N-Body Simulations of Planetesimal Evolution:Effect of Varying Impactor Mass Ratio
planetesimals asteroids planetary formation collisional physics
2015/12/25
We present results from direct N-body simulations of collisions between gravitational aggregates of varying size as part of a study to parameterize planetesimal growth in the Solar System. We find tha...
Microinstabilities at perpendicular collisionless shocks: A comparison of full particle simulations with different ion to electron mass ratio
Microinstabilities perpendicular collisionless shocks comparison of full particle simulations electron mass ratio Plasma Physics
2012/4/24
A full particle simulation study is carried out for studying microinstabilities generated at the shock front of perpendicular collisionless shocks. The structure and dynamics of shock waves are determ...

Marginally ratio close binary V1191 Cyg
2011/9/27
In this study, we present photometric and spectroscopic variations of the extremely small mass ratio ($q\simeq 0.1$) late-type contact binary system \astrobj{V1191 Cyg}. The parameters for the hot and...
The impact of realistic models of mass segregation on the event rate of extreme-mass ratio inspirals and cusp re-growth
realistic models mass segregation the event rate
2011/1/11
One of the most interesting sources of gravitational waves (GWs) for LISA is the inspiral of compact objects on to a massive black hole (MBH), commonly referred to as an "extreme-mass ratio inspiral" ...
Space-time variation of the electron-to-proton mass ratio in a Weyl model
Space-time variation the electron-to-proton mass ratio
2011/1/13
We consider a phenomenological model where the effective fermion masses depend on the local value of Weyl tensor as a possible explanation for the recent data indicating a space-time variation of the...
Resonant recoil in extreme mass ratio binary black hole mergers
Resonant recoil extreme mass ratio binary black hole mergers
2010/12/20
The inspiral and merger of a binary black hole system generally leads to an asymmetric distribution of emitted radiation, and hence a recoil of the remnant black hole directed opposite to the net line...

Intermediate-mass-ratio-inspirals Einstein Telescope Parameter estimation errors
2010/11/16
We explore the precision with which the Einstein Telescope (ET) will be able to measure the
parameters of intermediate–mass–ratio inspirals (IMRIs), i.e., the inspirals of stellar mass compact object...

The Effect of Massive Perturbers on Extreme Mass-Ratio Inspiral Waveforms
Galaxy Astrophysics (astro-ph.GA) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
Extreme mass ratio inspirals, in which a stellar-mass object merges with a supermassive black hole, are prime sources for space-based gravitational wave detectors because they will facilitate tests of...
Intermediate Mass Ratio Black Hole Binaries: Numerical Relativity meets Perturbation Theory
