Black Hole Mass Determinations From Orbit Superposition Models are Reliable
Douglas Richstone, Karl Gebhardt, Monique Aller +13
We show that orbit-superposition dynamical models (Schwarzschild's method) provide reliable estimates of nuclear black hole masses and errors when constructed from adequate orbit l…
The Dynamical Evolution of Dense Rotating Systems: Paper II. Mergers and Stellar Evolution
John S. Arabadjis, Douglas O. Richstone
We report the results of simulations of dense rotating stellar systems whose members suffer collisions and undergo stellar evolution processes. The initial configuration for each e…
The Dynamical Evolution of Dense Rotating Systems: Paper I. Two-Body Relaxation Effects
John S. Arabadjis, Douglas O. Richstone
This paper, and its companion, investigate the evolution of dense stellar systems due to the influence of two-body gravitational encounters, physical collisions and stellar evoluti…
The Quadruple Gravitational Lens PG1115+080: Time Delays and Models
P. L. Schechter, C. D. Bailyn, R. Barr +24
Optical photometry is presented for the quadruple gravitational lens PG1115+080. A preliminary reduction of data taken from November 1995 to June 1996 gives component ``C'' leading…
