Wrinkles in Time. II. Stellar Age Trends in Kinematic Signatures from Transient Spiral Structure
Amy Smock, Kathryne J. Daniel, Rayna Rampalli +4
Spiral arms in the disks of galaxies like the Milky Way can generate kinematic signatures, which appear as ridges or wrinkles in action space. Such signatures have proven difficult…
The dark matter wake of a galactic bar revealed by multichannel Singular Spectral Analysis
Jason A. S. Hunt, Michael S. Petersen, Martin D. Weinberg +7
The Milky Way is known to contain a stellar bar, as are a significant fraction of disc galaxies across the universe. Our understanding of bar evolution, both theoretically and thro…
The Orbital Eccentricities of Planets in the Kinematic Thin and Thick Galactic Disks
Sheila Sagear, Sarah Ballard, Kathryne J. Daniel +4
The orbital eccentricity distribution of exoplanets is shaped by a combination of dynamical processes, reflecting both formation conditions and long-term evolution. Probing the orb…
PECCARY: A novel approach for characterizing orbital complexity, stochasticity, and regularity
Sóley Ã. Hyman, Kathryne J. Daniel, David A. Schaffner
Permutation Entropy and statistiCal Complexity Analysis for astRophYsics (PECCARY) is a computationally inexpensive, statistical method by which any time-series can be characterize…
