Probing the Cores of Subdwarf B Stars: How do They Compare to Cores in Helium Core-Burning Red Giants?
Margarida S. Cunha, Juliana Amaral, Sofia Avelino +3
The mixing of material from stellar convective cores into their adjacent radiative layers has been a matter of long-standing debate. Pulsating subdwarf B stars offer excellent cond…
On the relation between activity-related frequency shifts and the sunspot distribution over the solar cycle 23
A. R. G. Santos, M. S. Cunha, P. P. Avelino +2
The activity-related variations in the solar acoustic frequencies have been known for 30 years. However, the importance of the different contributions is still not well established…
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…
