Abstract
Within a string cosmology context, the large-scale temperature anisotropies may arise from the contribution of seeds to the metric fluctuations. We st udy the cases or electromagnetic and axion seeds. We find that massless or very light axions can lead to a nat or slightly tilted blue spectrum that f its current data.
