Discovery of a Second Transient Low-Mass X-ray Binary in the Globular Cluster NGC 6440
C. O. Heinke, D. Altamirano, H. N. Cohn +11
We have identified a new transient luminous low-mass X-ray binary, NGC 6440 X-2, with Chandra/ACIS, RXTE/PCA, and Swift/XRT observations of the globular cluster NGC 6440. The disco…
Discovery of a 205.89 Hz accreting-millisecond X-ray pulsar in the globular cluster NGC 6440
D. Altamirano, A. Patruno, C. Heinke +6
We report the discovery of the second accreting millisecond X-ray pulsar (AMXP) in the globular cluster NGC 6440. Pulsations with a frequency of 205.89 Hz were detected with the Ro…
What ignites on the neutron star of 4U 0614+091?
E. Kuulkers, J. J. M. in 't Zand, J. -L. Atteia +10
[abridged] The LMXB 4U 0614+091 is a source of sporadic thermonuclear (type I) X-ray bursts. We find bursts with a wide variety of characteristics in serendipitous wide-field X-ray…
Type I X-ray bursts, burst oscillations and kHz quasi-periodic oscillations in the neutron star system IGR J17191-2821
D. Altamirano, M. Linares, A. Patruno +6
We present a detailed study of the X-ray energy and power spectral properties of the neutron star transient IGR J17191-2821. We discovered four instances of pairs of simultaneous k…
The disc-jet coupling in the neutron star X-ray binary Aquila X-1
V. Tudose, R. P. Fender, M. Linares +2
We study the accretion/ejection processes (i.e. disc/jet coupling) in the neutron star X-ray binary Aquila X-1 via a multi-wavelength approach. We use in the radio band the publicl…
Discovery of burst oscillations in the intermittent accretion-powered millisecond pulsar HETE J1900.1-2455
Anna L. Watts, Diego Altamirano, Manuel Linares +8
We report the discovery of burst oscillations from the intermittent accretion-powered millisecond pulsar (AMP) HETE J1900.1-2455, with a frequency approximately 1 Hz below the know…
