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: 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…
An optimised tiling pattern for multi-object spectroscopic surveys: application to the 4MOST survey
E. Tempel, T. Tuvikene, M. M. Muru +22
Large multi-object spectroscopic surveys require automated algorithms to optimise their observing strategy. One of the most ambitious upcoming spectroscopic surveys is the 4MOST su…
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: Characterization of emission-line stars with spectral modelling using autoencoders
Klemen Čotar, Tomaž Zwitter, Gregor Traven +11
We present a neural network autoencoder structure that is able to extract essential latent spectral features from observed spectra and then reconstruct a spectrum from those featur…
