PublicationDecay rates of sunspot groups from 1874 to 1976
The global behaviour and fine structure of the distribution of sunspot decay rates from activity cycle 13 to 20 are presented. It is shown that the distribution...

PublicationDeriving Star Formation Histories: Evolutionary or Population Synthesis Codes versus Color-Magnitude Diagrams
The goal of this project is to analyze the integrated-light spectrum of a region in the LMC bar, for which HST images are already available yielding color...

PublicationFaint Features of Interacting Galaxies Revealed by the Digital Coaddition of 13 Tech-Pan Films of the Virgo Cluster
We have digitally coadded APM scans of 13 Kodak TechPan films of the SE region of the Virgo Cluster of galaxies. The ~6.2°×6.2° field of the R-band films...
