To probe this requires accurate neutron star radii and masses. We recently showed that broad iron lines in neutron star low-mass X-ray binaries (LMXBs) constrain the neutron star radius. LMXBs also provide us with another tool, kHz quasi-periodic oscillations (QPOs). Combining the inner disk velocity (from modeling the iron line) and the frequency of the kHz QPOs gives a method to measure the neutron star mass. We propose a 100 ks observation of Cyg X-2 with Suzaku to provide a detailed iron line profile. Combined with simultaneous observations with RXTE to determine the kHz QPO frequency, we will measure the neutron star mass. Cyg X-2 is the perfect test case as it already has a known mass from optical observations. | GALACTIC POINT SOURCES | 4 | B | EDWARD CACKETT | USA | 3 | AO3 | MEASURING NEUTRON STAR MASSES USING BROAD IRON LINES AND KHZ QPOS | XIS | Y | https://data.darts.isas.jaxa.jp/pub/suzaku/ver3.0/403063010/ | Quick Look |
