Stellar Collisions and Blue Straggler Formation

open access: yes, 2001
We review recent 3D hydrodynamic calculations of stellar collisions using the Smoothed Particle Hydrodynamics (SPH) method, and we discuss the implications of the results for the formation and evolution of blue stragglers in globular clusters. We also discuss the construction of simple analytic models for merger remnants, approximating the mass loss ...

Observation of Topological Spin Textures in Ferrimagnetic Mn2 − xZnxSb

open access: yesSmall, EarlyView.
Mn2 − xZnxSb crystal has ferrimagnetic order due to the anti‐aligned spins at two inequivalent Mn sites. Magnetic property of the ferrimagnet can be tuned by external stimuli (such as the temperature and the magnetic field), resulting in a variety of spin textures.

Imaging of Recombination Rates and Lifetime in Perovskite Thin Film Processing

open access: yesSmall Methods, EarlyView.
Achieving consistent, homogeneous layer quality in perovskite thin films is a critical challenge for large‐scale processing. This study introduces relative photoluminescence quantum yield (rPLQY)‐imaging, a novel, non‐invasive imaging technique that enables spatially resolved characterization of fundamental optoelectronic characteristics.
