Report submitted to Director, February 5, recommending the Hubble UV Legacy Library of Young Stars as Essential Standards, the ULLYSES project.
The full report will be made available after the Cycle 27 GO deadline.
Implementation
The program was announced to the community on March 4 2019. Neither the target list nor the detailed observing modes for ULLYSES have been defined as yet. STScI will constitute an implementation team to work with the community to refine those parameters. All observations will be non-proprietary and available immediately to the community.
We encourage the community to consider submitting Cycle 27 proposals to supplement and complement the conceptual program. Those proposals might include
- Pure parallel programs that take advantage of spectroscopic observations of OB stars in the Magellanic Clouds and/or low-mass T Tauri stars or brown dwarfs in young Galactic star-forming regions;
- Archival or Theory programs that can utilize or supplement the UV Legacy DD observations. We particularly encourage large-scale programs;
- GO/SNAP programs that can complement or supplement UV spectroscopic observations of young stars.
GO programs that are recommended for acceptance by the Cycle 27 TAC have priority over the UV Legacy DD program; TAC-approved observations will not be pre-empted by ULLYSES.
The final target list for ULLYSES will be announced in July and will take into account existing datasets, both archival and those that are part of ongoing GO programs.
