15 Giant Planet Orbiting Dead Dwarf Star

• Astronomers from the University of Warwick’s Department of Physics and the Millennium Nucleus for Planet Formation (NPF) at the University of Valparaiso have discovered a giant planet orbiting around a dead white dwarf star.
• The planet has been found in the form of a disc of gas formed from its evaporating atmosphere.
• The planet is Neptune-like and orbits a star four times its size once in ten days and leaves a comet-like tail of gas comprising hydrogen, oxygen and sulphur after its action.
• The discovery is the first ever of its kind and suggests that there could be more planets orbiting around dwarf stars yet to be discovered.
• The star WDJ0914+1914 was recognised in a study of ten thousand white dwarfs observed by the Sloan Digital Sky Survey.
• Till now there is no such evidence that any planet has withstood a star’s transition to a white dwarf.
• The discovery was published in the journal Nature.
