The photospheric abundances of these white dwarfs reflect the bulk compositions of the accreted parent bodies, entirely analogous to meteorite abundance studies. HST ultraviolet spectroscopy has played a pivotal role in this field, providing abundance measurements of many elements inaccessible from the ground. The bulk compositions measured so far are broadly similar to those found in the solar system, suggesting that planet formation may be a fairly uniform process. The accuracy of the measured bulk compositions relies on the physically correct analysis of the white dwarf spectroscopy. However, all studies have so far used an assumption that remains untested - that the metals are uniformly distributed over the stellar surface. Given accretion proceeds via a geometrically thin disk, the validity of this assumption is far from obvious. We propose deep COS time-series ultraviolet spectroscopy of G29-38, the prototype white dwarf accreting from a debris disk. G29-28 undergoes non-radial pulsations, which heat localized regions on its surface that can briefly dominate the flux of the star. A spectrum obtained during such a heating event reflects the abundances of a small patch on the white dwarf surface. We will analyze a sufficiently large number of pulses to accurately map the distribution of metals across the entire surface of G29-38. Our results will be used to improve the modelling of debris-accreting white dwarfs, and lead to more reliable bulk compositions. ------------------------------------------------------------------------------------ Observations Description ------------------------ The goal of this program is to obtain time-tagged UV spectroscopy of the pulsating white dwarf G29-38 simultaneous to the Sector 16 TESS observations (2019, Sept 11 - Oct 7). The pulsations have periods in the range of two to 20 minutes. For the time-domain analysis, we require to pack the HST observations in the longest possibe contiguous COS visits, as irregular gaps in between multiple short visits will create a window function that is difficult to deal 15839( 8) - 31-Aug-2021 20:36:20 - [ 2] with. In an ideal world, the observations should be done in a single 35-orbit visit - which may not be feasible. In this first attempt, we opt for 5 x 7-orbit visits. Grouping the observations in fewer but longer visits would be helpful. We simulated both imaging and target acquisitions using a white dwarf model spectrum with the appropriate average temperature and surface gravity, scaled to the Gaia distance to the target, and find that the imaging acquisition using MIRROR-A and BOA is the fastest option. These average atmospheric parameters were measured from the previous COS/G130M observation of G29-38 (four orbits, data sets LBHK55010 and LBHK05010 ). We use the 1291A central wavelength because it provides the optimum wavelength coverage, including the broad quasi-molecular features at ~1150A and ~1400A, which is very temperature-sensitive, the Si II lines at 1260, 65, the CII lines at 1335, and the OI line at 1152A. Because the star is undergoing pulsations, we use the TIME-TAG mode and switch between FP-POS 3 and 4, and we will re-construct spectra phased on the pulsation modes. APT warns about inefficient FP-POS movements (4->3) - as we do those during Earth occultation, it does not affect the performance of the program. 2019-Aug-07: following the request of Juila we switched from an imaging acquisition to a spectroscopic acquisition as there is an M-dwarf near our target, and there is the risk it could end up in the second aperture during an imaging acquisition. 2021-Jun-17: the 90 sec overrun in the exposures was removed. And resubmitted. In addition the BETWEEN was modified to 2021-Aug-20 to 2021-Sept-16 2021-Jun-25: The exposure of each orbit was reduced by 45 sec to accomodate the visibility, as requested. ------------------------------------------------------------------------------------ 15839( 8) - 31-Aug-2021 20:36:20 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 V-ZZ-PSC STAR, DA RA=23H28M47.6365S +/- 0.0498", J2000 V = 13.03 DEC=+05D14'54.23" +/- 0.0352" Reference Frame: ICRS Extended: NO Comments: This target was observed with COS/G130M as part of HST program 12290, data set LBHK55010.
