These notes introduce and review some of the physical principles underlying the theory of astrophysical accretion, emphasizing the central roles of angular momentum transport, angular momentum loss, and radiative cooling in determining the structure and evolution of accretion flows. Additional topics covered include the effective viscous theory of thin disks, classical instabilities of disk structure, the evolution of warped or eccentric disks, and the basic properties of waves within disks.

  1. Observing planetary gaps in the gas of debris disks

    astro-ph.EP 2024-11 conditional novelty 7.0 of 10

    Giant planets in the low-density CO gas of debris disks can open gaps that fall below ALMA's detection threshold, making planetary gaps observable in the gas and offering a new indirect exoplanet detection channel.

  2. Puffed-up Edges of Planet-opened Gaps in Protoplanetary Disks. II. The Role of the Planet's Orbital Eccentricity

    astro-ph.EP 2026-07 conditional novelty 6.0 of 10

    Eccentric gap-opening planets enhance dust lofting at gap edges via stronger meridional circulation, make gaps leaky to dust, and produce larger, wider pebble rings than circular planets.

  3. A visual approach to global accretion disk instabilities

    astro-ph.GA 2025-07 conditional novelty 6.0 of 10

    Linear superpositions of SARI eigenmodes in global disk models produce spiral, vertically displaced field structures and alpha values in the 0.007 to 0.08 range without nonlinear saturation.
