We report on millisecond variability from the X-ray transient XTE J1739-285. We detected six X-ray type I bursts and found evidence for oscillations at 1122 ± 0.3 Hz in the brightest X-ray burst. Taking into consideration the power in the oscillations and the number of trials in the search, the detection is significant at the 99.96% confidence level. If the oscillations are confirmed, the oscillation frequency would suggest that XTE J1739-285 contains the fastest rotating neutron star yet found… 
The X-Ray Bursts of XTE J1739–285: A NICER Sample
In this work, we report on observations with the Neutron Star Interior Composition Explorer of the known neutron star X-ray transient XTE J1739–285. We observed the source in 2020 February and March,
A Uniform Search for Thermonuclear Burst Oscillations in the RXTE Legacy Data Set
We describe a blind uniform search for thermonuclear burst oscillations (TBOs) in the majority of Type I bursts observed by the Rossi X-ray Timing Explorer (RXTE) (2118 bursts from 57 neutron stars).
Generation of Type I X-Ray Burst Oscillations by Unstable Surface Modes
The Rossi X-ray Timing Explorer has detected nearly coherent oscillations in the tails of type I X-ray bursts from 17 low-mass X-ray binaries. The oscillations are thought to be generated by
X-RAY OUTBURSTS OF LOW-MASS X-RAY BINARY TRANSIENTS OBSERVED IN THE RXTE ERA

Thermonuclear (Type I) X-Ray Bursts Observed by the Rossi X-Ray Timing Explorer
We have assembled a sample of 1187 thermonuclear (type I) X-ray bursts from observations of 48 accreting neutron stars by the Rossi X-ray Timing Explorer, spanning more than 10 years. The sample
A Deep Pulse Search in 11 Low Mass X-Ray Binaries
We present a systematic coherent X-ray pulsation search in 11 low mass X-ray binaries (LMXBs). We select a relatively broad variety of LMXBs, including persistent and transient sources, spanning
Accreting Neutron Stars in Low-Mass X-Ray Binary Systems
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-frequency X-ray
Recent study about the correlations between the spin frequencies and kHz QPOs of Neutron Stars in LMXBs
Aims. We studied the correlations between spin frequencies and kilohertz quasi-periodic oscillations ( kHz QPOs) in neutron star low-mass X-ray binaries. Methods. The updated data on kHz QPOs and
Thermonuclear Burst Oscillations
Burst oscillations, a phenomenon observed in a significant fraction of Type I (thermonuclear) X-ray bursts, involve the development of highly asymmetric brightness patches in the burning surface
Does Submillisecond Pulsar XTE J1739-285 Contain a Weak Magnetic Neutron Star or Quark Star?
The possible detection of the fastest spinning nuclear‐powered pulsar XTE J1739−285, of frequency 1122 Hz (0.8913 ms), arouses us to constrain the mass and radius of its central compact object and to

A Radio Pulsar Spinning at 716 Hz
TLDR
A 716-hertz eclipsing binary radio pulsar in the globular cluster Terzan 5 using the Green Bank Telescope is discovered, it is the fastest spinning neutron star found to date, and constrains models that suggest that gravitational radiation, through an r-mode (Rossby wave) instability, limits the maximum spin frequency of neutron stars.
