I will show that binary eccentricities evolve towards steady state values that increase with mass ratio, and saturate at an equilibrium eccentricity e_{b,eq} ~ 0.5 in the large mass ratio regime. This result is in line with resonant theory. For binaries accreting at their combined Eddington limit, a steady state eccentricity can be achieved within a few Megayears. Once at their steady state eccentricities, binaries with mass ratios greater than q_b > 0.3 evolve towards coalescence, while lower mass ratio systems expand due to CBD torques. I will discuss implications for population studies of massive black hole binaries, protostars in binary systems, and post-common envelope binaries observed by ground-based gravitational wave detectors. | 19 Panagiotis Charalambous, Magic Zeroes in the Black Hole Response Problem and a Love Symmetry Resolution (10:00 AM) , HEP Journal Club (12:30 PM - 1:30 PM) David B Kaplan, Topological materials and relativistic fermions (2:00 PM - 3:15 PM) + Abstract: | 20 , Equity & Inclusion Committee (12:30 PM - 2:00 PM) Satya Gontcho A Gontcho, Dark Energy Spectroscopic Instrument: overview and early results (12:30 PM - 1:15 PM) Kathryn Moler, Unquantized Vortices in Superconductors (4:00 PM - 5:15 PM) | 21 , Research Fair (2:00 PM - 5:00 PM) Zare (3:30 PM - 5:30 PM) |
