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…
A thorough analysis of the short- and mid-term activity-related variations in the solar acoustic frequencies
A. R. G. Santos, M. S. Cunha, P. P. Avelino +2
The frequencies of the solar acoustic oscillations vary over the activity cycle. The variations in other activity proxies are found to be well correlated with the variations in the…
On the contribution of sunspots to the observed frequency shifts of solar acoustic modes
A. R. G. Santos, M. S. Cunha, P. P. Avelino +2
Activity-related variations in the solar oscillation properties have been known for 30 years. However, the relative importance of the different contributions to the observed variat…
Spin-orbit alignment of exoplanet systems: ensemble analysis using asteroseismology
T. L. Campante, M. N. Lund, J. S. Kuszlewicz +23
The angle between a planet's orbital axis and the spin axis of its parent star is an important diagnostic of planet formation, migration, and tidal evolution. We seek empirical…
