The GALAH survey: a catalogue of carbon-enhanced stars and CEMP candidates
Klemen Čotar, Tomaž Zwitter, Janez Kos +19
Swan bands - characteristic molecular absorption features of the C molecule - are a spectroscopic signature of carbon-enhanced stars. They can also be used to identify carbon-e…
Gaia Data Release 2. Summary of the contents and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +4
We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…
Gaia Data Release 2: Properties and validation of the radial velocities
D. Katz, P. Sartoretti, M. Cropper +51
For Gaia DR2 (GDR2), 280 million spectra, collected by the RVS instrument on-board Gaia, were processed and median radial velocities were derived for 9.8 million sources brighter t…
Gaia Data Release 2: Processing the spectroscopic data
P. Sartoretti, D. Katz, M. Cropper +50
The Gaia Data Release 2 contains the 1st release of radial velocities complementing the kinematic data of a sample of about 7 million relatively bright, late-type stars. Aims: This…
COBAIN: generalized 3D radiative transfer code for contact binary atmospheres
Angela Kochoska, Andrej Prša, Tomaž Zwitter +2
Contact binary stars have been known to have a peculiar and somewhat mysterious hydro- and thermodynamical structure since their discovery, which directly affects the radiation dis…
The GALAH and TESS-HERMES surveys: high-resolution spectroscopy of luminous supergiants in the Magellanic Clouds and Bridge
Jeffrey D. Simpson, Dennis Stello, Sanjib Sharma +24
We report the serendipitous observations of 571 luminous supergiants in the Magellanic Clouds by the spectroscopic GALAH and TESS-HERMES surveys: 434 stars in the Large Magellanic…
