Implications of kHz QPOs for the spin frequencies and magnetic fields of neutron stars: new results from Circinus X-1
Stratos Boutloukos, Frederick K. Lamb
Detection of paired kilohertz quasi-periodic oscillations (kHz QPOs) in the X-ray emission of a compact object is compelling evidence that the object is an accreting neutron star.…
Accreting Neutron Stars in Low-Mass X-Ray Binary Systems
Frederick K. Lamb, Stratos Boutloukos
Using the Rossi X-ray Timing Explorer (RossiXTE), astronomers have discovered that disk-accreting neutron stars with weak magnetic fields produce three distinct types of high-frequ…
kHz QPO pairs expose the neutron star of Circinus X-1
S. Boutloukos, M. van der Klis, D. Altamirano +2
We discovered kHz QPOs in 80 archived RXTE observations from the peculiar low-mass X-ray binary (LMXB) Circinus X-1. In 11 cases these appear in pairs in the frequency range of ~23…
