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…
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: 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: 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…
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: Chemical homogeneity of the Orion complex
Janez Kos, Joss Bland-Hawthorn, Sven Buder +17
Due to its proximity, the Orion star forming region is often used as a proxy to study processes related to star formation and to observe young stars in the environment they were bo…
The COMBS Survey -- II. Distinguishing the Metal-Poor Bulge from the Halo Interlopers
Madeline Lucey, Keith Hawkins, Melissa Ness +9
The metal-poor stars in the bulge are important relics of the Milky Way's formation history, as simulations predict that they are some of the oldest stars in the Galaxy. In order t…
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…
The halo of M105 and its group environment as traced by planetary nebula populations: I. Wide-field photometric survey of planetary nebulae in the Leo I group
J. Hartke, M. Arnaboldi, O. Gerhard +6
M105 (NGC 3379) is an early-type galaxy in the Leo I group. This group is the nearest group that contains all main galaxy types and can thus be used as a benchmark to study the pro…
The GALAH Survey: A new constraint on cosmological lithium and Galactic lithium evolution from warm dwarf stars
Xudong Gao, Karin Lind, Anish M. Amarsi +22
Lithium depletion and enrichment in the cosmos is not yet well understood. To help tighten constraints on stellar and Galactic evolution models, we present the largest high-resolut…
The GALAH survey: A census of lithium-rich giant stars
Sarah Martell, Jeffrey Simpson, Adithya Balasubramaniam +20
We investigate the properties of 1262 red giant stars with high photospheric abundances of lithium observed by the GALAH and \Ktwo-HERMES surveys, and discuss them in the context o…
A giant galaxy in the young Universe with a massive ring
Tiantian Yuan, Ahmed Elagali, Ivo Labbe +12
In the local (redshift z~0) Universe, collisional ring galaxies make up only ~0.01% of galaxies and are formed by head-on galactic collisions that trigger radially propagating dens…
K2-HERMES II. Planet-candidate properties from K2 Campaigns 1-13
Robert A. Wittenmyer, Jake T. Clark, Sanjib Sharma +22
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: Multiple stars and our Galaxy. I. A comprehensive method for deriving properties of FGK binary stars
G. Traven, S. Feltzing, T. Merle +24
Binary stellar systems form a large fraction of the Galaxy's stars. They are useful as laboratories for studying the physical processes taking place within stars, and must be corre…
Fundamental relations for the velocity dispersion of stars in the Milky Way
Sanjib Sharma, Michael R. Hayden, Joss Bland-Hawthorn +34
We explore the fundamental relations governing the radial and vertical velocity dispersions of stars in the Milky Way, from combined studies of complementary surveys including GALA…
The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- II: Stellar Atmospheric Parameters, Chemical Abundances and Distances
Matthias Steinmetz, Guillaume Guiglion, Paul J. McMillan +58
We present part 2 of the 6th and final Data Release (DR6 or FDR) of the Radial Velocity Experiment (RAVE), a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars rando…
The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- I: Survey Description, Spectra and Radial Velocities
Matthias Steinmetz, Gal Matijevic, Harry Enke +59
The Radial Velocity Experiment (RAVE) is a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars randomly selected in the southern hemisphere. The RAVE medium-resolutio…
