The GALAH Survey: Non-LTE departure coefficients for large spectroscopic surveys
A. M. Amarsi, K. Lind, Y. Osorio +23
Massive sets of stellar spectroscopic observations are rapidly becoming available and these can be used to determine the chemical composition and evolution of the Galaxy with unpre…
Optimal extraction of echelle spectra: getting the most from observations
Nikolai Piskunov, Ansgar Wehrhahn, Thomas Marquart
The price of instruments and observing time on modern telescopes is quickly increasing with the size of the primary mirror. Therefore, it is worth revisiting the data reduction alg…
Hidden magnetic fields of young suns
O. Kochukhov, T. Hackman, J. J. Lehtinen +1
Global magnetic fields of active solar-like stars are nowadays routinely detected with spectropolarimetric measurements and are mapped with Zeeman-Doppler imaging (ZDI). However, d…
SETI with Gaia: The observational signatures of nearly complete Dyson spheres
Erik Zackrisson, Andreas J. Korn, Ansgar Wehrhahn +1
A star enshrouded in a Dyson sphere with high covering fraction may manifest itself as an optically subluminous object with a spectrophotometric distance estimate significantly in…
