Discussion Overview

The discussion centers around the search for recent data on the abundances of elements in the Small Magellanic Cloud (SMC), focusing on metallicities and related research papers.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • One participant inquires about recent tables of elemental abundances in the SMC.
  • Another participant mentions that the metallicities in the SMC are low, approximately [Fe/H]~-0.6 dex, and notes the uncertainty in absolute abundances due to challenges in obtaining HI data.
  • A reference to a paper by Welty et al. (2001) is provided as a starting point for ISM abundances in the SMC.
  • A further suggestion is made to consult Venn (1999) for information on A-Type supergiant abundances in the SMC and related references.
  • One participant expresses gratitude for the information shared.

Areas of Agreement / Disagreement

Participants appear to agree on the low metallicities in the SMC and the usefulness of the referenced papers, but no consensus on a specific recent table of abundances is reached.

Contextual Notes

The discussion highlights uncertainties regarding absolute abundances and the challenges in obtaining certain data, which may affect the interpretation of results.

Who May Find This Useful

Researchers and enthusiasts interested in astrophysics, particularly those focusing on stellar abundances and the characteristics of the Small Magellanic Cloud.

Hi all,

Does anyone know if there is a recent table of the abundances of elements in the Small Magellanic Cloud.

Thanks all

The metallicities are fairly low, with [Fe/H]~-0.6 dex or so. The relative abundances in that paper are really good, the absolute ones are somewhat more uncertain as HI is hard to get. Start there, maybe check who has referenced it and go from there.. .

ISM abundances in the SMC from the HST
Welty et al., 2001, ApJ, 554, 75
 
See also Venn 1999, "A-Type Supergiant Abundances in the Small Magellanic Cloud: Probes of Evolution", references therein and citations to the paper.
 
THANK YOU! Very helpful
