Large-scale time-series spectroscopy for stellar ages
David Gruner, Sydney A. Barnes, Ansgar Reiners +16
To date, Galactic Astronomy has largely concerned itself with astrophysical processes, and with the locations, space motions and compositions of objects. Consider, for example, the…

Surface image and activity-corrected orbit of the RS CVn binary HR 7275: Disentangling activity tracers
Ã. Adebali, M. Weber, K. G. Strassmeier +3
Quantifying stellar parameters and magnetic activity for cool stars in double-lined spectroscopic binaries (SB2) is not straightforward, as both stars contribute to the observed co…

First Doppler image and starspot-corrected orbit for Andromedae: A multifaceted activity analysis
Ã. Adebali, K. G. Strassmeier, I. V. Ilyin +3
We quantify the effect of starspots for the orbital elements of the spotted RS CVn binary Andromedae ( And) and present an empirical correction. The aim is to obtain a mor…
