Relations between Timing Features and Colors in the X-Ray Binary 4U 0614+09 [PDF]
, 2000 We study the correlations between timing and X-ray spectral properties in the low-mass X-ray binary 4U 0614+09 using a large (265 ks) data set obtained with the Rossi X-Ray Timing Explorer.

Disc–jet coupling in an atoll-type neutron star X-ray binary: 4U 1728–34 (GX 354–0) [PDF]
, 2003 We have analysed 12 simultaneous radio (Very Large Array) and X-ray (RXTE) observations of the atoll-type X-ray binary 4U 1728-34, performed in two blocks in 2000 and 2001.

Physical parameters of the high-mass X-ray binary 4U1700-37 [PDF]
, 2002 We present the results of a detailed non-LTE analysis of the ultraviolet and optical spectrum of the O6.5 Iaf + star HD 153919 - the mass donor in the high-mass X-ray binary 4U1700-37.

On X‐Ray Variability in Active Binary Stars
The Astrophysical Journal, 1999 We compare the count-rates of active binaries observed by Einstein and ROSAT. We find significant evidence for short-term variability (approx 0.32) and marginal evidence for a larger variability at longer timescales (approx 0.38). Modeling this excess as cyclic variability, we place an upper limit on the relative amplitude of the cyclic component ...

High-Mass X-Ray Binaries and OB Runaway Stars [PDF]
International Astronomical Union Colloquium, 2004 AbstractHigh-mass X-ray binaries (HMXBs) represent an important phase in the evolution of massive binary systems and provide fundamental information on the properties of the OB-star primaries and their compact secondaries (neutron star, black hole). Recent observations indicate that the neutron stars in some of these systems (Vela X-1, 4U 1700-37) are ...

Search for intermittent X-ray pulsations from neutron stars in low-mass X-ray binaries [PDF]
Publications of the Astronomical Society of Australia, 2021 AbstractWe present the results of our extensive binary orbital motion corrected pulsation search for 13 low-mass X-ray binaries. These selected sources exhibit burst oscillations in X-rays with frequencies ranging from 45 to 1 122 Hz and have a binary orbital period varying from 2.1 to 18.9 h.

SXP 1062, a young Be X-ray binary pulsar with long spin period - implications for the neutron star birth spin [PDF]
, 2011 Context. The Small Magellanic Cloud (SMC) is ideally suited to investigating the recent star formation history from X-ray source population studies. It harbours a large number of Be/X-ray binaries (Be stars with an accreting neutron star as companion ...

JET MODELS FOR NEUTRON STAR X-RAY BINARIES
International Journal of Modern Physics: Conference Series, 2012 A variety of different models for jet formation have been developed over the years (mainly) for black hole systems and young stellar objects. Conclusive observational constraints which would favor one particular mechanism are difficult to obtain.

EVIDENCE FOR A CONSTANT INITIAL MASS FUNCTION IN EARLY-TYPE GALAXIES BASED ON THEIR X-RAY BINARY POPULATIONS, [PDF]
, 2014 A number of recent studies have proposed that the stellar initial mass function (IMF) of early type galaxies varies systematically as a function of galaxy mass, with higher mass galaxies having bottom-heavy IMFs.

Donor Stars in Black Hole X‐Ray Binaries [PDF]
The Astrophysical Journal, 1999 We study theoretically the formation of black-hole (BH) X-ray binaries. Consistency of the models with the observed relative numbers of systems with low-mass (<2 M_sun) and intermediate-mass (~2 M_sun - M_{BH}) donors leads to severe constraints on the evolutionary parameters of the progenitors.
