(2007) [Journal article]Random diffusion is shown to be an important mechanism on fostering cooperative behavior among simple agents (memoryless, unconditional cooperators or defectors) living on a spatially structured environment. In particular, ... -
Evidence of thin helium envelopes in PG 1159 stars
(2008) [Journal article]We present evidence that PG 1159 stars could harbor He-rich envelopes substantially thinner than those predicted by current evolutionary models with current estimates of mass loss, which may be attributable to an extensive ... -
Solar wind strahl broadening by self-generated plasma waves
(2013) [Journal article]This Letter reports on the results of numerical simulations which may provide a possible explanation for the strahl broadening during quiet solar conditions. The relevant processes involved in the broadening are due to ...
