The lowest detected stellar Fe abundance: The halo star SMSS J160540.18-144323.1
T. Nordlander, M. S. Bessell, G. S. Da Costa +12
We report the discovery of SMSS J160540.18-144323.1, a new ultra-metal poor halo star discovered with the SkyMapper telescope. We measure [Fe/H] = -6.2 +- 0.2 (1D LTE), the lowest…

New low-mass members of the Octans stellar association and an updated 30-40 Myr lithium age
Simon J. Murphy, Warrick A. Lawson
The Octans association is one of several young stellar moving groups recently discovered in the Solar neighbourhood, and hence a valuable laboratory for studies of stellar, circums…
