The CHARA Array Interferometric Program on the Multiplicity of Classical Be Stars: New Detections and Orbits of Stripped Subdwarf Companions

The Astrophysical Journal
Rapid rotation and nonradial pulsations enable Be stars to build decretion disks, where the characteristic line emission forms. A major but unconstrained fraction of Be stars owe their rapid rotation to mass and angular momentum transfer in a binary. The

Advancing from MOFs and COFs to Functional Macroscopic Porous Constructs

Advanced Materials, EarlyView.
This review study investigates the recent progress and methodologies for manufacturing metal–organic framework (MOF) or covalent–organic framework (COF)‐based 3D structured macroscopic porous constructs with high structural integrity, providing the possibility to control their porosity across dimensions.

The Puzzling Superorbital Period Variation of the Low-mass X-Ray Binary 4U 1820–30

The Astrophysical Journal
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.

Physical Environment of Accreting Neutron Stars

Advances in Astronomy, 2016
Neutron stars (NSs) powered by accretion, which are known as accretion-powered NSs, always are located in binary systems and manifest themselves as X-ray sources. Physical processes taking place during the accretion of material from their companions form

High-energy Jet Emission from GRS 1758–258 and 1E 1740.7–2942 with INTEGRAL?

The Astrophysical Journal
GRS 1758–258 and 1E 1740.7–2942 are two long-known persistent black hole binaries in the Galactic center region. Using the International Gamma-Ray Astrophysics Laboratory (INTEGRAL)'s extensive monitoring of the Galactic center and bulge, we studied ...
