The Puzzling Superorbital Period Variation of the Low-mass X-Ray Binary 4U 1820–30
Because of the previously observed stability of the 171 days period, the superorbital modulation of the low-mass X-ray binary 4U 1820–30 was considered a consequence of a third star orbiting around the binary.

Adsorption and Separation by Flexible MOFs
Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,

Silicon K-edge Dust Properties of Neutron Star Low-mass X-ray Binaries
AbstractThe dust properties of the line-of-sight materials in neutron star low-mass X-ray binaries (LMXBs) can be probed by X-ray observations and laboratory experiments. We use a Markov chain Monte Carlo (MCMC) method to conduct a spectral analysis of Chandra ACIS-S/HETG archival data of a sample of LMXBs, including GX 5-1 and GX 13+1.
