So far, 17 extinction curves have been measured for the SMC, and most of these deviate strongly from those observed in the Milky Way, being steeper and exhibiting a small or nonexistent bump feature at 2175 A. The dust could therefore be fundamentally different under the low-metallicity conditions (0.2 solar) of the SMC, and we aim to study how the composition of dust grains plays a role in these differences. Depletions of gas-phase metals are a key observable to infer constraints on the dust grain composition, and have been measured for 18 SMC sightlines. However, a systematic study of extinction curves and depletion is currently not possible, because the existing SMC extinction curve and depletion samples share only 3 sightlines. We propose COS/FUV and STIS/NUV spectroscopic observations at medium resolution towards 4 stars in the SMC, for which high-quality extinction curves are already available. These data will be used to measure the depletions of the key constituents of dust, and expand the depletion+extinction sample size from 3 to 7. With this increase in sample size, we will be able to explore the relation between UV extinction curves and the dust composition for the first time in the SMC. These sightlines also extend the existing SMC depletion sample to higher column densities (1e22 cm-2), thereby probing the accretion of gas-phase metals by dust grains at higher densities. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will investigate the relation between extinction curves and the composition of dust grains -- as measured by depletions -- in the Small Magellanic Cloud. Depletions of gas-phase metals have been measured for 18 SMC sightlines. However, the existing SMC extinction curve and depletion samples share only 3 sightlines. We propose COS/FUV and STIS/NUV spectroscopic observations towards 4 stars in the SMC, for which high-quality extinction curves are already available, and expand the depletion+extinction sample size from 3 to 7. The 4 targets will be observed with deep COS/FUV G130M (1291) and STIS/NUV-MAMA E230M (1978) spectroscopy. The 53 orbits allocated to this program, will be distributed to achieve the following estimated SNR: For COS, SNR >= 25 at 1250 A. This can be achieved in 1 - 6 orbits per source. 17823( 6) - 02-Jan-2025 15:45:54 - [ 2] For STIS, SNR >= 13 at 2050 A. This can require long exposure times. The observations have been structured in visits of 3 orbits each, as recommended here: https://hst-docs.stsci.edu/stisihb/chapter-2-special-considerations-for-cycle-3 2/2-6-scheduling-efficiency-and-visit-orbit-limits. The COS visits start with an NUV imaging target acquisition, with a mirror and aperture combination that depends on the brightness. Then, the G130M/1291 exposures are taken for multiple orbits. We set up a mix of FP-POS3 and FP-POS4 observations, to achieve the benefits of dithering. This is achieved by setting a separate FP-POS per visit or per orbit. The estimated exposure time available is around 2400 s for the first orbit in a visit, and 2700 s for subsequent visits. The STIS visits start with a spectroscopic target acquisition, using the CCD in combination with the F28x50LP long pass slit, which is appropriate for the brightness of all sources. Then three long exposures with E230M/1978 orbit are performed, one exposure per orbit. Buffer times have been set according to the fill time reported by the ETC. The estimated exposure time available is around 2300 s for the first orbit in a visit, and 2800 s for subsequent visits. As per Change Request 92938, the target 2DFS0699 has been replaced by 2DFS3030. ------------------------------------------------------------------------------------ 17823( 6) - 02-Jan-2025 15:45:54 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 AZV-023 STAR, B3-B5 III-I RA=00H47M38.9029S +/- 0.1", J2000 V = 12.236 DEC=-73D22'53.86" +/- 0.1" Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
