This contribution briefly discusses some new theoretical results for the properties of charmonium, especially the "higher charmonium" states above open-charm threshold. In particul…
Measurement method for the nuclear anapole moment of laser trapped alkali atoms
E. Gomez, S. Aubin, G. D. Sprouse +2
Weak interactions within a nucleus generate a nuclear spin dependent parity violating electromagnetic moment; the anapole moment. In heavy nuclei, the anapole moment is the dominan…

Subluminous O stars from the ESO Supernova Progenitor Survey - Observation versus Theory
A. Stroeer, U. Heber, T. Lisker +2
The ESO Supernova Progenitor Survey (SPY) has identified 58 (mostly helium-rich) subluminous O stars. We use the Balmer line strength to distinguish sdO from He-sdO (no Balmer line…
