First Doppler image and starspot-corrected orbit for Andromedae: A multifaceted activity analysis
Ö. 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 more…
