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.

Constraining the period of the ringed secondary companion to the young star J1407 with photographic plates [PDF]
, 2018 Context. The 16 Myr old star 1SWASP J140747.93-394542.6 (V1400 Cen) underwent a series of complex eclipses in May 2007, interpreted as the transit of a giant Hill sphere filling debris ring system around a secondary companion, J1407b.

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

A short-period censor of sub-Jupiter mass exoplanets with low density [PDF]
, 2010 Despite the existence of many short-period hot Jupiters, there is not one hot Neptune with an orbital period less than 2.5 days. Here we discuss a cluster analysis of the currently known 106 transiting exoplanets to investigate a possible explanation for

Light curve solutions and out-of-eclipse variability of KIC 10031409, KIC 11228612, KIC 11403216 and KIC 11913071 [PDF]
Serbian Astronomical Journal, 2017 We carried out light curve solutions of four detached binaries observed by Kepler. As a result, their orbital inclinations, temperatures and relative stellar radii were determined.

ON THE ORIGIN OF THE SUB-JOVIAN DESERT IN THE ORBITAL-PERIOD–PLANETARY-MASS PLANE [PDF]
, 2016 Transit and radial velocity observations indicate a dearth of sub-Jupiter-mass planets on short-period orbits, outlined roughly by two oppositely sloped lines in the period–mass plane.

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.

A reduced orbital period for the supermassive black hole binary candidate in the quasar PG 1302-102? [PDF]
, 2015 Graham et al. (2015) have detected a 5.2 year periodic optical variability of the quasar PG 1302-102 at redshift $z=0.3$, which they interpret as the redshifted orbital period $(1+z)t_{\rm bin}$ of a putative supermassive black hole binary (SMBHB).

Eclipse Timings of the LMXB XTE J1710-281: Orbital Period Glitches
, 2010 We present an X-ray eclipse timing analysis of the transient low mass X-ray binary XTE J1710-281. We report observations of 57 complete X-ray eclipses, made with the proportional counter array detectors aboard the RXTE satellite. Using the eclipse timing

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective The optimal treatment for neurosarcoidosis myelitis is uncertain. We characterize incident neurosarcoidosis myelitis and assess treatment response by MRI and clinical scales. Methods Incident probable or definite neurosarcoidosis myelitis in adults was retrospectively identified from 13 academic medical centers.
