    Notes: [Auszug] To determine the mass it is necessary to observe the immediate shifts DW, DW and DW in the angular frequency (and its first two time derivatives) caused by the starquake. From these observations one can form the dimensionless parameter Q = (An)2/AQAii (1) In the two component model Q is given by ...

    Notes: This second of the annual Stockton Lectures starts by reflecting on the achievements of the founding fathers of the modern world economy in the immediate aftermath of World War II. Their legacy has been increasing interdependence and globalisation. Peter Sutherland argues that these have had a positive impact almost throughout the world and that these positive consequences of the market economy system do not necessarily have to be associated with increasing gaps between the rich and poor. He makes the case for multinationals to show commitment to what he calls “the common good” (as opposed only to shareholder returns). He examines the fundamental contradiction between free trade and national sovereignty and argues for more supranational (rather than just intergovernmental) decision-making and implementation. However, he also emphasises that some areas are not appropriate for integration or supranational action, most notably tax and workers’ rights. These should remain within the domain of national governments. He concludes by discussing threats to the world economy posed by the tension between the US and the EU on trade-related issues, and argues that inappropriate use of the WTO process threatens to destroy the whole system which has yielded so many economic benefits worldwide since 1945.

    Notes: Abstract In neutron star matter over the density range 4.3×1011〈-ϱ≤4×1014 g cm−3 there are both free neutrons and neutron-rich nuclei. If there is a weak neutral current interaction between neutrinos and neutrons, as suggested by recent experiments, then when neutrons scatter off nuclei they may emit $$v\bar v$$ pairs as bremsstrahlung radiation. We calculate the associated emissivity for degenerate (but not superfluid) neutrons and uncorrelated (not crystallized) nuclei. We find that, under these conditions. this emissivity can under some conditions compare with that calculated by Festa and Ruderman for $$v\bar v$$ bremsstrahlung in electron-nucleus collisions.

    Notes: Abstract Neutrinos couple through a weak neutral current to the density of matter, in particular to the neutron density. Density fluctuations, or phonons, in the neutron fluid may be emitted or absorbed by neutrinos passing through the matter. At high densities, temperatures and neutrino energies the neutrino mean free paths for phonon emission and absorption can be ≤106 cm. Significant changes in the neutrino momentum and energy accompany these processes. We present a model calculation for neutrino scattering by phonons, and representative numerical results for the neutrino mean free path and mean energy and momentum changes fork B T andE v both ranging from 1 to 27 MeV.

    Notes: Abstract In the presence of a strong magnetic field (such as those believed to be characteristic of neutron stars:B≳-1012 Gauss) positronium may annihilate through the emission of a single photon, the magnetic field providing the photon momentum. We report on calculations of the one-photon and two-photon annihilation rates for the ground state of positronium, for magnetic fields in the range (1–44)×1012 Gauss, and give, in the two-photon case, the minimum energy half-width of the emission line due to the momentum contributions from the magnetic field. We find that unless neutron stars have magnetic fields in excess of 1013 Gauss, it is unlikely that the one-photon process will be observable.

    Notes: Abstract Carbon-oxygen white dwarfs may be the progenitors of type-I supernovae. Spherically-symmetric models of such dwarfs have been evolved from an artificial core incineration. The convectively unstable incinerated region was allowed to grow at a velocity prescribed by the mixing-length theory of convection. The mixing length can be varied to give different cases. In all the cases considered the dwarfs exploded and were totally disrupted. The calculations were stopped after the dwarf matter had gone into homologous expansion. The model with the best estimated mixing length incinerated 0.8M ⊙. The energy released in burning this amount of carbon-oxygen to56Ni provides a disrupted dwarf with velocities suitable for type-I supernovae.

    Description: Sea ice in the Southern Ocean has expanded over most of the past 20 y, but the decline in sea ice since 2016 has taken experts by surprise. This recent evolution highlights the poor performance of numerical models for predicting extent and thickness, which is due to our poor understanding of ice dynamics. Ocean waves are known to play an important role in ice break-up and formation. In addition, as ocean waves decay, they cause a stress that pushes the ice in the direction of wave propagation. This wave stress could not previously be quantified due to insufficient observations at large scales. Sentinel-1 synthetic aperture radars (SARs) provide high-resolution imagery from which wave height is measured year round encompassing Antarctica since 2014. Our estimates give an average wave stress that is comparable to the average wind stress acting over 50 km of sea ice. We further reveal highly variable half-decay distances ranging from 400 m to 700 km, and wave stresses from 0.01 to 1 Pa. We expect that this variability is related to ice properties and possibly different floe sizes and ice thicknesses. A strong feedback of waves on sea ice, via break-up and rafting, may be the cause of highly variable sea-ice properties.
