Astronomers using the United Kingdom Infrared Telescope (UKIRT) in Hawaii discovered the four star pairs, each of which is a binary system in which two stars circle each other in less than four hours.
Even though the suite of instruments for the E-ELT has yet to be finalized, ESO astronomer Joe Liske says the telescope will make observing time for cosmology, nearby galaxies, solar system studies and the burgeoning list of planets now known to circle other stars.
The Mirrlees review has some useful ideas on how to square the circle: indeed, perhaps its biggest message is that thinking holistically about the tax system helps resolve some of these conflicts.
