Einstein's aborted attempt at a dynamic steady-state universe
Harry Nussbaumer
In June 1930 Einstein visited Cambridge where he stayed with Eddington who had just shown that Einstein's supposedly static universe of 1917 was not stable. This forced Einstein to…
Einstein's conversion from his static to an expanding universe
Harry Nussbaumer
In 1917 Einstein initiated modern cosmology by postulating, based on general relativity, a homogeneous, static, spatially curved universe. To counteract gravitational contraction h…
Slipher's redshifts as support for de Sitter's model and the discovery of the dynamic universe
Harry Nussbaumer
Of the first two relativistiv world models, only the one by de Sitter predicted redshifted spectra from far away astronomical objects. Slipher's redshifts therefore seemed to arbit…
Who discovered the expanding universe?
Harry Nussbaumer, Lydia Bieri
Who discovered the expanding universe? Was it Hubble, or Lemaître, or was it just the end result of a long series of investigations? In this article we summarise the main steps and…
High resolution spectroscopy of symbiotic stars. VI. Orbital and stellar parameters for AR Pav
H. Schild, T. Dumm, U. Muerset +3
We present new dynamical parameters of the AR Pav binary system. Ourobservations consist of a series of high resolution optical/NIR spectra from which we derive the radial velocity…
