Simple stellar population models including blue stragglers

von Yu Xin


The BS-SSP models cover the wavelength range from 91 angstrom to 160 micron, ages from 0.1 to 20 Gyr and metallicities Z=0.0004, 0.004, 0.008, 0.02 and 0.05. The BS-SSP models are constructed as increments to the Bruzual & Charlot (2003) standard SSP models using the Padova1994 isochrones and the Lejeune et al. (1997) stellar spectra. Thus they can be used directly in evolutionary population synthesis studies as replacement of BC03 for the same parameter coverage.

IGIMF data tables

von Jan Pflamm-Altenburg


This package i) provides a tool for calculating the integrated galactic initial mass function (IGIMF) and fitting it by a multi-part power law, and ii) contains the IGIMF-data tables used in Pflamm-Altenburg, Weidner & Kroupa (2009).

Primordial gas expulsion data

von Holger Baumgardt


This archive contains data on star clusters evolving under residual gas expulsion, obtained through a series of direct N-body simulations. Given are the lagrangian radii for bound and unbound stars and the fraction of bound stars as a function of time for all simulated clusters.

Leiden/Argentine/Bonn (LAB) Galactic H i Survey

The LAB survey contains the final data release of observations of 21-cm emission from Galactic neutral hydrogen over the entire sky, merging the Leiden/Dwingeloo Survey (LDS, Hartmann & Burton 1997) of the sky north of -30° with the Instituto Argentino de Radioastronomía Survey (IAR, Arnal et al. 2000 and Bajaja et al. 2005) of the sky south of -25°.
