Any star more than about 8 solar masses is a core collapse supernova candidate - which is basically the mechansim necessary to generate a neutron star. Fortunately, no stars in the 8+ solar mass range are located anywhere near earth. Sirius A is probably our most massive nearby star and weighs in at just over 2 solar masses. So, earth appears does not appear to be at risk of being ravaged by a core collapse supernova.
What a nice coincidence...:-)
