Receipt: # 14712-9 ----- Attempting Submission 10 (Mon Nov 06 20:42:01 GMT 2017) ----- HST-COS Ultraviolet Spectroscopy of B[e] Supergiant Stars in the Magellanic Clouds Massive stars end their lives as supernovae (SNe), which drive their host galaxy's chemical evolution by returning gas and dust to it. Some of the dust detected with SNe remnants should be created by the SN progenitor. It is therefore important to understand dusty mass loss from massive SN progenitors. One particularly poorly understood class of post-main sequence massive star, and therefore SN progenitor, is the B[e] supergiant (hereafter sgB[e]). SgB[e]s are mass-losing luminous B stars with a fast polar wind and a slower equatorial wind, the latter usually giving rise to dust production. Relatively few sgB[e]s are known. They usually have large thermal IR excesses due to large amounts of circumstellar dust, though recently-identified sgB[e]s in the low-metallicity Small Magellanic Cloud (SMC) have been found by Graus et al (2012) to be largely without circumstellar dust. To clarify their role as SN progenitors and the post-SN fate of the mass they lose, we request HST-COS ultraviolet (UV) spectra for a sample of 8 recently identified and 5 known sgB[e]s in the Large Magellanic Cloud and SMC. We will use the COS UV spectra to characterize the mass loss of the 3 recently-identified largely dustless sgB[e]s from the SMC, to compare to known dusty sgB[e]s. No other facility exists or will come into operation in the near future that can obtain these UV spectra. We will use the COS spectra to characterize the mass loss and determine basic stellar atmospheric parameters, which will reveal the evolutionary state of sgB[e]s and determine how their mass loss is related to their atmospheric parameters. This, in turn, will reveal their roles as mass-losing SN progenitors. We request ultraviolet spectra of 13 stars |- 4 recently-identified sgB[e] stars in the LMC, 4 recently-identified sgB[e] stars in the SMC, and 5 known sgB[e] stars in the LMC and SMC - to be obtained using COS on HST. We used the Exposure Time Calculator (ETC) available at http://etc.stsci.edu/etc/input/cos/spectroscopic/ to determine the exposure times for our targets. We ask for the G140L grating in FUV, with the 1280 central wavelength setting (B setting of <902-1195 Angstroms, A setting of 1282-2148 angstroms), with the Primary Science Aperture. In the ETC, we treat our stars's photospheres as if they are all B5III, 15000K, log(g)=3.5 Castelli and Kurucz model photospheres, assuming E(B-V) = 0.2 (Gummersbach et al 1995), applying extinction before normalization. The photosphere is normalized to the U band. 9 of our targets are in the CVZ, which means each orbit lasts 96 minutes. The other 4 targets are not in the CVZ, and at their declination, they have about 59 minutes of visibility according to the declination range for these targets (-60 > DEC > -80) in the Orbital Visibility Table in Section 6.1 of the HST Primer. For all 13 targets, we wish to observe each target using the G140L grating within one orbit. This is a total of 13 orbits. The 9 CVZ targets have 11.73 > U > 15.2. At 1400 Angstroms wavelength, assuming an exposure of 4920s (82 minutes), the estimated S/N ranges from 120 for the target with U = 11.73 to ~32 for the target with U = 15.2. The 4 non-CVZ targets, Hen S93, RMC 4, RMC 48, and MSX LMC 209, have U = 12.58, U = 12.61-11.74 (Zickgraf et al 1996 find some minor variability for RMC 4), U = 12.92, and U = 14.10 respectively. At 1400 Angstroms wavelength, assuming an exposure of 2700s (45 minutes), the estimated S/N ranges for these non-CVZ targets are 81 for Hen S93, 120-80 for RMC 4, 70 for RMC 48, and 40 for MSX LMC 209. All these S/N values are sufficient for our spectroscopic needs (Figure 3). The total overhead for each observation is 14 minutes. This breaks down into 6 minutes for guide star acquisition, 3 minutes for the ACQ/Image, and 5 minutes of G140L overhead. Altogether, then, each non-CVZ target requires 59 minutes of observation, while each CVZ target requires 96 minutes of observation (including overheads), which satisfies the limits of target variability from Table 6.1 of the HST Primer. A typical observation of a target would therefore be as follows. First the guide star would be acquired (6 minutes). Next, a target acquisition observation would be obtained (3 minutes). Then there would be about 5 minutes of COS G104L overhead. This would be followed by a single 2700 second exposure of COS in the G140L setting for non-CVZ targets, or a single 4920 second exposure of COS in G140L for CVZ targets.
