The Accretion-Ejection Instability: Observational Tests
QPOs are commonly considered to originate in the disks of X-ray binaries. One thus expects, and most often observes, that the QPO frequency decreases as the disk inner radius increases. However Sobczak et al. (19...

Phase Transitions In Sr 2 Co 2 O 5: a Neutron Diffraction Study
Sr2Co2O5, when quenched to room temperature from 910°C, adopts a metastable brownmillerite structure (B). This structure as a result of vacancy ordering in the parent perovskite SrCoO 3 ...
