Disrupted Wide Binaries as Dynamical Probes of Galactic Structure
Tomer D. Yavetz
Many of the stars in the Galaxy were formed in binary systems. The widest of these can eventually become disrupted due to a combination of kicks from passing stars and the Galactic…
Fuzzy dark matter dynamics in tidally perturbed dwarf spheroidal galaxy satellites
Axel Widmark, Tomer D. Yavetz, Xinyu Li
Fuzzy dark matter (FDM) has dynamical properties that differ significantly from cold dark matter (CDM). These dynamical differences are strongly manifested on the spatial scale of…
Stream Fanning and Bifurcations: Observable Signatures of Resonances in Stellar Stream Morphology
Tomer D. Yavetz, Kathryn V. Johnston, Sarah Pearson +2
Recent observations have revealed a trove of unexpected morphological features in many of the Milky Way's stellar streams. Explanations for such features include time-dependent def…
Construction of Wave Dark Matter Halos: Numerical Algorithm and Analytical Constraints
Tomer D. Yavetz, Xinyu Li, Lam Hui
We present a wave generalization of the classic Schwarzschild method for constructing self-consistent halos -- such a halo consists of a suitable superposition of waves instead of…
Separatrix Divergence of Stellar Streams in Galactic Potentials
Tomer D. Yavetz, Kathryn V. Johnston, Sarah Pearson +2
Flattened axisymmetric galactic potentials are known to host minor orbit families surrounding orbits with commensurable frequencies. The behavior of orbits that belong to these orb…
Oscillations and Random Walk of the Soliton Core in a Fuzzy Dark Matter Halo
Xinyu Li, Lam Hui, Tomer D. Yavetz
A Fuzzy Dark Matter (FDM) halo consists of a soliton core close to the center and an NFW-like density profile in the outer region. Previous investigations found that the soliton co…
Why do Earth satellites stay up?
Scott Tremaine, Tomer Yavetz
Satellites in low Earth orbits must accurately conserve their orbital eccentricity, since a decrease in perigee of only 5-10% would cause them to crash. However, these satellites a…
