Merging high resolution spectroscopy with accurate photometry in the study of open clusters
Kevin Luke Beeson, Janez Kos
Doktorska disertacija
Oznake: stars;open clusters;photometry;spectroscopy;
The study of stars' chemical composition is pivotal for understanding the Milky Way's history. The explosion of large astronomical surveys in the 21$^{\rm{st}}$ century gives a wealth of data for astronomers to explore with the improving observational analytical methods. In this thesis, we combined ...

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 provides reduced spectra with new derivations of stellar parameters and abundances of 30 chemical elements for 584 015 dwarfs ...

We use more than 872 000 mid- to high-resolution (R ∼ 20 000) spectra of stars from the GALactic Archaeology with HERMES (GALAH) survey to discern the spectra of diffuse interstellar bands (DIBs). We use four windows with the wavelength ranges 4718–4903, 5649–5873, 6481–6739, and 7590–7890 Å, giving ...
