Shear and Vorticity in a Combined Einstein-Cartan-Brans-Dicke Inflationary Lambda-Universe
Marcelo Samuel Berman
A combined BCDE (Brans-Dicke and Einstein-Cartan) theory with lambda-term is developed through Raychaudhuri's equation, for inflationary scenario. It involves a variable cosmologic…
The Pioneer Anomaly and a Machian Universe
Marcelo Samuel Berman
We discuss astronomical and astrophysical evidence, which we relate to the principle of zero-total energy of the Universe, that imply several relations among the mass M, the radius…
Determining the Nature of the SS 433 Binary Using an X-ray Spectrum During Eclipse
Laura A. Lopez, Herman L. Marshall, Claude R. Canizares +2
We test the physical model of the relativistic jets in the galactic X-ray binary SS 433 proposed in our previous paper using additional observations from the Chandra High Energy Tr…
Temperature inversion on the surface of externally heated optically thick multigrain dust clouds
Dejan Vinkovic
It was recently discovered that the temperature in the surface layer of externally heated optically thick gray dust clouds increases with the optical depth for some distance from t…
Spherical Accretion
Re'em Sari, Peter Goldreich
We compare different examples of spherical accretion onto a gravitating mass. Limiting cases include the accretion of a collisionally dominated fluid and the accretion of collision…
Primordial Helium Abundance: A Reanalysis of the Izotov-Thuan Spectroscopic Sample
Masataka Fukugita, Masahiro Kawasaki
A reanalysis is made for the helium abundance determination for the Izotov-Thuan (2004) spectroscopic sample of extragalactic H II regions. We find that the effect of underlying st…
