On binary pulsars and the force of gravity
Davor Palle
The energy-momentum budget of the astrophysical systems can be studied by the exact local conservation equation derived by Landau and Lifshitz. We show that a similar equation is v…
Oscillation frequencies and mode lifetimes in alpha Centauri A
Timothy R. Bedding, Hans Kjeldsen, R. Paul Butler +5
We analyse our recently-published velocity measurements of alpha Cen A (Butler et al. 2004). After adjusting the weights on a night-by-night basis in order to optimize the window f…
Hipparcos period-luminosity relations for Miras and semiregular variables
T. R. Bedding, A. A. Zijlstra
We present period-luminosity diagrams for nearby Miras and semiregulars, selecting stars with parallaxes better than 20 per cent and well-determined periods. Using K-band magnitude…
A Cyclical Baryonic Big Bang Explains the Universe
David E. Rosenberg
Our universe has multiple examples of unexplained gravitational losses in black holes and neutron stars. The smallest black holes of about 4 solar masses means the maximum baryon d…
Quantum Correction for our Big Bang Bouncing Universe
David E. Rosenberg
Our Universe has multiple examples of unexplained gravitational losses in black holes and neutron stars. As all of the space is squeezed out, nucleons are not easily compressible f…
A survey of debris trails from short-period comets
William T. Reach, Michael S. Kelley, Mark V. Sykes
We observed 34 comets using the 24 micron camera on the Spitzer Space Telescope. Each image contains the nucleus and covers at least 10^6 km of each comet's orbit. Debris trails du…
