A possible solution of the puzzling variation of the orbital period of MXB 1659–298 [PDF]
, 2017 MXB 1659-298 is a transient neutron star Low-Mass X-ray binary system that shows eclipses with a periodicity of 7.1 hr. The source went to outburst in August 2015 after 14 years of quiescence.

The Orbital Period of V368 Aquilae (Nova Aquilae 1936 No. 2)
, 2009 We report observations of the eclipsing classical nova V368 Aql (Nova Aql 1936 No. 2). These data reveal that the orbital period previously published by Diaz & Bruch is an alias of the true orbital period.

Examination of Orbital Period of ZZ Cancri [PDF]
Journal of Astronomy and Space Sciences, 1989 A total of 266 photoeletric observation(91 in V, 93 in B, and 82 in U) for an eclipsing binary, ZZ Cnc, has been secured by using the 61-cm reflector and an uncooled 1P21 photomultiplier phototube of Yonsei University Observatory during 4 years from ...

X-Ray Eclipse Timing in the LMXB EXO0748-676
, 2004 Orbital period changes are an important diagnostic for understanding low mass X-ray binary (LMXB) accretion-induced angular momentum exchange and overall system evolution. We present our most recent results for the eclipse timing of the LMXB EXO0748-676.

The Planetary Mass–Radius Relation and Its Dependence on Orbital Period as Measured by Transit Timing Variations and Radial Velocities [PDF]
, 2017 The two most common techniques for measuring planetary masses—the radial velocity (RV) and the transit timing variation (TTV) techniques—have been observed to yield systematically different masses for planets of similar radii.

Quiescent photometric modulations of two low-inclination cataclysmic variables KZGem and TWVir
, 2017 The quiescent periodic photometric modulations of two low-inclination cataclysmic variables observed in Kepler K2 Campaigns 0 and 1, KZ Gem and TW Vir, are investigated. A phase-correcting method was successfully used to detect the orbital modulations of

Discovery of a 26.2 day period in the long-term X-ray light curve of SXP 1323: a very short orbital period for a long spin period pulsar [PDF]
, 2017 Context. About 120 Be/X-ray binaries (BeXBs) are known in the Small Magellanic Cloud (SMC); about half of them are pulsating with periods from a few to hundreds of seconds. SXP 1323 is one of the longest-period pulsars known in this galaxy. Aims.
