(Phys.org) —A pair of astronomers with the University of California has demonstrated via computer simulation that the reason some hot or warm Jupiter exoplanets orbit their star so closely is because they are pulled there ...
(PhysOrg.com) -- Astronomers once thought that the process of star formation was more-or-less controlled by the simple coalescence of material by gravity, leading eventually to a new star. But they have come to realize that ...
