Structure and dynamics of candidate O star bubbles in N44 [PDF]

open access: yes, 2002
peer reviewedDynamical studies of superbubbles and Wolf-Rayet ring nebulae show discrepancies from the standard adiabatic model for windblown bubbles. We therefore study the physical properties and kinematics of three candidate bubbles blown by single O ...

Strongly base-paracompact spaces [PDF]

open access: yes, 2003
summary:A space $X$ is said to be {\it strongly base-paracompact\/} if there is a basis $\Cal B$ for $X$ with $|\Cal B|=w(X)$ such that every open cover of $X$ has a star-finite open refinement by members of $\Cal B$.

Properties of strongly star shaped cones

open access: yes, 2007
In problems of vector optimization, with preferences that are not necessarily a pre-order relation, the strongly star shaped cones are very important in order to get a scalarization of these problems.

Interfaces in Numerical Relativistic hydrodynamics

open access: yes, 2010
This thesis investigates numerical techniques for modelling sharp interfacesbetween relativistic fluids. The motivation for this work lies in obtaining accuratemodels of neutron star interiors for use in multidimensional simulationsin general relativity.

AN EXAMPLE OF USING STAR COMPLEMENTS IN CLASSIFYING STRONGLY REGULAR GRAPHS ∗

open access: yes, 2014
In this paper we show how the star complement technique can be used to reprove the result of Wilbrink and Brouwer that the strongly regular graph with parameters (57, 14, 1, 4) does not exist.

Signals of the QCD Phase Transition in the Heavens

open access: yes, 2007
The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

Results from the STAR experiment

open access: yes, 2002
Collisions of heavy ions at RHIC are expected to exceed the energy densities required to achieve a phase transition to the quark gluon plasma (QGP) [1,2].

Induced star formation in interacting galaxies

open access: yes, 1987
Measurements of H alpha emission line fluxes and FIR fluxes in approx. 100 interacting spirals were used to investigate the effects of close tidal interactions on the disk and nuclear star formation rates in galaxies.

Bright transients from strongly-magnetized neutron star-black hole mergers [PDF]

open access: yes, 2016
Direct detection of black hole-neutron star pairs is anticipated with the advent of aLIGO. Electromagnetic counterparts may be crucial for a confident gravitational-wave detection as well as for extraction of astronomical information.
