Williams University of Washington N ------------------------------------------------------------------------------------ Abstract Theoretical models of Asymptotic Giant Branch (AGB) stellar evolution rely on observations of the ratio of carbon-rich (C) to oxygen-rich (M) stars and the carbon star luminosity function (CSLF). Sensitivity and resolution limitations have restricted measurements of C/M and the CSLF to metal-poor environments in nearby galaxies. Unfortunately, while HST WFC3/IR broad-band imaging can detect AGB stars in more distant, metal-rich galaxies, it is impossible to distinguish between different AGB subtypes with only the available broad-band filters. However, our successful Cycle 20 1-orbit pilot program showed that AGB stars can be effectively separated into C and M stars using the WFC3/IR medium-band filters. Thus, detailed studies of AGB stellar evolution are now possible in galaxies that are only resolvable with HST. We propose to use the WFC3/IR medium-band filters to make the very first bias-free measurement of C/M and the CSLF in a metal-rich environment (M31). Our high-precision measurement of the morphology of the CSLF will calibrate the efficiency of the third dredge up and the minimum core mass to form a C star, both of which depend on the metallicity. Our measurements of the C/M ratio will leverage M31's metallicity distribution to determine the metallicity limit above which C stars cannot form. The interpretation of these observations is straightforward owing to the ability to leverage data products from the Panchromatic Andromeda Treasury (PHAT) program. As a result, we can conclusively evaluate AGB evolution models in a never-before-tested, metal-rich environment. ------------------------------------------------------------------------------------ 14072( 2) - 23-Jul-2015 18:27:26 - [ 2] Observations Description ------------------------ Targets: We will target 20 primary and 20 parallel fields in M31. All primary fields show evidence for star formation in the last 400 Myr, indicating the presence of an AGB star population at the appropriate age for C stars. Some target fields also contain spectroscopically-confirmed C stars. Parallel fields maximize coverage of star-forming regions. Filters: To take full advantage of the molecular features in near-IR spectra of C-rich stars from 0.9 to 1.7 microns, we require observations with F127M, F139M, and F153M. All three filters are necessary, since combinations with the broad-band optical and near-IR filters do not successfully isolate the carbon stars. Combined with the broad-band WFC3/IR and the optical photometry from PHAT, we will have well-sampled spectral coverage down to 2700 angstroms. The ACS parallels will use F625W and F658N to identify emission line stars. Required primary exposure times and photometric depth: In order to detect all AGB stars, we must achieve full photometric completeness at the tip of the red giant branch (TRGB). Assuming a typical orbit time of ~57 min for M31, we can achieve the necessary photometric depth within a single orbit (as demonstrated in our pilot program). After accounting for overheads, this allows for total exposure times of about 800-900 s in each filter, resulting in S/N > 7.3 in F139M (optimal S/N > 9.2) for m_F160W = 23 mag, using a Bruzual template for an M6III star. The S/N is even better in the F127M and F153M filters, owing to a higher throughput. For reference, the TRGB in the F160W filter corresponds to ~19 mag at the distance of M31. For the parallels, we maximize the exposure time in F658N, while also preserving image quality and avoiding buffer dump latency. The remainging available parallel time is filled with F625W for continuum subtraction. Dithering Strategy for primaries: Dithering diminishes errors associated with where a source is placed on a pixel, undersampling of the WFC3/IR channel, and image artifacts such as cosmic rays. We choose a 4-pt dither pattern to acheive Nyquist sampling of the PSF in F127M. The remaining 2 filters will use a 2-pt dither: we will reduce F127M simultaneously to acheive Nyquist sampling for the 2-pt dithers (e.g., PHAT; Dalcanton et al. 2012). We choose this strategy to allow for ACS buffer dumps in parallel. The dither patterns are entered manually in the position offsets, following the WFC3-IR-DITHER-BOX-MIN pattern values listed in the WFC3 handbook in Table C.3. For the parallels, each filter is imaged in two of the dither positions. The PHAT data is Nyquist sampled in F814W, and we will re-reduce that data simultaneously to achieve Nyquist sampling in F625W and F658N. Avoiding Saturation: Saturation is mitigated by always having at least one short exposure per field/filter, and by the sampling of WFC3/IR. The parallel fields are not in danger of saturation: the F625W filter includes one short exposure (100s), and the width of F658N is narrow enough to allow for long exposures. Parallels: We are observing with ACS in parallel. Orientation constraints 14072( 2) - 23-Jul-2015 18:27:26 - [ 3] ensure that the parallel fields maximize coverage of star-forming regions and to ensure that the fields fall inside the PHAT coverage. ------------------------------------------------------------------------------------ 14072( 2) - 23-Jul-2015 18:27:26 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 M31-POS01 GALAXY, DISK, SPIRAL RA=00H43M18.4860S +/- 0.1", J2000 V = 18 +/- 0.5 DEC=+41D26'10.93" +/- 0.1" Reference Frame: ICRS Comments: This is a star field, with a wide range of V-mags.
