Stellar yields and chemical evolution - The solar neighborhood as a calibrator
Daniel Thomas, Laura Greggio, Ralf Bender
Uncertainties in stellar nucleosynthesis and their impact on models of chemical evolution are discussed. Comparing the Type II supernova nucleosynthesis prescriptions from Woosley…
Probing early-type galaxy evolution with the Kormendy relation
B. L. Ziegler, R. P. Saglia, R. Bender +3
We investigate the evolution of early-type galaxies in four clusters at z=0.4 (Abell370, Cl0303+17, Cl0939+47 and Cl1447+26) and in one at z=0.55 (Cl0016+16). The galaxies are sele…
Central UV Spikes in two Galactic Spheroids
Michele Cappellari, Francesco Bertola, David Burstein +3
FOS spectra and FOC photometry of two centrally located, UV-bright spikes in the elliptical galaxy NGC 4552 and the bulge-dominated early spiral NGC 2681, are presented. These spec…
