------------------------------------------------------------------ Observations Description ------------------------ ----- Summary ----- We will be observing one science target, HD 53143, and one PSF reference star, HD 58895, using the STIS WedgeA1.8 coronagraphic mask. Our goal is to maximize the SNR of two "clumps" of circumstellar debris around HD 53143, which are at a PA of 145 deg E of N and 325 deg E of N, while obtaining decent roll angle coverage. We desire to maximize exposure time on the clumps by minimizing coronagraphic occultation of the clumps. This requires an absolute orientation of the WedgeA1.8 mask as well as a small total roll coverage. Total roll angle coverage is desired to be ~16 deg, with the WedgeA1.8 mask oriented perpendicular to the clumps. This observing program requires a total of 15 orbits. ----- Targets ----- 16202( 4) - 12-Oct-2021 19:50:40 - [ 2] Science Target: HD 53143 G9V star, V=6.8, B-V=0.8 PSF reference HD 58895 G3IV star, V=6.5, B-V=0.7 Previous program GO 12228 adopted HD 59780 (B-V=0.95) as the reference star, but this may have a color mis-match that resulted in unsubtracted PSF residuals. Our adopted star above is a better color match (and the mis-match that exists has the opposite sign compared to HD 59780) and is only at 6 deg separation. We note that an alternative PSF reference star is HD 53706, which has an *excellent* color and magnitude match. However, this star is at 18 deg separation and has a 1-mag brighter (V=5.2) companion at 20". ----- Schedulability & Timing ----- We split our 15 orbits into 3 groups of 5 orbits to improve schedulability. Each group consists of a non-interruptible sequence of 5 visits with the first 2 visits on the science target, the middle visit on the PSF reference star, and the last two on the science target. All 5 visits within a group are linked by a "Timing/After Visit" requirement to sequence observations. ----- Orientation ----- We require that the WedgeA mask be placed roughly perpendicular to the celestial PA of the "clumps" we are observing. Given the clumps are at a PA of 145 and 325 deg E of N, this means an orientaton of 100 or 280 deg (this was determined by using Aladin to visualize the 52x2 STIS slit aperture, which is oriented parallel to Wedge A). Given our ~16 deg spread in roll angles, we therefore require the first visit to have an absolute orientation of 100+16/2=108 deg or 280+16/2=288 deg. We allow for +/- 1 deg about this angle, such that allowable absolute orientations are 107-109 deg or 287-289 deg. Every subsequent science target visit is decreased in orientation by 1.5 deg, all benchmarked to the first visit. There are no orientation constraints on the PSF reference star. ----- Exposure Times ----- Target Acq: times were calculated using the STIS Exposure Time Calculator assuming a K0V star with V mag = 6.8, suitable for both science target and PSF reference star, and reflect the time to achieve an SNR>=100. Science Exposures: We used the 300 second GO12228 WedgeA1.0 observations of HD 53143 to estimate exposure times. Full well with gain = 4 is 34, 000 counts. We aim for exposure times that achieve <80% of full well, or <27, 000 counts to avoid saturation issues. Interior to 1", the GO 12228 observations are saturated. We fit the total counts vs separation beyond 1", where all pixel 16202( 4) - 12-Oct-2021 19:50:40 - [ 3] counts were <27, 000, using a 2nd order polynomial and extrapolated it inward to a separation of 0.9" (at the edge of our proposed WedgeA1.8 observations) to find an expected total counts of 34, 000. Scaling this down to 27, 000 would require shortening the exposure time from 300 s to 240 s to avoid all saturation in our exposures. In the end, we deemed the extra read noise not worth pushing the useful IWA from 1" to 0.9"--1" should be more than sufficient to test whether the azimuthally symmetric halo observed in GO12228 is real. Thus, we stick with 300 sec subexposures achieved with 2400 s exposures and CR-SPLIT=8. We choose NAXIS2 = 427 to achieve the same large FOV as GO12228 (+/-11"). Decreasing this to 310 would cover +/-8" and be adequate for imaging the HD 53143 clumps. However, the small increase in useful science time is not worth losing the potential discovery space of a faint extended halo given the depth of our observations. To obtain equal well depth with the reference star (V=6.581), we must reduce exposure times by a factor of 10^(-0.4*(6.803-6.581)) = 0.815. Thus we require 245 sec sub-exposures for the PSF reference star. To maximize use of the orbit while achieving this sub-exposure, we split PSF reference expoures into 2 exposures. ------------------------------------------------------------------------------------ 16202( 4) - 12-Oct-2021 19:50:40 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 HD-53143 STAR, CIRCUMSTELLAR RA=06H59M59.6555S, J2000 V = 6.803 MATTER, DISK, G V-IV DEC=-61D20'10.25" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
