ULLYSES is a Director's Discretionary program to create a UV spectroscopic archive of young high- and low-mass stars in the local universe.

Overview

The Hubble UV Legacy Library of Young Stars as Essential Standards ("ULLYSES") is a Director's Discretionary program devoting ~1,000 HST orbits to the production of an ultraviolet spectroscopic library of young high- and low-mass stars in the local universe. The ULLYSES program uniformly samples the fundamental astrophysical parameter space for each mass regime -- including spectral type, luminosity class, and metallicity for massive OB stars (in the Magellanic Clouds and two other lower-metallicity nearby galaxies) and the mass, and disk accretion rate for low-mass T Tauri stars (in eight young Galactic star forming regions). The data will be gathered over a three-year period, from Cycle 27 through Cycle 29 (2020-2022). The data products are combined from individual, extracted and calibrated spectra obtained with the COS and STIS instruments on-board HST. Products are made using both archival HST data and new HST observations obtained through the ULLYSES program.

In addition to the MAST HLSP webpage here, you can read more about ULLYSES on their team page: https://ullyses.stsci.edu/index.html.  You can find out detailed information on the observations, the data processing, and access their spectral table.

Data Release 1 (05 Nov. 2020)

The first data release consists of multiple spectra for 115 massive stars in the Large and Small Magellanic Clouds. 43 of these 115 stars were recently observed with COS and STIS as part of the ULLYSES program; 8 of these 43 also have archival COS and STIS data. The remaining 72 targets have full UV coverage from archival programs (see the ULLYSES target lists for the LMC and SMC).

Data Products

For a full description of how the HLSPs were created, please see the Data Description page on the ULLYSES website.

The spectra have the following file naming convention:

hlsp_ullyses_hst_<instrument>_<target>_<opt-elem>_<product-type>_<version>.fits

where:

  • <instrument> = one or more values representing the instrument(s) used to create the spectrum, described more below
  • <target> = the name of a star in the ULLYSES program, all lowercase and no underscores allowed
  • <opt-elem> = one or more optical elements representing the grism(s) used to create the spectrum, described more below
  • <product-type> = the type of spectral product, described more in the table below
  • <version> = the data release identifier, e.g., "dr1", "dr2", etc.
