u in the 2HDM type III
We consider the Two Higgs Doublet Model (2HDM) of type III which leads to Flavour Changing Neutral Currents (FCNC) at tree level. In the framework of this model...
B-supergiants in IC1613: testing low-Z massive star physics and evolution
The physical processes taking place in massive stars during their life and death are highly dependent on the metallicity (Z) of their parent cloud. Observations...
We present the spatial distribution of chemical species in M 31, as derived from intermediate resolution spectra of seven B-type supergiants, lying within four...
Table 4 contains the adopted atomic data, equivalent widths and abundance estimates for all the metal lines observed in the SMC supergiants. It also contains...
The luminosity of the bulge was an important parameter in the early classification of galaxies. Later a large dispersion was found between the bulge-to-total (B...
