12520( 2) - 28-Jun-2011 10:36:01 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 12520 Version: 2 Check-in Time: 28-Jun-2011 10:36:01 STScI Edit Number: 0 Title Testing Rotational Mixing in Massive Stars: Boron in the Galactic Open Cluster NGC 3293 ------------------------------------------------------------------------------------ Type Cycle GO 19 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Charles R. Proffitt Computer Sciences Corporation CoI: Dr. Daniel J. Lennon Space Telescope Science Institute - ESA N CoI: Dr. Norbert Langer Universitat Bonn, Argelander Institute for N Astronomy CoI: Ms. Ines Brott University of Vienna N ------------------------------------------------------------------------------------ Abstract Recent observational advances have shown that chemical mixing in the envelopes of early-B stars is more complex than had previously been realized. The abundance patterns seen do not match the simple theoretically expected patterns, and there appear to be processes other than rotation that can also cause mixing. These complicating effects make it difficult to test or calibrate current stellar evolution models that include rotation with the currently available data, especially as most existing boron observations are biased towards intrinsically slow rotating stars. We have identified a sample of near-turnoff stars in the 10 Myr open cluster NGC 3293 which can now be efficiently observed with the COS G185M setting in which the earliest stages of rotationally driven mixing should have noticeably depleted the surface boron abundances. These observations will place stringent new constraints on models of rotationally driven mixing in early-B stars. ------------------------------------------------------------------------------------ Observations Description ------------------------ One target will be observed in each of the ten visits. The brightest target (#02) will be observed with STIS E230H 1963 in ACCUM mode. The STIS ACQ will be done with F28X50OII, and the ACQ/PEAK with the G430L. We will use four of the 0.2x0.06 stis FP-SPLIT slits for the observations and the 0.2x0.06FPB for the peakup. We substitute a STIS GO wavecal at the end of the orbit for a standard auto-wavecal. The other targets will be observed with the COS G185M using the 1971 setting and all four FP-POS positions. Targets, 3, 4, 7, 8, 10, 12, & 19 will be observed using ACCUM mode, while targets 23 & 24 will use time-tag. For the targets observed in COS ACCUM mode we will take two subexposures at each FP-POS position to minimize the effects of OSM drift and/or photospheric velocity variations in the target. COS acquisitions will use the same dispersed light G185M grating as the science. In principle, we could use 12520( 2) - 28-Jun-2011 10:36:01 - [ 2] NUV imaging with the BOA, but that would leave a difficult BOP issue for the PSA aperture in this crowded cluster field. To simplify the matching of targets and visits, we specify as the primary names for all of our targets the designations given to stars in this cluster by Evans et al 2005 (A&A, 437, 467), and we set both the target # and the visit # to correspond the Evans et al's number for that star. Simbad searches on these names can be done with designations like "Cl* NGC 3293 ESL 2" for his star #2. Many, if not most of these stars are beta Cepheid variables, but none of the stars have large amplitudes. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- Target BOP For most of our targets low-dispersion, large aperture IUE observations are available. For stars with low-dispersion, large aperture IUE data we used the observed SWP+LWR or LWP spectra as the ETC input. For all stars we also interpolated Kurucz models tailored to the Vmag, Teff, logg, & E(B-V) given by Dufton et al. 2006, A&A, 457, 265. Online data from Dufton is available at http://vizier.cfa.harvard.edu/viz-bin/VizieR?-source=J/A+A/457/265 Stellar Parameters from Dufton et al, Name Vmag B-V SpType Teff logg E(B-V) mag K [cm/s2] mag 3293-002 6.73 0.07 B0.7 Ib 23000 2.80 0.27 3293-003 7.61 0.11 B1 III 21100 2.90 0.30 3293-004 8.03 0.02 B1 III 21500 3.00 0.21 3293-007 8.25 0.18 B1 III 22800 3.10 0.38 3293-008 8.59 0.05 B1 III 21500 3.25 0.24 3293-010 8.77 0.00 B1 III 21000 3.15 0.18 3293-012 8.95 0.06 B1 III 21500 3.30 0.25 3293-019 9.27 -0.04 B1 V 25000 3.85 0.18 3293-023 10.01 -0.05 B1.5 III 20500 3.40 0.13 3293-024 10.01 -0.01 B1.5 III 20500 3.50 0.17 12520( 2) - 28-Jun-2011 10:36:01 - [ 3] For all stars where we have IUE data, the observed fluxes are always slightly less than the model predictions, but in most cases differences are < 10% (for ESL003, the IUE observation is about 15% smaller). So we are confident that all stars are within allowed limits, even though ESL003 and ESL004 are getting rather close to the 30000 c/s per stripe limit for COS NUV spectra of some of our targets. Results from Kurucz models tailored to Dufton's parameters above are given below. We used synphot to interpolate the standard Kurucz solar metallicty grid to the Teff and Logg values given, and also added Dufton's listed amount of extinction. Below we report the predicted global rate as well as the peak stripe rate and peak local rate, and the ETC ID #.

(COS.sp.181682). No star this bright is within 0.5 degrees of NGC 3293, so there is no need to be concerned about where the BOA is pointing during our PSA COS observations. For the COS targets in the PSA, the field appears very crowded in the GSC2; however, finding charts made using 2MASS images show that there are no bright close companions. The BOT assumes that 12520( 2) - 28-Jun-2011 10:36:01 - [ 4] most of these targets are unreddened O stars rather than the moderately reddened B stars that they are and so produces spurious warnings. The BOT also warns of a few unknown objects that might be in the BOA aperture, but as noted above these are too faint to be of concern. ------------------------------------------------------------------------------------ 12520( 2) -
