Observational Signature of Tidal Disruption of a Star by a Massive Black Hole
Tamara Bogdanovic, Michael Eracleous, Suvrath Mahadevan +2
We have modeled the time-variable profiles of the Balmer alpha emission from the nonaxisymmetric disk and debris tail created in the tidal disruption of a solar-type star by a mill…
Finding Extrasolar Planets in the Stellar Graveyard with the Hubble Space Telescope
John H. Debes, Steinn Sigurdsson, Bruce E. Woodgate
In order to directly image an extrasolar planet, the large contrast between a star and a companion planet must be overcome. White Dwarfs (WDs) are the remnants of stars > 1 M_sun a…
Update on Pulsar B162026 in M4: Observations, Models, and Implications
Steinn Sigurdsson, Stephen E. Thorsett
The combination of ever more precise radio timing data and serendipitous {\it HST} data has confirmed that the outer companion to PSR B162026 is a planet. Here we summarize the…
Simulating the Early Evolution of the Hard X-Ray Properties of a Young Stellar Population
M. S. Sipior, M. Eracleous, S. Sigurdsson
We present an X-ray binary population synthesis model, and use it to simulate the evolution of X-ray binaries formed in a burst of star formation of duration 20 Myr and star-format…
Adiabatic Growth of Massive Black Holes
Steinn Sigurdsson
We discuss the process of adiabatic growth of central black holes in the presence of a stationary, pre-existing distribution of collisionless stars. Within the limitations of the a…
A Lack of Planets in 47 Tucanae from an HST Search
Ronald L. Gilliland, T. M. Brown, P. Guhathakurta +21
We report results from a large Hubble Space Telescope project to observe a significant (~34,000) ensemble of main sequence stars in the globular cluster 47 Tucanae with a goal of d…
