TL;DR: In this article, the authors derived a pulse phase model that connects two outbursts, providing a long baseline for spin frequency measurement, and suggested a modification in which the outburst is shut off by the onset of a propeller effect before the disk is depleted, which can explain the short quiescence and unusually slow rise of the light curve of the second 2008 outburst.

TL;DR: In this article, the authors presented an analysis of Chandra/LETGS observations of the ultracompact X-ray binary (UCXB) 4U 1626$-$67, continuing their project to analyze the existing Chandra gratings data of this interesting source.

TL;DR: The High-Energy X-ray Probe (HEX-P) is a probe-class mission concept that will extend the reach of broadband (2-200 keV) Xray observations, with 40 times the sensitivity of any previous mission in the 10-80 keV band and 10,000 times higher sensitivity in the 80-200 kV band as discussed by the authors.
