Candidate mHz QPOs detected in GX 3+1 at 7-15 mHz with 0.51-1.41% rms, one surviving global significance, occurring at higher luminosities than in other NS LMXBs.
A new relativistic model for accretion-powered X-ray pulsars enables simultaneous computation of phase-averaged spectra and pulse profiles, applied to NuSTAR data for Her X-1 to extract physical parameters and beaming patterns.
New observations of 4U 1323-62 detect 12 bursts, confirm 2.94-hour dips, a 0.9 Hz QPO, and suggest a ~10-year cyclic variation in burst rate.
Marginal X-ray polarization detection in atoll source 4U 1735-44 is consistent with a low disk inclination of about 40 degrees inferred from relativistic reflection modeling.
Simultaneous X-ray and optical observation of a type I burst in EXO 0748-676 shows a 4.46 s optical lag after 16 years of quiescence.
Observations show a long thermonuclear burst in MAXI J0911--655 followed by a flare interpreted as burst-driven thermal-viscous disk instability enhancing accretion.
Observational analysis of type-II bursts in MXB 1730-335 confirms mode-dependent power-law relations between burst fluence and recurrence time plus a critical fluence threshold for peak-flux correlation.
XSPECT observations of two soft X-ray transients during outburst decay reveal superburst evolution with cooling blackbody emission and a flux-dependent hardening of Comptonized spectra.
Significant X-ray flux blocking in 4U 1746-37 allows the neutron star to have canonical mass and radius values of 1.59 solar masses and 13 km or 2.12 solar masses and 9.8 km.
NuSTAR and NICER data on SAX J1808.4-3658 show the accretion disk truncating to ~23 R_g in 2025 with magnetospheric radius exceeding co-rotation radius, indicating a possible transition to the propeller regime while accretion continues as evidenced by a Type-I burst.
Discovery of an eclipsing neutron star LMXB with clocked bursts, orbital period 6.483 hr, companion mass 0.6-0.8 Msun, and helium burst indications from energy ratio 120-130.
