The GALAH Survey: Lithium-strong KM dwarfs
M. Žerjal, M. J. Ireland, T. Nordlander +8
Identifying and characterizing young stars in the Solar neighbourhood is essential to find and describe planets in the early stages of their evolution. This work seeks to identify…
SkyMapper stellar parameters for Galactic Archaeology on a grand-scale
L. Casagrande, C. Wolf, A. D. Mackey +3
The SkyMapper photometric surveys provides uvgriz photometry for several millions sources in the Southern sky. We use DR1.1 to explore the quality of its photometry, and develop a…
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: a catalogue of carbon-enhanced stars and CEMP candidates
Klemen Čotar, Tomaž Zwitter, Janez Kos +19
Swan bands - characteristic molecular absorption features of the C molecule - are a spectroscopic signature of carbon-enhanced stars. They can also be used to identify carbon-e…
The GALAH and TESS-HERMES surveys: high-resolution spectroscopy of luminous supergiants in the Magellanic Clouds and Bridge
Jeffrey D. Simpson, Dennis Stello, Sanjib Sharma +24
We report the serendipitous observations of 571 luminous supergiants in the Magellanic Clouds by the spectroscopic GALAH and TESS-HERMES surveys: 434 stars in the Large Magellanic…
The GALAH Survey: Second Data Release
S. Buder, M. Asplund, L. Duong +39
The Galactic Archaeology with HERMES (GALAH) survey is a large-scale stellar spectroscopic survey of the Milky Way and designed to deliver chemical information complementary to a l…
The GALAH Survey: Velocity fluctuations in the Milky Way using red clump giants
Shourya Khanna, Sanjib Sharma, Joss Bland-Hawthorn +20
If the Galaxy is axisymmetric and in dynamical equilibrium, we expect negligible fluctuations in the residual line-of-sight velocity field. Recent results using the \apg{} survey f…
The GALAH Survey: Verifying abundance trends in the open cluster M67 using non-LTE spectroscopy
Xudong Gao, Karin Lind, Anish M. Amarsi +28
Open cluster members are coeval and share the same initial bulk chemical compositions. Consequently, differences in surface abundances between members of a cluster that are at diff…
The GALAH Survey: Accurate Radial Velocities and Library of Observed Stellar Template Spectra
Tomaž Zwitter, Janez Kos, Andrea Chiavassa +34
GALAH is a large-scale magnitude-limited southern stellar spectroscopic survey. Its second data release (GALAH DR2) provides values of stellar parameters and abundances of 23 eleme…
The GALAH survey: Co-orbiting stars and chemical tagging
Jeffrey D. Simpson, Sarah L. Martell, Gary Da Costa +24
We present a study using the second data release of the GALAH survey of stellar parameters and elemental abundances of 15 pairs of stars identified by Oh et al 2017. They identifie…
Accurate effective temperatures of the metal-poor benchmark stars HD 140283, HD 122563 and HD 103095 from CHARA interferometry
I. Karovicova, T. R. White, T. Nordlander +14
Large stellar surveys of the Milky Way require validation with reference to a set of "benchmark" stars whose fundamental properties are well-determined. For metal-poor benchmark st…
