The Evolution of Massive Stars: The Influence of Initial Composition and Mass Loss
… in the initial metal content relative to solar abundances is to cause the models to be bluer and, in general, slightly more luminous at comparable stages of evolution. In the absence of mass loss, models with M(,i) (LESSTHEQ) 30 M(,(CIRCLE)) and Z < 0.001 do not become red supergiants …

Neutron induced reactions on 26Al, 36Cl and 41Ca and their astrophysical implications
… the understanding of the observed 36S and 26Al solar abundances. In the case of 26Al, the 26Al(n,alpha)23Na cross section up to 45 keV has been determined. Six resonances are observed. For three of them, the total level width and the spin could be calculated. For most of the resonances the …

New Avenues in Atmospheric Modelling of Exoplanets
… lead to strong thermal inversions even with sub-solar abundances of these visible absorbers due to the change in infrared opacity. As a demonstration of this work I have shown that the thermal inversion on WASP-121b can be explained by all the visible absorbers listed above. These thermal …
