X-ray and Optical Variations in the Classical Be Star gamma Cas

Kavli Affiliate: Richard D. Robinson | First 5 Authors: Richard D. Robinson, Myron A. Smith, Gregory W. Henry, , | Summary: gamma Cas (B0.5e) is known to be a unique X-ray source because ot its moderate L_x, hard X-ray spectrum, and light curve punctuated by ubiquitous flares and slow undulations. Its X-ray peculiarities have led […]

Weakly non-linear analysis of wind-driven gravity waves

Kavli Affiliate: Robert Rosner | First 5 Authors: Alexandros Alexakis, Yuan-Nan Young, Robert Rosner, , | Summary: We study the weakly non-linear development of shear-driven gravity waves, and investigate the mixing properties of the finite amplitude solutions. Calculations to date have been restricted to the linear theory, which predicts that gravity waves are amplified by […]

Particle Astrophysics and Cosmology: Cosmic Laboratories for New Physics (Summary of the Snowmass 2001 P4 Working Group)

Kavli Affiliate: Daniel S. Akerib | First 5 Authors: Daniel S. Akerib, Sean M. Carroll, Marc Kamionkowski, Steven Ritz, | Summary: The past few years have seen dramatic breakthroughs and spectacular and puzzling discoveries in astrophysics and cosmology. In many cases, the new observations can only be explained with the introduction of new fundamental physics. […]

Special McKay correspondence

Kavli Affiliate: Yukari Ito | First 5 Authors: Yukari Ito, , , , | Summary: There are many generalizations of the McKay correspondence for higher dimensional Gorenstein quotient singularities and there are some applications to compute the topological invariants today. But some of the invariants are completely different from the classical invariants, in particular for […]

X-ray Spectra and Light Curves of AR Lac: Temperature Structure, Abundances, and Variability

Kavli Affiliate: Claude Canizares | First 5 Authors: David Huenemoerder, Claude Canizares, Kevin Tibbetts, , | Summary: We observed AR Lac, an eclipsing RS CVn binary star, with the Chandra High Energy Grating Spectrometer for a total of 100 ks divided into six intervals covering both quadratures and eclipses. We repeated observations at each phase. […]

Observations of Gamma-ray Bursts with the Rossi X-ray Timing Explorer

Kavli Affiliate: Edmund Bertschinger | First 5 Authors: Hale Bradt, Alan M. Levine, Francis E. Marshall, Ronald A. Remillard, Donald A. Smith | Summary: The role of the Rossi X-ray Timing Explorer (RXTE) in the study of Gamma-ray Bursts (GRBs) is reviewed. Through April 2001, the All-Sky Monitor (ASM) and the Proportional Counter Array (PCA) […]

String Theory on AdS Orbifolds

Kavli Affiliate: Emil Martinec | First 5 Authors: Emil Martinec, Will McElgin, , , | Summary: We consider worldsheet string theory on $Z_N$ orbifolds of $AdS_3$ associated with conical singularities. If the orbifold action includes a similar twist of $S^3$, supersymmetry is preserved, and there is a moduli space of vacua arising from blowup modes […]

A Useful Approximation to the Cooling Coefficient of Trace Elements

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Robert A. Benjamin, Bradford A. Benson, Donald P. Cox, , | Summary: Radiative cooling is an important ingredient in hydrodynamical models involving evolution of high temperature plasmas. Unfortunately, calculating an accurate cooling coefficient generally requires the solution of over a hundred differential equations to follow the […]
