... Received; in original form ABSTRACT The main astrophysical factories of fluorine (19 F) are thought to be Type II supernovae, WolfґRayet stars, and the asymptotic giant branch (AGB) of intermediate mass stars. We present a model for the chemical evolution of fluorine in the Milky Way using a semi-analytic multi-zone chemical evolution model. ... 2003). ... Fluorine yields from a) SNe I I (Wo osley & Weaver 1995), b) WR (Meynet & Arnould 2000), and c) AGB stars (App endix). ... Figure 3. ...

... The modelling of the inflationary epoch using scalar fields is described, and then results giving the form of perturbations produced by inflation are quoted. ... This can be specified a by the energy density (t) and the pressure p(t). ... 5.5 A worked example: polynomial chaotic inflation The simplest inflation model 6 arises when one chooses a polynomial potential, such as that for a massive but otherwise non-interacting field, V () = m2 2 /2 where m is the mass of the scalar field. ...

A new luminosity model consistent with the COBE NIR data and the apparent magnitude distributions of bulge clump giant stars has bulge/bar length of 3.5 kp c, axis ratios of 1:(0.3-0.4):0.3, and short disk scale-length ( 2.1 kp c). ... From Bissantz & Gerhard (2002). that the line-of-sight distribution of luminosity in the bulge part correct. ...
