- Reduced (non median-subtracted) JWST/MIRI Imager data of WR 140 used in Lau et al. (2022). MIRI Imager observations of WR140 were taken using the F770W, F1550W, and F2100W filters. See Methods section of the paper mentioned above for more details on the observations. NOTE: A simple sigma-clipped median subtraction that ignores pixel values of 0.0 was applied to this data before analysis in the paper (e.g. "sigma_clipped_stats([Imager Data], mask_value = 0.0)" using the astropy.stats package. Figures below show the median-subtracted images at each filter. Also note that emission from the core or WR 140 and some of the first dust shell were saturated in the Imager observations.
- Normalized, continuum subtracted, and smoothed 6 - 9 μm spectrum of the C1 feature in Shell 2 around WR 140 from MIRI/MRS observations used in Lau et al. (2022). This MIRI/MRS spectrum reveals the broad 6.4 and 7.7 μm features directly detected from the dust emission from the C1 feature in Shell 2 (blue circle) at the time of the observations. See the paper mentioned above for more details on the observations, data reduction, and interpretation.
- Geometric model code for dust-forming colliding-wind binaries developed by Han et al. (2022) and used in Lau et al. (2022) to model the circumstellar dust shells around WR 140. The code is written in matlab, and a python-based code is currently in development.
- 3D prints of circumstellar dust around WR 140 developed in collaboration with WR DustERS members Carol Christian (STScI) and Tom Madura (SJSU).
