1. Dynamics and Atomic Processes in the Symbiotic Star AG Peg as Derived from Its Emission Line Spectrum
Sammanfattning : The spectra of symbiotic stars are shown to frequently contain numerous fluorescence lines caused by Photo-excitation by Accidental Resonance (PAR). So far, most work involving fluorescence in stellar spectra has been assigned to the search of new PAR mechanisms, which can explain the presence of certain emission lines. LÄS MER
2. Biomedical and atmospheric applications of optical spectroscopy in scattering media
Sammanfattning : Spectroscopic analysis of scattering media is difficult because the effective path length of the light is non-trivial to predict when photons are scattered many times. The main area of research for such conditions is biological tissues, which scatter light because of variations of the refractive index on the cellular level. LÄS MER
