ULLYSES SMC

Small Magellanic Cloud OB Stars

Observations of the ULLYSES high-mass stars in the SMC will be obtained during HST cycles 27-29 with COS/G130M/(1096,1291), COS/G160M/1611, COS/G185M/(1921,1953,1986), STIS/E140M/1425, and/or STIS/E230M/(1978,2707). The specific settings for each target will depend on the stellar type, the stellar fluxes, and the availability of suitable archival spectra. Optical/NIR spectra (e.g., from VLT/UVES or GIRAFFE) are available for many of the sight lines.

For each star, the table below gives the generally accepted target name (with a link to SIMBAD); the target names as they appear in the MAST archive, with the name adopted by the ULLYSES team in bold; the stellar position (generally from Gaia DR2 or 2MASS); the adopted spectral type, V magnitude, and total E(B-V) (i.e., Galactic plus SMC); and the v sin(i). Three additional columns will be populated (when the information exists), giving the proposal ID, the science configuration (indicating which instruments and channels will be used), the date of the first observation of that target, and the status of all observations for the target. Further information about each visit can be found by clicking on the row for the target of interest. An additional table will appear that will contain the visit ID, the scheduling status of that visit, a more detailed science configuration (including grating and central wavelength) and the observation date for each visit. In this additional table, any row that is highlighted in purple indicates the visit includes proprietary archival data which will not be included in the final ULLYSES data products until they are publicly available.

The "Overall Status" column shows the current observational status of a target. Targets with complete wavelength coverage are marked as "Completed". Targets with partial wavelength coverage and/or with currently scheduled observations are marked as "In Progress". Targets with no wavelength coverage and no currently scheduled observations are marked as "Not Yet Implemented".

CSV files with scientific metadata are also available for download. A CSV file with the complete sample of SMC targets can be downloaded here. A CSV file with a subset of targets, but which includes references for metadata, can be downloaded here. A corresponding HTML table, with hyperlinked references, can also be downloaded here.
