HI 2334+26: An Extended HI Cloud near Abell 2634

Riccardo Giovanelli, Marco Scodeggio, Jose` M. Solanes +3

We report the serendipitous discovery of a large HI cloud with an associated HI mass of M and a heliocentric velocity 8800 \kms, located near…

Spin-Up/Spin-Down of Magnetized Stars with Accretion Disks and Outflows

R. V. E. Lovelace, M. M. Romanova, G. S. Bisnovatyi-Kogan

An investigation is made of disk accretion of matter onto a rotating star with an aligned dipole magnetic field. A new aspect of this work is that when the angular velocity of the…

Images of HCO+ (1-0) Emission in a Molecular Cloud near 1E1740.7-2942

J. A. Phillips, T. Joseph W. Lazio

We have observed the hard X-ray source 1E1740.7-2942 in the HCO+ (1-0) line using the Owens Valley millimeter interferometer. Previous single dish observations have found HCO+ emis…

Hydrodynamic Evolution of Coalescing Compact Binaries

F. A. Rasio, S. L. Shapiro

In addition to their possible relevance to gamma-ray bursts, coalescing binary neutron stars have long been recognized as important sources of gravitational radiation that should b…

Hydrodynamics of Binary Coalescence. II. Polytropes with Gamma=5/3

F. A. Rasio, S. L. Shapiro

We present a new numerical study of the equilibrium and stability properties of close binary systems using the smoothed-particle hydrodynamics (SPH) technique. We adopt a simple po…

Deviations from Hierarchical Clustering in Real and Redshift Space

S. Ghigna, S. A. Bonometto, L. Guzzo +4

We discuss the effects of redshift--space distortions on the estimate of high order galaxy correlation functions. We use both the Perseus--Pisces redshift survey and the results of…

Resonant Oscillations and Tidal Heating in Coalescing Binary Neutron Stars

Dong Lai

Tidal interaction in a coalescing neutron star binary can resonantly excite the g-mode oscillations of the neutron star when the frequency of the tidal driving force equals the int…

Hydrodynamics of Rotating Stars and Close Binary Interactions: Compressible Ellipsoid Models

Dong Lai, Frederic A. Rasio, Stuart L. Shapiro

We develop a new formalism to study the dynamics of fluid polytropes in three dimensions. The stars are modeled as compressible ellipsoids and the hydrodynamic equations are reduce…

Hydrodynamics of Binary Coalescence.I. Polytropes with Stiff Equations of State

F. A. Rasio, S. L. Shapiro

We have performed a series of three-dimensional hydrodynamic calculations of binary coalescence using the smoothed particle hydrodynamics (SPH) method. The initial conditions are e…
