... Further, in Chapter 6, we have seen that a magnetic field changing with time gives rise to an electric field. Is the converse also true? Does an electric field changing with time give rise to a magnetic field? James Clerk Maxwell (1831-1879), argued that this was indeed the case – not only an electr ...

Recent Measurements of Millisecond Pulsar Masses
... • Several neutron star masses have been measured precisely. Almost all of these are in DNS systems, like PSR B1913+16 or PSR J0737-3039. This happens because they have eccentric orbits, where more relativistic effects can be measured. Their masses range from 1.25 to 1.44 solar masses. • Because of p ...

A relativistic beam-plasma system with electromagnetic waves

The derivation proceeds from the relativistic action principle for particles coupled to Maxwell’s equations, and the reduction procedure developed results in model equations that inherit Lagrangian and Hamiltonian structure. Thus, the second purpose of this paper is to demonstrate how to systematica ...

The AD775 cosmic event revisited: the Sun is to blame
... AD775. Using a simple model, M12 claimed that the event was too strong to be caused by a solar flare within the standard theory. This implied a new paradigm of either an impossibly strong solar flare or a very strong cosmic ray event of unknown origin that occurred around AD775. However, as we show, ...

Mergers of massive main sequence binaries
... In the rapid phase of mass transfer, the initial phase of mass transfer in case A systems, mass is transferred from the more massive primary to the less massive secondary, which causes the orbit to shrink. The shrinking orbit implies a decrease of the Roche-lobe radius (Eq. 2), such that the equilib ...

Evolution of supermassive stars as a pathway to black hole formation

Since the thermonuclear timescale for a star burning hydrogen at the Eddington limit is ∼ 2 Myr, independent of mass, and will be less if on ...
