Haro 5-2: A New Pre-Main Sequence Quadruple Stellar System
Bo Reipurth, C. Briceno, T. R. Geballe +9
We have discovered that the Halpha emission line star Haro 5-2, located in the 3-6 Myr old Ori OB1b association, is a young quadruple system. The system has a 2+2 configuration wit…
The effect of the Solar motion on the flux of long-period comets
E. Gardner, P. Nurmi, C. Flynn +1
The long-term dynamics of Oort cloud comets are studied under the influence of both the radial and the vertical components of the Galactic tidal field. Sporadic dynamical perturbat…
Measuring Black Hole Spin in OJ287
M. Valtonen, S. Mikkola, H. J. Lehto +8
We model the binary black hole system OJ287 as a spinning primary and a non-spinning secondary. It is assumed that the primary has an accretion disk which is impacted by the second…
Measuring the spin of the primary black hole in OJ287
M. J. Valtonen, S. Mikkola, D. Merritt +7
The compact binary system in OJ287 is modelled to contain a spinning primary black hole with an accretion disk and a non-spinning secondary black hole. Using Post Newtonian (PN) ac…
A Hybrid N-Body Code Incorporating Algorithmic Regularization and Post-Newtonian Forces
S. Harfst, A. Gualandris, D. Merritt +1
We describe a novel N-body code designed for simulations of the central regions of galaxies containing massive black holes. The code incorporates Mikkola's 'algorithmic' chain regu…
