Fitzpatrick Villanova University N ------------------------------------------------------------------------------------ Abstract Observations of nearby and distant galaxies (galaxy SEDS, lensed galaxies, and gamma ray bursts) have shown that dust with a wide variation in ultraviolet (UV) extinction properties (e.g., weak and strong 2175 Angstrom bumps) is the norm and not the exception. The Small Magllanic Cloud (SMC) is known to have dust spanning the full range of UV dust properties and is relatively nearby, making it the best galaxy to study the effects of environment (nearby star formation, gas-to-dust ratio, etc.) on the dust extinction. The SMC has sightlines with the traditional SMC extinction curve (no 2175 Angstrom bump, high far-UV rise) and one sightline with a much more Galactic extinction curve (2175 Angstrom bump, weaker far-UV rise). Unfortunately, there are only five existing SMC extinction curves making any correlation between extinction behavior and environment necessarily very tentative. We are proposing to determine the ultraviolet extinction curves toward 11 additional stars in the SMC thereby tripling the number of SMC extinction curves measured. The 11 reddened and 4 comparison stars for this proposal were picked from samples of hot stars with high quality spectral types and normal U through IRAC 8 micron SEDs (e.g., no Be stars). The new sightlines have different levels of star formation activity and infrared dust properties. In addition to helping understand the origin of the UV dust extinction variations in galaxies, the study of the spatial variation of UV extinction in the SMC also holds the promise of helping to understand the origin of the 2175 Angstrom bump. ------------------------------------------------------------------------------------ Observations Description ------------------------ We propose to obtain STIS low resolution observations in the 1150-3180 A wavelength range of a sample of 11 reddened SMC stars, which will allow us to more than triple the number of SMC sightlines for which UV extinction curves have been derived. In addition, we propose to observe 4 unreddened SMC stars which, when combined with archival observations of other unreddened stars (Walborn et al. 2000; Evans et al. 2004), will serve as the necessary comparison stars. The existing U-band through IRAC 8 micron (Gordon et al. 12258( 3) - 15-Dec-2010 01:46:19 - [ 2] 2010) flux distributions for all the proposed targets were examined to ensure that they are consistent with expectations for hot, normal stars and not suggestive of any stellar peculiarities (e.g., the Be phenomenon or other gross IR excess.). The existence of high quality near- and mid-infrared photometry of the reddened stars will enable high quality R(V) measurements. Our observational goal is to measure the full UV extinction curve of each sightline in our sample allowing the strength of the 2175 A bump and far-UV rise to be determined accurately. These features are broad (the 2175 A bump has a width of around 300-400 A) and can be well measured at the low spectral resolution of 10. Our goal is to detect the signature of a 5% 2175 A depression at 5-sigma confidence. Thus, our S/N goal is 100 at a resolution of 10. STIS/MAMA spectroscopy with the G140L and G230L gratings and the 52x2 slit is the most efficient observing strategy using HST (using COS would require 2X more time). HST is currently the only observatory capable of obtaining UV spectroscopy. Our targets have a range of brightnesses with V band magnitudes ranging from 14 to 16.71. For 2dFS0413 with 16.71 V mag and E(B-V)=0.26, the exposure time to get a S/N=10 at a resolution of 10 at 2200 A using STIS/FUV with the G140L grating is 853 s and at 1500 A using STIS/NUV with the G230L grating is 337 s. For our brightest star SMC5_003739 with 14.0 V mag and E(B-V)=0.36, the exposure time to get a S/N=10 at a resolution of 10 using STIS/FUV with the G140L grating is 171 s and using STIS/NUV with the G230L grating is 43 s. Even for our faintest target, only a single orbit is needed after accounting for the overheads (guide star acq., STIS acq., 2x auto-wavecals, and necessary buffer dumps). Thus, we can get a full UV spectrum (1150-3180 A) of each of our targets in under a one orbit. Given the relatively short exposure times for the brightest stars and the length of the visibility of the SMC per orbit, we will increase the exposure times to provide higher S/N detection limits as well as the ability to determine UV spectral types for comparison to the optical spectral types.
