The GALAH Survey: Temporal Chemical Enrichment of the Galactic Disk
Jane Lin, Martin Asplund, Yuan-Sen Ting +22
We present isochrone ages and initial bulk metallicities (, by accounting for diffusion) of 163,722 stars from the GALAH Data Release 2, mainly composed of main…
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: Linking ridges, arches and vertical waves in the kinematics of the Milky Way
Shourya Khanna, Sanjib Sharma, Thor Tepper-Garcia +15
Gaia DR2 has revealed new small-scale and large-scale patterns in the phase-space distribution of stars in the Milky Way. In cylindrical Galactic coordinates , ridge-like…
The GALAH Survey: Chemodynamics of the Solar Neighbourhood
Michael R. Hayden, Joss Bland-Hawthorn, Sanjib Sharma +13
We present the chemodynamic structure of the solar neighbourhood using 62 814 stars within a 500 pc sphere of the Sun observed by GALAH and with astrometric parameters from Gaia DR…
