A virial theorem for rotating charged perfect fluids in general relativity

open access: yes, 2003
We obtain an exact form of the virial theorem in general relativity, which is sufficiently general to be applied to charged, conducting, rotating perfect fluids in electromagnetic and gravitational fields.

The virial theorem and the atmosphere [PDF]

open access: yes, 2003
In our atmosphere, most of the energy resides as internal energy, U, and gravitational energy P, and the proportionality U/P = cV /R = 5/2 is maintained in an air column provided there is hydrostatic equilibrium.

Closed-Shell and Chemical Bonding Effects are Almost Negligible in Two-Digit Z Elements

open access: yesCHIMIA, 1988
In an atom, the total binding energy of Z electrons is close to EGG = Z2.4 rydberg, with observed (available up to Z = 17) and calculated non-relativistic values decreasing from 1.036 EGG for Z = 5 to 0.996 EGG for Z = 90; and relativistic values going ...

Dynamical Structure of NGC 4486 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1987
The peculiar elliptical (EOp) galaxy NGC 4486 and two KOII comparison stars HR5450, HR6935 were observed spectroscopically using the 74-inch telescope and Image Tube at Mt. Stomlo Observatory.

The Radial Acceleration Relation in Galaxies and Clusters from a Two-component, Virial-motivated Framework

open access: yesThe Astrophysical Journal
We present a comparative analysis of acceleration data for gravitational systems drawn from multiple observational sources, including (i) early-type galaxies (ETGs), (ii) brightest cluster galaxies (BCGs) and galaxy clusters, and (iii) weak gravitational

Reflections on dipolar quantum fluids

open access: yesComptes Rendus. Physique
We present a thermodynamic description of ultracold gases with dipolar interactions which properly accounts for the long-range nature and broken rotation invariance of the interactions.

The virial theorem and the Price equation [PDF]

open access: yes
We observe that the time averaged continuous Price equation is identical to the positive momentum virial theorem, and we discuss the applications and implications of this connection.13 ...

Virial theorem in clusters of galaxies with MOND

open access: yes, 2022
A specific modification of Newtonian dynamics known as MOND has been shown to reproduce the dynamics of most astrophysical systems at different scales without invoking non-baryonic dark matter (DM).
