The GALAH Survey: Improving our understanding of confirmed and candidate planetary systems with large stellar surveys
Jake T. Clark, Duncan J. Wright, Robert A. Wittenmyer +24
Pioneering photometric, astrometric, and spectroscopic surveys are helping exoplanetary scientists better constrain the fundamental properties of stars within our galaxy, and the p…
A barred Milky Way surrogate from an N-body simulation
T. Tepper-Garcia, J. Bland-Hawthorn, E. Vasiliev +10
We present an N-body model for the barred Milky Way (MW) galaxy that reproduces many of its properties, including the overall mass distribution, the disc kinematics, and the proper…
Reliable stellar abundances of individual stars with the MUSE integral-field spectrograph
Zixian Wang, Michael R. Hayden, Sanjib Sharma +4
We present a novel approach to deriving stellar labels for stars observed in MUSE fields making use of data-driven machine learning methods. Taking advantage of the comparable spec…
The GALAH Survey: Chemical tagging and chrono-chemodynamics of accreted halo stars with GALAH+ DR3 and eDR3
Sven Buder, Karin Lind, Melissa K. Ness +27
Since the advent of astrometry, it is possible to identify massive accreted systems within the Galaxy through their unique dynamical signatures. One such system, -Saus…
An [/Fe]-enhanced thick disk in a Milky Way Analogue
Nicholas Scott, Jesse van de Sande, Sanjib Sharma +5
The Milky Way disk consists of two prominent components - a thick, alpha-rich, low-metallicity component and a thin, metal-rich, low-alpha component. External galaxies have been sh…
The GALAH Survey: No chemical evidence of an extragalactic origin for the Nyx stream
Daniel B. Zucker, Jeffrey D. Simpson, Sarah L. Martell +20
The results from the ESA Gaia astrometric mission and deep photometric surveys have revolutionized our knowledge of the Milky Way. There are many ongoing efforts to search these da…
