On the seismic modelling of subgiant stars: testing different grid interpolation methods
Miguel Clara, Margarida S. Cunha, Pedro P. Avelino +3
Context. The emergence of mixed modes during the subgiant phase, whose frequencies are characterized by a fast evolution with age, can potentially enable a precise determination of…
Buoyancy glitches in pulsating stars revisited
Margarida S. Cunha, Yuri C. Damasceno, Juliana Amaral +3
Sharp structural variations induce specific signatures on stellar pulsations that can be studied to infer localised information on the stratification of the star. This information…
Evidence of structural discontinuities in the inner core of red-giant stars
Mathieu Vrard, Margarida S. Cunha, Diego Bossini +3
Red giants are stars in the late stages of stellar evolution. Because they have exhausted the supply of hydrogen in their core, they burn the hydrogen in the surrounding shell. Onc…
The influence of metallicity on stellar differential rotation and magnetic activity
Christoffer Karoff, Travis S. Metcalfe, Angela R. G. Santos +20
Observations of Sun-like stars over the last half-century have improved our understanding of how magnetic dynamos, like that responsible for the 11-year solar cycle, change with ro…
