A First Investigation of the UV Extinction Properties of Interstellar Dust in M33
It is well known that the standard Milky Way UV extinction curve does not hold even in the most nearby galaxies, the LMC and the SMC. But, it is not even known whether the standard curve holds throughout our own galaxy because our position in the disk of the Milky Way, where extinction is high, prevents us from seeing most of our galaxy at UV wavelengths. We have a unique opportunity, while we still have the capability to obtain UV spectra, to investigate the UV extinction properties across another spiral galaxy in the Local Group, M33. The small aperture and high sensitivity of HST/STIS are ideal for obtaining UV spectra of stars in the crowded fields of M33. We propose to observe 8 stars in M33 which will provide good spatial coverage. We are choosing sightlines that lie in the footprint of the M33 Legacy Survey which extends the Panchromatic Hubble Andromeda Treasury (PHAT) survey. Focusing our study on the detailed properties of M33 dust grains via UV spectroscopy with HST/STIS will mean that we can directly connect the variations seen in the UV extinction curves with their environments. By selecting our sightlines in the M33 PHAT survey region, we will be able to probe a variety of potential correlations between dust grains and their environment. This proposal is part of a long-term program to investigate the extinction properties of interstellar dust across a sample of Local Group galaxies, also including M31, with different global characteristics such as metallicity and star formation activity. There is a metallicity gradient across M33 from solar to sub-solar that will be sampled with our proposed sightlines.
We plan to observe a total of 8 stars, listed in Table 1 and in the Target Summary. The stars require 2 orbits each for a total of 16 orbits. The visibilityfor M33 (Dec ~+40 deg) is approximately 54 minutes per orbit. Using the Phase II Orbit Planner, including the Guide Star and STIS acquisition overheads, we find that we will get about 2800 s per orbit on M33 targets with the G230L and G140L gratings. Since we are using the 0.2 x 0.2 slit, no peakup is required. Each target has a single 2-orbit visit with no repeat visits, one orbit for each grating.
