Stars flying by each other might pose a great opportunity in search for advanced civilisations

New list of pairs of gravitationaly unbound stars in our neighborhood might present a new set of interesting targets for those who look for advanced civilisations. When two stars come close to each other, the advanced enough civilisation might take an advantage and migrate from one system to the other. In new study a list is presented of best candidate stars.
