Spectroscopy of Infrared Flares from the Microquasar GRS 1915+105
Stephen S. Eikenberry, Keith Matthews, Thomas W. Murphy +4
We present near-infrared medium-resolution () spectra of the microquasar GRS 1915+105 on 1997 August 13-15 UTC from the Hale 200-inch telescope. The spectra showed broa…
Resonant Thickening of Disks by Small Satellite Galaxies
J. A. Sellwood, Robert W. Nelson, Scott Tremaine
We study the vertical heating and thickening of galaxy disks due to accretion of small satellites. Our simulations are restricted to axial symmetry, which largely eliminates numeri…
Evidence for a Disk-Jet Interaction in the Microquasar GRS 1915+105
S. S. Eikenberry, K. Matthews, E. H. Morgan +2
We report simultaneous X-ray and infrared (IR) observations of the Galactic microquasar GRS1915+105 using XTE and the Palomar 200-inch telescope on August 13-15, 1997 UTC. During t…
Linear Response, Dynamical Friction and the Fluctuation-Dissipation Theorem in Stellar Dynamics
Robert W. Nelson, Scott Tremaine
We apply linear response theory to a general, inhomogeneous, stationary stellar system, with particular emphasis on dissipative processes analogous to Landau damping. Assuming only…
On the Correlation of Torque and Luminosity in GX 1+4
Deepto Chakrabarty, Lars Bildsten, Mark H. Finger +6
Over five years of daily hard X-ray (>20 keV) monitoring of the 2-min accretion-powered pulsar GX 1+4 with the Compton Gamma Ray Observatory/BATSE large-area detectors has found ne…
The Dynamics of Galactic Warps
Robert W. Nelson, Scott Tremaine
Large-scale warps in the outer parts of spiral galaxy discs have been observed for almost forty years, but their origin remains obscure. We review the dynamics of warped galaxy dis…
A Potential Cyclotron Line Signature in Low Luminosity X-Ray Sources
Robert W. Nelson, John C. L. Wang, E. E. Salpeter +1
Estimates indicate there may be $\simgreat 10^3$ low luminosity X-ray pulsars ($L \simless 10^{34} \rom{erg\;s^{-1}}$) in the Galaxy undergoing ``low-state'' wind accretion in Be/X…
The Damping and Excitation of Galactic Warps by Dynamical Friction
Robert W. Nelson, Scott Tremaine
We investigate the dynamical interaction of galactic warps with the surrounding dark matter halo, using analytic perturbation theory. A precessing warp induces a density wake in th…
