The GALAH+ Survey: A New Library of Observed Stellar Spectra Improves Radial Velocities and Hints at Motions within M67
Tomaž Zwitter, Janez Kos, Sven Buder +25
GALAH+ is a magnitude-limited survey of high resolution stellar spectra obtained by the HERMES spectrograph at the Australian Astronomical Observatory. Its third data release provi…
The GALAH Survey: Dependence of elemental abundances on age and metallicity for stars in the Galactic disc
Sanjib Sharma, Michael R. Hayden, Joss Bland-Hawthorn +24
Using data from the GALAH survey, we explore the dependence of elemental abundances on stellar age and metallicity among Galactic disc stars. We find that the abundance of most ele…
The GALAH Survey: Chemical Clocks
Michael R. Hayden, Sanjib Sharma, Joss Bland-Hawthorn +27
Previous studies have found that the elemental abundances of a star correlate directly with its age and metallicity. Using this knowledge, we derive ages for a sample of 250,000 st…
Combined APOGEE-GALAH stellar catalogues using the Cannon
Govind Nandakumar, Michael R. Hayden, Sanjib Sharma +21
APOGEE and GALAH are two high resolution multi-object spectroscopic surveys that provide fundamental stellar parameters and multiple elemental abundance estimates for about half a…
The GALAH survey: tracing the Galactic disk with Open Clusters
Lorenzo Spina, Yuan-Sen Ting, Gayandhi M. De Silva +28
Open clusters are unique tracers of the history of our own Galaxy's disk. According to our membership analysis based on \textit{Gaia} astrometry, out of the 226 potential clusters…
The GALAH survey: effective temperature calibration from the InfraRed Flux Method in the Gaia system
L. Casagrande, J. Lin, A. D. Rains +23
In order to accurately determine stellar properties, knowledge of the effective temperature of stars is vital. We implement Gaia and 2MASS photometry in the InfraRed Flux Method an…
