A Self-Consistent 3D Hydrodynamic Model for Helium Transit Signatures in Evaporating Hot Jupiters
Anselmo Falorca, Aline Vidotto
The HeI triplet line (1083 nm), together with hydrodynamic models, can be used to characterize atmospheric escape of exoplanets. However, most of the available models cannot captur…

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…

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…
