DISCOVERY OF THE SPIN FREQUENCY OF 4U 0614+09 WITH THE SWIFT BURST ALERT TELESCOPE

摘要

We report the discovery of burst oscillations at 414.7 Hz during a thermonuclear X-ray burst from the low-mass X-ray binary (LMXB) 4U 0614+091 with the Burst Alert Telescope (BAT) on board Swift. In a search of the BAT archive, we found two burst triggers
