An international group of astronomers, including Dr Simon Jeffery of the Armagh Observatory, has used the Hubble Space Telescope to verify the origin of a very unusual and rare type of star. The group's studies confirm that the so-called "extreme helium stars" are formed by the merger of two white dwarf stars. ... One, dubbed the final-flash (FF) model, suggests an outer helium layer of a cooling white dwarf ignites, producing an extra thermal pulse that balloons the star into a giant. ...
