The ensemble of chemical element abundance measurements for stars, along with precision distances and orbit properties, provides high-dimensional data to study the evolution Milky Way. With this third release Galactic Archaeology HERMES (GALAH) survey, we publish 678 423 spectra 588 571 mostly nearby stars (81.2% are within <2 kpc), observed spectrograph at Anglo-Australian Telescope. This (hereafter GALAH+ DR3) includes all observations from GALAH Phase 1 (bright, main, faint 70%),...
We use more than 872,000 mid-to-high resolution (R $\sim$ 20,000) spectra of stars from the GALAH survey to discern diffuse interstellar bands (DIBs). four windows with wavelength range 4718 4903, 5649 5873, 6481 6739, and 7590 7890 \AA, giving a total coverage 967 \AA. produce $\sim$400,000 medium (ISM) absorption features correct them for radial velocities DIB clouds. Ultimately, we combine 33,115 best ISM into six reddening bins $0.1 \,\mathrm{mag} < E\mathrm{(B-V)} 0.7\, \mathrm{mag}$. A...
Abstract GALAH+ is a magnitude-limited survey of high resolution stellar spectra obtained by the HERMES spectrograph at Australian Astronomical Observatory. Its third data release provides reduced with new derivations parameters and abundances 30 chemical elements for 584,015 dwarfs giants, 88 per cent them in Gaia magnitude range 11 &lt; G 14. Here we use these improved values to build library observed which useful study variations individual spectral lines parameters. This other...
