Gravitational instability in partially ionized plasmas: A two-fluid approach
A. P. Misra, V. Krishan
We propose a new two-fluid model for a partially ionized magnetoplasma under gravity, in which electrons and neutrals are treated as a single fluid, while singly charged positive i…
Coupling of Alfvén and magnetosonic waves in rotating Hall magnetoplasmas
A. P. Misra, R. Dey, V. Krishan
We study the linear theory of magnetohydrodynamic (MHD) waves, namely the Alfv{é}n and the fast and slow magnetosonic modes in a rotating Hall-MHD plasma with the effects of the ob…
Kolmogorov Dissipation scales in Weakly Ionized Plasmas
V. Krishan, Z. Yoshida
In a weakly ionized plasma, the evolution of the magnetic field is described by a "generalized Ohm's law" that includes the Hall effect and the ambipolar diffusion terms. These ter…
Mean-field dynamo in partially ionized plasmas-I
V. Krishan, R. T. Gangadhara
There are several astrophysical situations where one needs to study the dynamics of magnetic flux in partially ionized turbulent plasmas. In a partially ionized plasma the magnetic…
Relationship between Horizontal Flow Velocity and Cell Lifetime for Supergranulation
U. Paniveni, V. Krishan, Jagdev Singh +1
A study of 50 supergranular cells obtained from SOHO Dopplergrams was undertaken in order to investigate the relationship between the lifetime () and the horizontal flow velocit…
