Color Transparency at ELFE
Bernard Pire, Ingo Sick
We review the presentations given in the Color Transparency parallel session held during the second ELFE workshop.
Microlensing Optical Depth of the COBE Bulge
N. Bissantz, P. Englmaier, J. Binney +1
We examine the left-right asymmetry in the cleaned COBE/DIRBE near-infrared data of the inner Galaxy and show (i) that the Galactic bar is probably not seen very nearly end-on, and…
Two modes of gas flow in a single barred galaxy
Peter Englmaier, Ortwin Gerhard
We investigate stationary gas flows in a fixed, rotating barred potential. The gas is assumed to be isothermal with an effective sound speed c_s, and the equations of motion are so…
The evidence for the long distance scale with H_0<65
Allan Sandage, G. A. Tammann
The status of the determination of the Hubble constant is reviewed, setting out the evidence for the long distance scale with H_0=55+/-5. In parallel, various precepts said to favo…
Focussing in on H_0
G. A. Tammann, M. Federspiel
Six independent methods yield a Virgo cluster modulus of (m-M)=31.66+/- 0.08. This inserted into the Hubble diagram of clusters, whose relative distances to the Virgo cluster are k…
Strangeness in the nucleon and the ratio of proton-to-neutron neutrino-induced quasi-elastic yield
E. Kolbe, S. Krewald, H. Weigel
The electroweak form factors of the nucleon as obtained within a three flavor pseudoscalar vector meson soliton model are employed to predict the ratio of the proton and neutron yi…
Polarimetry of the Type Ia Supernova SN 1996X
Lifan Wang, J. Craig Wheeler, Peter Hoeflich
We present broad-band and spectropolarimetry of the Type Ia SN 1996X obtained on April 14, 1996 (UT), and broad-band polarimetry of SN 1996X on May 22,1996, when the supernova was…
Maximum Brightness and Post-Maximum Decline of Light Curves of SN~Ia: A Comparison of Theory and Observations
P. Höflich, A. Khokhlov, J. C. Wheeler +3
We compare the observed correlations between the maximum brightness, postmaximum decline rate and color at maximum light of Type Ia supernovae (SN Ia) with model predictions. The o…
The photometric structure of the inner Galaxy
James Binney, Ortwin Gerhard, David Spergel
The light distribution in the inner few kiloparsecs of the Milky Way is recovered non-parametrically from a dust-corrected near-infrared COBE/DIRBE surface brightness map of the in…
Uncertainties In Direct Neutron Capture Calculations Due To Nuclear Structure Models
T. Rauscher, K. -L. Kratz, H. Oberhummer +3
The prediction of cross sections for nuclei far off stability is crucial in the field of nuclear astrophysics. For spherical nuclei close to the dripline the statistical model (Hau…
Applicability Of The Hauser-Feshbach Approach For The Determination of Astrophysical Reaction Rates
T. Rauscher, F. -K. Thielemann, K. -L. Kratz
Nuclear Astrophysics requires the knowledge of reaction rates over a wide range of nuclei and temperatures. In recent calculations the nuclear level density - as an important ingre…
Neutron-induced nucleosynthesis
H. Oberhummer, H. Herndl, T. Rauscher +1
Neutron--induced nucleosynthesis plays an important role in astrophysical scenarios like in primordial nucleosynthesis in the early universe, in the s--process occurring in Red Gia…
A fresh look into pulsating PG1159 stars
Alfred Gautschy
To improve the understanding of the pulsational instabilities of some of the PG1159-type pre-white dwarfs we performed detailed stability analyses on helium star evolutionary model…
Neutrino induced transitions between the ground states of the A=12 triad
J. Engel, E. Kolbe, K. Langanke +1
Neutrino induced reactions on C, an ingredient of liquid scintillators, have been studied in several experiments. We show that for currently available neutrino energies, $E_…
Multiple electromagnetic electron positron pair production in relativistic heavy ion collisions
Adrian Alscher, Kai Hencken, Dirk Trautmann +1
We calculate the cross sections for the production of one and more electron-positron pairs due to the strong electromagnetic fields in relativistic heavy ion collisions. Using the…
Direct Hopf Bifurcation in Parametric Resonance of Hybridized Waves
Franz-Josef Elmer
We study parametric resonance of interacting waves having the same wave vector and frequency. In addition to the well-known period-doubling instability we show that under certain c…
Dynamics of the Bar at the Galactic Centre
Ortwin Gerhard
The now substantial evidence for a rotating bar in the inner Galaxy and its dynamical implications are reviewed.
H_0 from HST
G. A. Tammann, L. Labhardt, M. Federspiel +4
HST has so far provided Cepheid distances to nine galaxies. Although not sufficient yet to determine the distance of the extended Virgo cluster, they are decisive for the distance…
Astrophysical Reaction Rates for B(p,)Be and B(p,)Be From a Direct Model
T. Rauscher, G. Raimann
The reactions B(p,)Be and B(p,)Be are studied at thermonuclear energies using DWBA calculations. For both reactions, transitions to the ground state…
The Nuclear Level Density and the Determination of Thermonuclear Rates for Astrophysics
T. Rauscher, F. -K. Thielemann, K. -L. Kratz
The prediction of cross sections for nuclei far off stability is crucial in the field of nuclear astrophysics. In recent calculations the nuclear level density -- as an important i…
Small Denominators, Frequency Operators, and Lie Transforms for Nearly-Integrable Quantum Spin Systems
Thomas Gramespacher, Stefan Weigert
Based on the previously proposed notions of action operators and of quantum integrability, frequency operators are introduced in a fully quantum-mechanical setting. They are concep…
Equivalent Photon Approach to Simultaneous Excitation in Heavy Ion Collision
Kai Hencken, Dirk Trautmann, Gerhard Baur
We apply the Equivalent Photon Approximation to calculate cross sections for the simultaneous excitation of two heavy ions in relativistic collisions. We study especially the excit…
