Open clusters are known as excellent tools for various topics in Galactic research. For example, they allow accurately tracing the chemical structure of the Galactic disc. However, the metallicity is…
The Gaia-ESO Public Spectroscopic Survey
- G. Gilmore, S. Randich, T. Zwitter
- Physics
- 1 March 2012
The Gaia-ESO Public Spectroscopic Survey has begun and will obtain high quality spectroscopy of some 100000 Milky Way stars, in the field and in open clusters, down to magnitude 19, systematically ...
On the metallicity of open clusters - II. Spectroscopy
- U. Heiter, C. Soubiran, M. Netopil, E. Paunzen
- Physics
- 10 November 2013
Context. Open clusters are an important tool for studying the chemical evolution of the Galactic disk. Metallicity estimates are available for about ten percent of the currently known open clusters.…
On the metallicity of open clusters - I. Photometry
- E. Paunzen, U. Heiter, Laboratoire d'astrophysique de Bordeaux
- Physics
- 1 July 2010
Context. Metallicity is one of four free parameters typically considered when fitting isochrones to the cluster sequence. Unfortunately, this parameter is often ignored or assumed to be solar in most…
Peranso - Light curve and period analysis software
- E. Paunzen, T. Vanmunster
- Chemistry
- 17 February 2016
An introduction to Peranso and its functionality is given, which offers a complete set of powerful light curve and period analysis functions to work with large astronomical data sets.
Chemically peculiar stars and their temperature calibration
- M. Netopil, E. Paunzen, H. Maitzen, P. North, S. Hubrig
- Physics
- 30 September 2008
Aims. The determination of effective temperature for chemically peculiar (CP) stars by means of photometry is a sophisticated task due to their abnormal colours. Standard calibrations for normal…
A new catalogue of Stroemgren-Crawford uvbybeta photometry
- E. Paunzen
- Physics
- 15 June 2015
A new all-sky catalogue of all available uvbybeta measurements from the literature was generated. The uvbybeta photometric system is widely used for the study of various Galactic and extragalactic…
New variable chemically peculiar stars identified in the Hipparcos archive
- E. Paunzen, H. Maitzen
- Physics
- 1 November 1998
Since variability of chemically peculiar (CP) stars plays an important role for the astrophysical explanation of their outstanding behaviour, we have identified new variable CP stars listed in…
On the current status of open-cluster parameters
- E. Paunzen, M. Netopil
- Physics
- 18 July 2006
We aim to characterize the current status of knowledge on the accuracy of open-cluster parameters such as the age, reddening and distance. These astrophysical quantities are often used to study the…
Updated parameters of 1743 open clusters based on Gaia DR2
- W. Dias, H. Monteiro, L. Villela
- Geology
- 23 March 2021
In this study we follow up our recent paper (Monteiro et al. 2020) and present a homogeneous sample of fundamental parameters of open clusters in our Galaxy, entirely based onGaiaDR2 data. We used…
