We present a comprehensive study of s-process nucleosynthesis in 15, 20, 25, and 30 $\msun$ stellar models having solar-like initial
The exact solution in the LTB model with $f^2 = 1$, $Ξ\ne 0$ is studied. The initial conditions for the
Alignment of velocity and acceleration before shell crossing, and later misalignment are used to define velocity contrast, an indicator of
Isospin breaking correction to the $ΞI = {1/2}$ decay of $K\toΟΟ$ generates a large enough contribution to $Ξ΅'$ through an
We inquire if the total decay rate of neutral vector mesons can contain relevant off-shell contributions from the triangle anomaly.
We re-examine the recent proposal of Rastelli, Sen and Zwiebach on the tachyon fluctuation of the vacuum string field theory
We investigate the gravitational behavior of spherical domain walls (bubbles) arising during the phase transitions in the early Universe. In
We investigate the dynamics of self-gravitating, spherically-symmetric distributions of fluid through numerical means. In particular, systems involving neutron star models
A 100ks XMM-Newton observation of the nearby Seyfert 2 galaxy Mrk 3 offers a unique opportunity to explore the complexity
A relativistic quantized particle model avoids difficulties through (1) a Hamiltonian undecomposable into H=H(0)+H(I), (2) a separation of the evolution
I propose that the properties of QCD perturbation theory should be investigated when the boundary state (`perturbative vacuum') at $t=
In the `condensed phase' of effective quantum field theories one expects deviations from exact Lorentz invariance at ultralow momenta |
I modify the quasilocal energy formalism of Brown and York into a purely Hamiltonian form. As part of the reformulation,
We investigate the pulsation-phase dependent properties of the circumstellar dust shell (CDS) of the OH/IR star OH104.9+2.4 based on radiative
We discovered independently the shell-type supernova remnant G12.82-0.02, recently reported by Brogan et al. (2005), which is coincident with the
We propose that some of the unidentified Galactic plane (-10 degrees < b < 10 degrees) sources listed in the
We show that a bound system in momentum space can be treated like a gas of free elementary constituents and
The surface chemical composition of this remarkable star shows that it is hydrogen-deficient, carbon-rich and enriched in the light s-process
The OH main line masers in circumstellar shells were observed with astrometric VLBI in order to accurately determine the position
In this thesis I review cosmological and astrophysical exact models for Randall-Sundrum-type braneworlds and their physical implications. I present new
We present a study of the radio environment of the gamma-ray source 3EG J1828+0142. This source presents a very high
The expectation value of the angular part of the spin-orbit-coupling (SOC) operator $<l\cdot s>$ and the branching ratio for the
An elementary constituent-quark (CQ) model of mesons was previously presented. In this paper, we continue research into a study of
We report broad-band X-ray measurements of the Be star Gamma Cassiopeiae by the BeppoSAX X-ray astronomy satellite. The observations took
