Coronal mass ejection: key issues
Coronal Mass Ejections (CMEs) have been addressed by a particularly active research community in recent years. With the advent of the International Heliophysical Year and the new STEREO and Hinode missions, in addition to the on-going SOHO mission, CME research has taken centre stage in a renewed international effort. This review aims to touch on some key observational areas, and their interpre...
متن کاملRadiation-Pressure Ejection of Planetary Nebulae in Asymptotic-Giant-Branch Stars
We have investigated the possibility that radiation pressure might trigger planetary nebula (PN) ejection during helium-shell flashes in asymptotic-giant-branch (AGB) stars. We find that the outward flux at the base of the hydrogen envelope during a flash will reach the Eddington limit when the envelope mass Menv falls below a critical value that depends on the core mass MH and composition. The...
متن کاملMagnetic field and dynamic pressure ULF fluctuations in coronal-mass-ejection-driven sheath regions
Compressed sheath regions form ahead of interplanetary coronal mass ejections (ICMEs) that are sufficiently faster than the preceding solar wind. The turbulent sheath regions are important drivers of magnetospheric activity, but due to their complex internal structure, relatively little is known on the distribution of the magnetic field and plasma variations in them. In this paper we investigat...
متن کاملContinuous variable entanglement by radiation pressure
We show that the radiation pressure of an intense optical field impinging on a perfectly reflecting vibrating mirror is able to entangle in a robust way the first two optical sideband modes. Under appropriate conditions, the generated entangled state is of EPR type [A. Einstein, et al., Phys. Rev. 47, 777 (1935)]. PACS numbers: 42.50.Vk, 03.65.Ud, 03.67.-a
متن کاملUltrasound power measurement by pulsed radiation pressure
In a specially designed radiation force balance (RFB), low-frequency pulse modulation of the incident ultrasound allows high-accuracy measurement of time-averaged spatially-integrated ultrasound power radiated into a reflectionless water load. Errors characteristic of force sensors are precluded by operating the RFB as a force comparator, without directly measuring force. Equipped with purpose-...
