ULLYSES LMC

Large Magellanic Cloud OB Stars

Observations of the ULLYSES high-mass stars in the LMC 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/near-IR 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 LMC); 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".

Additional information — including targets with sufficient archival data — is available in the .csv file available for download here.
