Chemical composition and kinematics of ionised gas in low-mass star-forming galaxies with extremely high [OIII]/[OII] ratios
Y. I. Izotov, N. G. Guseva, D. Schaerer +1
We present Very Large Telescope/Xshooter spectrophotometric observations of eleven low-redshift (z<0.085) compact star-forming galaxies (`high O32 sample'). These galaxies are char…

Polytropic stellar wind models with strongly localized heating
L. Westrich, B. Shergelashvili, H. Fichtner +1
Polytropic models of stellar winds remain to be useful tools because they allow for a simple description of the energy balance of the expanding plasma without explicitly specifying…
