Abstract

We continue former work on the modeling of potential effects of Gamma Ray Bursts on Phanerozoic Earth. We focus on global biospheric effects of ozone depletion and model the spectral reduction of light by NO2 formed in the stratosphere. We also illustrate the current complexities involved in the prediction of how terrestrial ecosystems would respond to this kind of burst. We conclude that more biological field and laboratory data are needed to reach even moderate accuracy in this modeling.

Surman 2006 喷流中的核合成 2

主要内容:
伽玛暴喷流中也可以发生核合成, 根据吸积率不同, 产物及丰度也不一样。 (高的10M_sun s^-1也是可能的)
