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…
A Young White Dwarf Companion to Pulsar 1620-26: Evidence for Early Planet Formation
Steinn Sigurdsson, Harvey B. Richer, Brad M. Hansen +2
The pulsar B1620-26 has two companions, one of stellar mass and one of planetary mass. We detected the stellar companion using Hubble Space Telescope observations. The color and ma…
Survival of Terrestrial Planets in the Presence of Giant Planet Migration
Avi M. Mandell, Steinn Sigurdsson
The presence of ``Hot Jupiters'', Jovian mass planets with very short orbital periods orbiting nearby main sequence stars, has been proposed to be primarily due to the orbital migr…
Loss cone: past, present and future
Steinn Sigurdsson
The capture and subsequent in--spiral of compact stellar remnants by central massive black holes, is one of the more interesting likely sources of gravitational radiation detectabl…
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…
