    Asymptotic solutions for a relativistic formulation of the generalized nonextensive Thomas-Fermi model by Van Gorder, R, Lowry, V

    Published 2016
    “…While this generalized model has potential application to neutron stars and in understanding the screening process in relativistic dense astrophysical plasmas, there has not been a study on the behavior of the Thomas-Fermi potential φ(x) due to nonextensive statistical mechanics and relativistic effects. …”

    Thomson scattering from near-solid density plasmas using soft X-ray free electron lasers by Hoell, A, Bornath, T, Cao, L, Doeppner, T, Duesterer, S, Foerster, E, Fortmann, C, Glenzer, S, Gregori, G, Laarmann, T, Meiwes-Broer, K, Przystawik, A, Radcliffe, P, Redmer, R, Reinholz, H, Roepke, G, Thiele, R, Tiggesbaeumker, J, Toleikis, S, Truong, N, Tschentscher, T, Uschmann, I, Zastrau, U

    Published 2007
    “…The plasma region of interest marks the transition from an ideal plasma to a correlated and degenerate many-particle system and is of current interest, e.g., in ICF experiments or laboratory astrophysics. Plasma diagnosis of such plasmas is a longstanding issue which is addressed here using a pump-probe scattering experiment to reveal the collective electron plasma mode (plasmon) using the high-brilliance radiation to probe the plasma. …”

    Nonlinear mirror instability by Rincon, F, Schekochihin, A, Cowley, S

    Published 2014
    “…Slow dynamical changes in magnetic-field strength and invariance of the particles' magnetic moments generate ubiquitous pressure anisotropies in weakly collisional, magnetized astrophysical plasmas. This renders them unstable to fast, small-scale mirror and firehose instabilities, which are capable of exerting feedback on the macroscale dynamics of the system. …”

    Convective and Rotational Stability of a Dilute Plasma by Balbus, S

    Published 2001
    “…Previous studies have generally been based upon the classical H{\o}iland criteria, which are inappropriate for magnetized, dilute astrophysical plasmas. In sharp contrast to recent claims in the literature, the new stability criteria demonstrate that marginal flow stability is not a fundamental property of accreting plasmas thought to be associated with low luminosity X-ray sources.…”
