Burning in the tail: implications for a burst oscillation model
Frank R. N. Chambers, Anna L. Watts, L. Keek +2
Accreting neutron stars (NS) can exhibit high-frequency modulations, known as burst oscillations, in their lightcurves during thermonuclear X-ray bursts. Their frequencies can be o…
NICER Detection of Strong Photospheric Expansion during a Thermonuclear X-Ray Burst from 4U 1820-30
L. Keek, Z. Arzoumanian, D. Chakrabarty +13
The Neutron Star Interior Composition Explorer (NICER) on the International Space Station (ISS) observed strong photospheric expansion of the neutron star in 4U 1820-30 during a Ty…
NICER Observes the Effects of an X-Ray Burst on the Accretion Environment in Aql X-1
L. Keek, Z. Arzoumanian, P. Bult +18
Accretion disks around neutron stars regularly undergo sudden strong irradiation by Type I X-ray bursts powered by unstable thermonuclear burning on the stellar surface. We investi…
NICER Discovers the Ultracompact Orbit of the Accreting Millisecond Pulsar IGR J17062-6143
Tod E. Strohmayer, Zaven Arzoumanian, Slavko Bogdanov +17
We present results of recent Neutron Star Interior Composition Explorer observations of the accreting millisecond X-ray pulsar IGR J17062-6143 that show that it resides in a circul…
NICER Discovers mHz Oscillations in the "Clocked" Burster GS 1826-238
Tod E. Strohmayer, Keith C. Gendreau, Diego Altamirano +12
We report the discovery with the Neutron Star Interior Composition Explorer (NICER) of mHz X-ray brightness oscillations from the "clocked burster." NICER observed the source in th…
Nuclear Physics of the Outer Layers of Accreting Neutron Stars
Zach Meisel, Alex Deibel, Laurens Keek +2
Now 50 years since the existence of the neutron star crust was proposed, we review the current understanding of the nuclear physics of the outer layers of accreting neutron stars.…
