The GALAH Survey: Using Galactic Archaeology to Refine our Knowledge of TESS Target Stars
Jake T. Clark, Mathieu Clerte, Natalie R. Hinkel +29
An unprecedented number of exoplanets are being discovered by the Transiting Exoplanet Survey Satellite (TESS). Determining the orbital parameters of these exoplanets, and especial…
HERBS II: Detailed chemical compositions of Galactic bulge stars
L. Duong, M. Asplund, D. M. Nataf +2
This work explores the detailed chemistry of the Milky Way bulge using the HERMES spectrograph on the Anglo-Australian Telescope. Here we present the abundance ratios of 13 element…
HERBS I: Metallicity and alpha enhancement along the Galactic bulge minor axis
L. Duong, M. Asplund, D. M. Nataf +3
To better understand the origin and evolution of the Milky Way bulge, we have conducted a survey of bulge red giant branch and clump stars using the HERMES spectrograph on the Angl…
The GALAH survey and Gaia DR2: dissecting the stellar disc's phase space by age, action, chemistry and location
Joss Bland-Hawthorn, Sanjib Sharma, Thor Tepper-Garcia +24
We use the second data releases of the ESA Gaia astrometric survey and the high-resolution GALAH spectroscopic survey to analyse the structure of our Galaxy's disc components. With…
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 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: 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…
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: 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…
The GALAH survey: An abundance, age, and kinematic inventory of the solar neighbourhood made with TGAS
S. Buder, K. Lind, M. K. Ness +31
The overlap between the spectroscopic Galactic Archaeology with HERMES (GALAH) survey & provides a high-dimensional chemodynamical space of unprecedented size. We present a…
The GALAH survey: properties of the Galactic disk(s) in the solar neighbourhood
L. Duong, K. C. Freeman, M. Asplund +26
Using data from the GALAH pilot survey, we determine properties of the Galactic thin and thick disks near the solar neighbourhood. The data cover a small range of Galactocentric ra…
The K2-HERMES Survey. I. Planet Candidate Properties from K2 Campaigns 1-3
Robert A. Wittenmyer, Sanjib Sharma, Dennis Stello +31
Accurate and precise radius estimates of transiting exoplanets are critical for understanding their compositions and formation mechanisms. To know the planet, we must know the host…
The GALAH survey: Chemical Tagging of Star Clusters and New Members in the Pleiades
Janez Kos, Joss Bland-Hawthorn, Ken Freeman +25
The technique of chemical tagging uses the elemental abundances of stellar atmospheres to `reconstruct' chemically homogeneous star clusters that have long since dispersed. The GAL…
The TESS-HERMES survey Data Release 1: high-resolution spectroscopy of the TESS southern continuous viewing zone
Sanjib Sharma, Dennis Stello, Sven Buder +22
The Transiting Exoplanet Survey Satellite (TESS) will provide high precision time-series photometry for millions of stars with at least a half-hour cadence. Of particular interest…
The Galah Survey: Classification and diagnostics with t-SNE reduction of spectral information
