Astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP), present for the first time a movie that shows the evolution of stellar spots on a star other than our Sun. The long-term, highly-sampled, phase-resolved spectroscopic data were made possible with the STELLA robotic telescopes on Tenerife. Over a period of 6 years the growth and fade of giant stellar spots on the star XX Tri are seen. The spots reveal an underlying magnetic cycle that has a period comparable to our Sun’s but is much stronger. googletag.cmd.push(function() { googletag.display(‘div-gpt-ad-1449240174198-2′); }); Generally, it is not possible to resolve stellar surfaces other than our Sun’s directly. Clever mathematical methods and observing techniques were introduced to resolve stellar surfaces indirectly. This technique, commonly referred to as Doppler imaging or Doppler tomography, became the most advanced tool for the study of stars. In order to not only image but also to reconstruct the evolution of star spots, well-sampled time series of high-resolution spectra are needed. To obtain one single image of the stellar surface, intrinsic variations confine the data gatheri...
