The GALAH Survey: Chemically tagging the Fimbulthul stream to the globular cluster Centauri
Jeffrey D. Simpson, Sarah L. Martell, Gary Da Costa +17
Using kinematics from Gaia and the large elemental abundance space of the second data release of the GALAH survey, we identify two new members of the Fimbulthul stellar stream, and…
The survey of Planetary Nebulae in Andromeda (M31) II. Age-velocity dispersion relation in the disc from Planetary Nebulae
Souradeep Bhattacharya, Magda Arnaboldi, Nelson Caldwell +7
The age-velocity dispersion relation is an important tool to understand the evolution of the disc of the Andromeda galaxy (M31) in comparison with the Milky Way. We use Planetary N…
Single-lined Spectroscopic Binary Star Candidates from a Combination of the RAVE and Gaia DR2 surveys
Danijela Birko, Tomaž Zwitter, Eva K. Grebel +11
The combination of the final version of the RAVE spectroscopic survey data release 6 with radial velocities and astrometry from Gaia DR2 allows us to identify and create a catalog…
The K2-HERMES Survey: Age and Metallicity of the Thick Disc
Sanjib Sharma, Dennis Stello, Joss Bland-Hawthorn +34
Asteroseismology is a promising tool to study Galactic structure and evolution because it can probe the ages of stars. Earlier attempts comparing seismic data from the {\it Kepler}…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
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…
