The current iteration of the RSG list is completed; future improvements are planned and will be added as soon as available. Other lists will also be uploaded for Wolf-Rayet and other stars soon.

Galactic RSG Candidates

Latest (April 11, 2024)

• RSG_and_close_stars_catalog_4_11_24.csv:
  • Final list containing both methods and a list of known RSG whose proximity prevents being in Gaia DR2/DR3 data printed in the recent paper (https://doi.org/10.48550/arXiv.2307.08785)
  • Includes adjustments based on work by Sebastián Otero
  • Details about the meaning of column identifiers can be found in the Column Descriptions folder under the same name
  • Utilizes AAVSO VSX version=7.32.4
  • Warning: two objects are included that only have positional information from Gaia DR2, and so columns like ra, dec, and radial velocity are left empty while ra_dr2, dec_dr2 .. etc have values (V1061 Sco and BD-17 5117)

Associated Lists (available in the data folder)

• RSG_catalog_4_11_24.csv:

  • Final list that does not include the close star list

• Bright_Late_Type_Star_Catalog:

  • Contains all late-type bright stars, used to produce Final_RSG_Catalog_8_10_2023
  • Contains stars that are not SN progenitors
  • Table 2 in the recent paper (https://doi.org/10.48550/arXiv.2307.08785)
  • Details about the meaning of column identifiers can be found in the Column Descriptions folder under the same name

  • First version of RSG candidate list used for SNEWS, includes an analysis on luminosity and the likelihood of being an RSG
  • Regions for the likelihood of RSG status include:
    • Gold - in an area of Luminosity/Effective Temperature space which should be almost complete RSGs
    • Silver - in an area of Luminosity/Effective Temperature space which has some AGB contamination
    • Bronze - in an area of Luminosity/Effective Temperature space with progressive more AGB contamination
