Generalized virial theorem in Palatini $f(R)$ gravity
We use the collision-free Boltzmann equation in Palatini $f({\mathcal{R}})$ gravity to derive the virial theorem within the context of the Palatini approach.

Three-body resonance states just below the antiproton and hydrogen dissociation threshold
We analyze two shallow resonance states below the antiproton hydrogen dissociation threshold with a non-adiabatic three-body calculation. Rearrangement correlation between initial channel and protonium formation channel is explicitly included in the ...

Clausius/Cosserat/Maxwell/Weyl Equations: The Virial Theorem Revisited [PDF]
In 1870, R. Clausius found the virial theorem which amounts to introduce the trace of the stress tensor when studying the foundations of thermodynamics, as a way to relate the absolute temperature of an ideal gas to the mean kinetic energy of its ...

The Virial Theorem for Retarded Gravity
The general theory of relativity (GR) is symmetric under smooth coordinate transformations also known as diffeomorphisms. The general coordinate transformation group has a linear subgroup denoted the Lorentz group of symmetry which is maintained also in the weak field approximation to GR.

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

Reflections on dipolar quantum fluids
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.

Line-of-Sight Mass Estimator and the Masses of the Milky Way and Andromeda Galaxy
The total mass of a galaxy group, such as the Milky Way (MW) and the Andromeda Galaxy (M 31), is typically determined from the kinematics of satellites within their virial zones. Bahcall and Tremaine (1981) proposed the v2r estimator as an alternative to
