The GALAH Survey: Accreted stars also inhabit the Spite Plateau

Jeffrey D. Simpson, Sarah L. Martell, Sven Buder +22

The ESA Gaia astrometric mission has enabled the remarkable discovery that a large fraction of the stars near the Solar neighbourhood appear to be debris from a single in-falling s…

The GALAH+ Survey: Third Data Release

Sven Buder, Sanjib Sharma, Janez Kos +44

The ensemble of chemical element abundance measurements for stars, along with precision distances and orbit properties, provides high-dimensional data to study the evolution of the…

The GALAH Survey: Chemically tagging the Fimbulthul stream to the globular cluster Centauri

Jeffrey D. Simpson, Sarah L. Martell, Gary Da Costa +17

Using kinematics from Gaia and the large elemental abundance space of the second data release of the GALAH survey, we identify two new members of the Fimbulthul stellar stream, and…

The K2-HERMES Survey: Age and Metallicity of the Thick Disc

Sanjib Sharma, Dennis Stello, Joss Bland-Hawthorn +34

Asteroseismology is a promising tool to study Galactic structure and evolution because it can probe the ages of stars. Earlier attempts comparing seismic data from the {\it Kepler}…

The GALAH Survey and Gaia DR2: (Non)existence of five sparse high-latitude open clusters

Janez Kos, Gayandhi de Silva, Joss Bland-Hawthorn +21

Sparse open clusters can be found at high galactic latitudes where loosely populated clusters are more easily detected against the lower stellar background. Because most star forma…

The GALAH Survey: Stellar streams and how stellar velocity distributions vary with Galactic longitude, hemisphere and metallicity

Alice C. Quillen, Gayandhi De Silva, Sanjib Sharma +30

Using GALAH survey data of nearby stars, we look at how structure in the planar (u,v) velocity distribution depends on metallicity and on viewing direction within the Galaxy. In ne…
