Tidal Disruption of Planetesimals from an Eccentric Debris Disk Following a White Dwarf Natal Kick
Tatsuya Akiba, Selah McIntyre, Ann-Marie Madigan
The surfaces of many white dwarfs are polluted by metals, implying a recent accretion event. The tidal disruption of planetesimals is a viable source of white dwarf pollution and o…
How to Flip a Bar
Angela Collier, Ann-Marie Madigan
Galactic bars, made up of elongated and aligned stellar orbits, can lose angular momentum via resonant torques with dark matter particles in the halo and slow down. Here we show th…
Anisotropic Star Clusters around Recoiling Supermassive Black Holes
Tatsuya Akiba, Ann-Marie Madigan
Gravitational wave recoil kicks from merging supermassive black hole binaries can have a profound effect on the surrounding stellar population. In this work, we study the dynamic a…
Steeper Scattered Disks Buckle Faster
Alexander Zderic, Ann-Marie Madigan
Disks of low-mass bodies scattered by giant planets to large semi-major axis and constant periapsis orbits are vulnerable to a buckling instability. This instability exponentially…
Magnetized Gas Clouds can Survive Acceleration by a Hot Wind
Michael McCourt, Ryan M. O'Leary, Ann-Marie Madigan +1
We present three-dimensional magnetohydrodynamic simulations of magnetized gas clouds accelerated by hot winds. We initialize gas clouds with tangled internal magnetic fields and s…
The Galactic Center cloud G2 and its gas streamer
Oliver Pfuhl, Stefan Gillessen, Frank Eisenhauer +10
We present new, deep near-infrared SINFONI @ VLT integral field spectroscopy of the gas cloud G2 in the Galactic Center, from late summer 2013 and spring 2014. G2 is visible in rec…
