Scenarios for ultrafast gamma-ray variability in AGN [PDF]
, 2017 We analyze three scenarios to address the challenge of ultrafast gamma-ray variability reported from active galactic nuclei. We focus on the energy requirements imposed by these scenarios: (i) external cloud in the jet, (ii) relativistic blob propagating

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Solar Wind–Magnetosphere Coupling by the Kelvin–Helmholtz Instability at Mercury
The Astrophysical JournalThe Kelvin–Helmholtz instability (KHI) has been considered important in the energy transfer and momentum coupling between the solar wind and planetary magnetospheres.

On the self-consistent model of the axisymmetric radio pulsar magnetosphere
, 1998 We consider a model of axisymmetric neutron star magnetosphere. In our approach, the current density in the region of open field lines is constant and the returning current flows in a narrow layer along the separatrix.

MHD simulations of accretion onto a dipolar magnetosphere. II. Magnetospheric ejections and stellar spin-down [PDF]
, 2012 This paper examines the outflows associated with the interaction of a stellar magnetosphere with an accretion disk. In particular, we investigate the magnetospheric ejections (MEs) due to the expansion and reconnection of the field lines connecting the ...

Reverse convection potential saturation during northward IMF
Geophysical Research Letters, 2008 We report the results of an investigation of the reverse convection potentials in the day side high latitude ionosphere during periods of steady northward interplanetary magnetic field (IMF).

High latitude magnetospheric topology and magnetospheric substorm [PDF]
Annales Geophysicae, 2009 Abstract. This study is focused on the problem of the localization of substorm expansion onset. In this context, the high latitude topology of transverse magnetospheric currents has been analyzed. This study has included the radial distribution of plasma pressure near noon, obtained using the THEMIS-B satellite data, the daytime compression of magnetic

Orbital modulation of emission of the binary pulsar J0737-3039B
, 2005 In binary radio pulsar system J0737-3039, slow pulsar B shows orbital modulations of intensity, being especially bright at two short orbital phases. We propose that these modulations are due to distortion of pulsar B magnetosphere by pulsar A wind which ...

Transport of Mirror Mode Structures through Saturn’s Magnetopause Reconnection
The Astrophysical JournalMagnetopause reconnection plays a significant role in transferring plasma and energy from the solar wind to planetary magnetospheres. Using a Cassini measurement, we reported a magnetopause reconnection at Saturn, identified by the Hall magnetic field ...
