Learning about the latitudinal distribution of starspots through the periodogram analysis of photometric data
A. R. G. Santos, M. S. Cunha, P. P. Avelino +2
Starspots are cooler and darker than the stellar surface. Therefore, the emitted flux of a star changes when spots are visible on its surface. The presence of spots together with t…
Starspot signature on the light curve: Learning about the latitudinal distribution of spots
A. R. G. Santos, M. S. Cunha, P. P. Avelino +2
Quasi-periodic modulations of the stellar light curve may result from dark spots crossing the visible stellar disc. Due to differential rotation, spots at different latitudes gener…
Probing seismic solar analogues through observations with the NASA Kepler space telescope and HERMES high-resolution spectrograph
P. G. Beck, D. Salabert, R. A. García +21
Stars similar to the Sun, known as solar analogues, provide an excellent opportunity to study the preceding and following evolutionary phases of our host star. The unprecedented qu…
