Stellar features in integrated starburst spectra as stellar population diagnostics
Daniel Schaerer
We review the main stellar features observed in starburst spectra from the UV to the near-IR and their use as fundamental tools to determine the properties of stellar populations f…
Gamma-ray line emission from OB associations and young open clusters: I. Evolutionary synthesis models
M. Cervino, J. Knodlseder, D. Schaerer +2
We have developed a new diagnostic tool for the study of gamma-ray emission lines from radioactive isotopes (such as 26Al and 60Fe in conjunction with other multi-wavelength observ…
Massive star populations and the IMF in metal-rich starbursts
Daniel Schaerer, Natalia G. Guseva, Yuri I. Izotov +1
We present new spectroscopic observations of Mkn 309, a starburst galaxy with one of the largest WR populations known. A highly super solar metallicity is derived. Using additional…
Massive Star Forming Regions: from diagnostic tools to derived properties
Daniel Schaerer
The current state-of-the-art of multi-wavelength diagnostic tools (evolutionary synthesis, photoionisation models) for massive star forming regions (HII regions, starbursts, etc.)…
Super star clusters as probes of massive star evolution and the IMF at extreme metallicities
Daniel Schaerer, Natalia G. Guseva, Yuri I. Izotov
Young super star clusters and young compact massive star forming regions can provide useful information on their burst properties (age, burst duration, SFR), the upper end of the I…
