On quantum ergodicity for vector bundles
Ulrich Bunke, Martin Olbrich
In the present paper we develop a framework in which questions of quantum ergodicity for operators acting on sections of hermitian vector bundles over Riemannian manifolds can be s…
Properties of Young Massive Cluster Derived from Photometry
U. Fritze-v. Alvensleben
I will show that photometry -- if extending over a reasonable choice of passbands -- can give fairly precise information about young star clusters and their evolutionary state. Opt…
Star Formation in Galaxy Mergers: Scaling up a universal process or a violent mode of SF?
U. Fritze-v. Alvensleben
I briefly review some measures of star formation rates in galaxies and discuss their respective uncertainties before outlining the range of star formation rates encountered in star…
HS2237+8154: On the onset of mass transfer or entering the period gap?
B. T. Gaensicke, S. Araujo-Betancor, H. -J. Hagen +4
We report follow-up observations of a new white dwarf/red dwarf binary HS2237+8154, identified as a blue variable star from the Hamburg Quasar Survey. Ellipsoidal modulation observ…
