TL;DR: In this article, the authors present the data reduction procedures being used by the GALactic Archeology with Hermes (GALAH) survey, carried out with the HERMES fiber-fed, multi-object spectrograph on the 3.9m Anglo-Australian Telescope.

TL;DR: In this paper, the authors used the second data releases of the European Space Agency Gaia astrometric survey and the high-resolution Galactic Archaeology with HERMES (GALAH) spectroscopic survey to analyse the structure of the ODE.

TL;DR: In this paper, the authors carried out an abundance analysis of seven elements (Li, O, Na, Mg, Al, Si, and Fe) in 66 stars belonging to the open cluster M67, based on high resolution GALAH spectra, 1D MARCS model atmospheres, and non-local thermodynamic equilibrium (non-LTE) radiative transfer.
Binary open clusters in the Milky Way: photometric and spectroscopic analysis of NGC 5617 and Trumpler 22

TL;DR: In this paper, the authors investigated the physical connection between the open clusters NGC 5617 and Trumpler 22 and reported their spatial proximity and common age of ~70 Myr based on new CCD photometry.
