SMC O stars provide an unrivaled opportunity to probe star formation, evolution, and the feedback of massive stars in an environment similar to the epoch of the peak in star formation history. Two recent breakthroughs in the study of hot, massive stars have important consequences for understanding the chemical enrichment and buildup of stellar mass in the Universe. The first is the realization that rotation plays a major role in influencing the evolution of massive stars and their feedback on the surrounding environment. The second is a drastic downward revision of the mass loss rates of massive stars coming from an improved description of their winds. STIS spectroscopy of SMC O stars combined with state-of-the-art NLTE analyses has shed new light on these two topics. A majority of SMC O stars reveal CNO-cycle processed material brought at their surface by rotational mixing. Secondly, the FUV wind lines of early O stars provide strong indications of the clumped nature of their wind. Moreover, we first drew attention to some late-O dwarfs showing extremely weak wind signatures. Consequently, we have derived mass loss rates from STIS spectroscopy that are significantly lower than the current theoretical predictions used in evolutionary models. Because of the limited size of the current sample (and some clear bias toward stars with sharp-lined spectra), these results must however be viewed as tentative. Thanks to the high efficiency of COS in the FUV range, we propose now to obtain high-resolution FUV spectra with COS of a larger sample of SMC O stars to study systematically rotation and wind properties of massive stars at low metallicity. The analysis of the FUV wind lines will be based on our 2D extension of CMFGEN to model axi-symmetric rotating winds.

We propose to obtain high-resolution (R=20,000) COS FUV spectra of 22 O stars in the SMC. We request to observe each target in a sequence of 4 science exposures with COS, using gratings G130M (λ1291, λ1327) and G160M (λ1577, λ1623). This sequence provides full coverage without gap of the FUV spectrum between 1132 and 1798?. Overlapping segments will be co-added to improve the final SNR. Thanks to the high efficiency of COS in the FUV, we will achieve a sufficient SNR, typically SNR ≈ 30 per resolution element, in a single HST orbit for each target. Target acquisition should be carried out in the same mode (dispersed FUV mode) with an ACQ/SEARCH followed by the peak-up procedure. Each visit is constructed in the same way, with no special requirements but limited ORIENT range for 4 stars for increased instrument safety (see below). Using COS Exposure Time Calculator, we have estimated count rates for each star and each grating configuration. We have used Castelli-Kurucz model atmospheres with the closest spectral type, normalized to V magnitudes. Photometry was extracted from Massey's UBVR CCD survey of the Magellanic Clouds (2002, ApJS, 141, 81) or from Evans et al. (2006, AA, 456, 623) for stars in NGC 346. We derived color excesses, E(B-V), and applied a SMC extinction law. Two stars, AV 372 and AV 135 (G130M only) have total count rates for the two channels between 25,000 and 30,000 c/s. We have selected the ACCUM mode in these cases. All other stars can be observed in the TTAG mode. Maximum total counts (both channels) are 18,000 c/s in G130M and 15,000 c/s in G160M, with a maximum count rate of 11,000 c/s in channel B. About half the stars exceed the 6,000 c/s limit in channel B; however, these stars are not known or expected to exhibit large or irregular variations. Buffer times have been estimated for each single TTAG observation (2/3 of the ETC values). Finally, the maximum local count per pixel is always a factor of 2 (G130M) or of 3 to 10 (G160M) lower than the limit. FOS or STIS/G140L fluxes are available for a few targets. We derive total count rates that are 10 to 30% higher than from the V magnitude normalization. Higher count rates stem from using solar metallicity model atmospheres (metal-poor SMC stars have bluer spectra) and uncertainties in the extinction law (we used the SMC law, while we have both a contribution from the Galactic foreground and SMC). Count rates have a safety margin of 75% (G130M) or of a factor of 2 (G160M); even if the count rates with normalization at V are systematically underestimated by 20-30%, we keep a sufficient safety margin. Possibly, some counts may be lost in the TTAG mode for the brightest targets, but this would be of limited consequence for the final SNR. Finally, we run the BOT tool for all targets and inspect the stellar fields with Aladin. There are no bright stars at proximity of our targets that may be a safety concern for COS. For 3 stars in NGC 346 and AV 267, there is relatively bright but unknown stars at the edge of the BOA area. For increased safety, we have thus limited the range of ORIENT to avoid the risk of these stars falling in the BOA during the acquisition procedure.
