The global kinematics of the Dumbbell planetary nebula (NGC 6853, M27, PN G060.8-03.6)
J. Meaburn, P. Boumis, P. E. Christopoulou +3
Spatially resolved profiles of the HeII 6560 A, Halpha and [N II] 6548 & 6584 A nebular emission lines have been obtained in two orthogonal long cuts over the Dumbbell planetary ne…
The Galactic Formation Rate of Eccentric Neutron Star-White Dwarf Binaries
Vassiliki Kalogera, Chunglee Kim, Duncan R. Lorimer +2
In this paper we consider the population of eccentric binaries with a neutron star and a white dwarf that has been revealed in our galaxy in recent years through binary pulsar obse…
The Galactic Double-Neutron-Star Merger Rate: Most Current Estimates
Chunglee Kim, Vassiliki Kalogera, Duncan R. Lorimer +2
We summarize our results on the Galactic merger rate of double neutron stars (DNS) in view of the recent discovery of PSR J0737-3039. We also present previously unpublished results…
New Planetary Nebulae in the Northern Galactic Plane
Panayotis Boumis, Myfanwy Bryce
We present deep Halpha+[N II] CCD images of selected new Planetary Nebulae (PNe) discovered through an [O III] 5007 A emission line survey in the Galactic Bulge region with l > 0 d…
Giant pulses in Millisecond Pulsars
B. C. Joshi, M. Kramer, A. G. Lyne +2
Giant pulses (GPs), occasional individual pulses with an intensity 100 times the average intensity, have been detected in four pulsars todate. Their origin is not well understood,…
Threshold amplitudes for transition to turbulence in a pipe
Lloyd N. Trefethen, S. J. Chapman, Dan S. Henningson +3
Although flow in a circular pipe is stable to infinitesimal perturbations, it can be excited to turbulence by finite perturbations whose minimal amplitude shrinks as R goes to infi…
