Analysis of 3D MHD Instability of Antisolar Latitudinal Differential Rotation in F, G and K stars
Analysis Instability Latitudinal Differential Rotation
2011/10/8
Motivated by observations that only a very few stars have been found to have antisolar differential rotation, much weaker in amplitude than that of the Sun, we analyze the stability of antisolar and s...
Chemical abundance analysis of the Open Clusters Berkeley 32, NGC 752, Hyades and Praesepe
Stars: abundances – Galaxy: disc – Galaxy: open clusters and associations: individual: NGC 752 Hyades Berkeley 32 Preasepe (M 44)
