On the formation of molecules and solid-state compounds from the AGB to the PN phases
During the asymptoyic giant branch (AGB) phase, different elements are dredge- up to the stellar surface depending on progenitor mass and metallicity. When the...
On the Galactic globular cluster Delta VHBbump parameter .
We calculated new estimates of the Delta VHBbump parameter for 15 Galactic Globular Clusters (GGCs) using accurate ground-based photometric data. We enlarged...
The penumbra is ideally suited to challenge our understanding of magnetohydrodynamics. The energy transport takes place as magnetoconvection in inclined...
