The pair of stars orbit each other in approximately four hours and have a combined mass of 1.8 times the sun. Due to their relative closeness and mass researchers believe it is likely the pair will be drawn together before exploding into a supernova.<\/p>\n<p><a href=\"http:\/\/www.nature.com\/nature\/journal\/vaop\/ncurrent\/full\/nature14124.html\" target=\"_blank\"><span style=\"text-decoration: underline;\">Original research paper<\/span><\/a>\u00a0published in <em>Nature\u00a0<\/em>on\u00a0<strong>February 9<\/strong><span class=\"aBn\" tabindex=\"0\" data-term=\"goog_453723367\"><span class=\"aQJ\"><strong>, 2015<\/strong>.<\/span><\/span><\/p>\n<p><span style=\"text-decoration: underline;\"><em><strong>Names and affiliations of selected\u00a0authors<\/strong><\/em><\/span><\/p>\n<h4>M.
