  Major scientific questions and research opportunities are described on 10
unprioritized plasma astrophysics topics: (1) magnetic reconnection, (2)
collisionless shocks and particle acceleration, (3) waves and turbulence, (4)
magnetic dynamos, (5) interface and shear instabilities, (6) angular momentum
transport, (7) dusty plasmas, (8) radiative hydrodynamics, (9) relativistic,
pair-dominated and strongly magnetized plasmas, (10) jets and outflows. Note
that this is a conference report from a Workshop on Opportunities in Plasma
Astrophysics (WOPA, https://w3.pppl.gov/conferences/2010/WOPA/) in January
2010, that attracted broad representation from the community and was supported
by the U.S. Department of Energy, National Aeronautics and Space
Administration, National Science Foundation, American Physical Society's
Topical Group for Plasma Astrophysics and Division of Plasma Physics, and
Center for Magnetic Self-Organization in Laboratory and Astrophysical Plasmas.
Although there has been much planning and many developments in both science and
infrastructure since the report was written, most of the motivation,
priorities, problems and technical challenges discussed therein remain
unaddressed and are relevant at the time of posting.
