A paper published in Nature in September 2016 reports this in not a Delta-Scuti Star but is a unique White Dwarf / Cool Star Binary with an orbital period of 3.56 Hours and pulsations of 1.97 Minutes.
Details at http://www.nature.com/nature/journal/v537/n7620/full/nature18620.html there is also an article in the January 2017 Sky & Telescope about the Pro-Am (or more accurately Am-Pro)identification of the correct nature of this star.
Star type needs changing but as this appears to be a 'one off' I am not clear to what.
