Apsidal Clustering following the Inclination Instability
Alexander Zderic, Angela Collier, Maria Tiongco +1
Disks of low-mass bodies on high-eccentricity orbits in near-Keplerian potentials can be dynamically unstable to buckling out of the plane. In this letter, we present -body simu…
Violent Buckling Benefits Galactic Bars
Angela Collier
Galactic bars are unstable to a vertical buckling instability which heats the disk and in some cases forms a boxy/peanut shaped bulge. We analyze the buckling instability as an app…
Stellar Bars in Counter-Rotating Dark Matter Halos: The Role of Halo Orbit Reversals
Angela Collier, Isaac Shlosman, Clayton Heller
Disk galaxies can exchange angular momentum and baryons with their host dark matter (DM) halos. These halos possess internal spin, `lambda', which is insignificant rotationally but…
Dark Matter Bars in Spinning Halos
Angela Collier, Isaac Shlosman, Clayton Heller
We study nonlinear response of spinning dark matter (DM) halos to dynamic and secular evolution of stellar bars in the embedded galactic disks, using high-resolution numerical simu…
Characterising exoplanets and their environment with UV transmission spectroscopy
L. Fossati, V. Bourrier, D. Ehrenreich +36
Exoplanet science is now in its full expansion, particularly after the CoRoT and Kepler space missions that led us to the discovery of thousands of extra-solar planets. The last de…
