The magnetic system SMSS J1606-1000 as a period bouncer
Adela Kawka, Stephane Vennes, Lilia Ferrario +7
We report the discovery of a rare close binary system, SMSS J160639.78-100010.7, comprised of a magnetic white dwarf with a field of about 30 MG and a brown dwarf. We measured an o…
Keck HIRES Spectroscopy of SkyMapper Commissioning Survey Candidate Extremely Metal-Poor Stars
A. F. Marino, G. S. Da Costa, A. R. Casey +11
We present results from the analysis of high-resolution spectra obtained with the Keck HIRES spectrograph for a sample of 17 candidate extremely metal-poor (EMP) stars originally s…
Galactic Archeology with the AEGIS Survey: The Evolution of Carbon and Iron in the Galactic Halo
Jinmi Yoon, Timothy C. Beers, Sarah Dietz +6
Understanding the evolution of carbon and iron in the Milky Way's halo is of importance because these two elements play crucial roles constraining star formation, Galactic assembly…
The EMBLA Survey -- Metal-poor stars in the Galactic bulge
Louise M. Howes, Martin Asplund, Stefan C. Keller +14
Cosmological models predict the oldest stars in the Galaxy should be found closest to the centre of the potential well, in the bulge. The EMBLA Survey successfully searched for the…
Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
L. M. Howes, A. R. Casey, M. Asplund +22
The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars…
First Light Results from the Hermes Spectrograph at the AAT
Andrew Sheinis, Borja Anguiano, Martin Asplund +60
The High Efficiency and Resolution Multi Element Spectrograph, HERMES, is a facility-class optical spectrograph for the Anglo-Australian Telescope (AAT). It is designed primarily f…
