Spectral analysis by means of NLTE model atmospheres has presently arrived at a high level of sophistication. High-resolution spectra of central stars of planetary nebulae can be reproduced in detail from the infrared to the X-ray wavelength range. In the case of LSV+46◦21, the exciting star of Sh 2−216, we demonstrate the state-of-the-art in the determination of photospheric properties like, e...

Astronomy is facing a revolution in data collection, storage, analysis, and interpretation of large datasets. The data volumes here are several orders of magnitude larger than what astronomers and statisticians are used to dealing with, and the old methods simply do not work. The National Virtual Observatory (NVO) initiative has recently emerged in recognition of this need and to federate numer...

Within the framework of the German Astrophysical Virtual Observatory (GAVO), we provide synthetic spectra, simulation software for the calculation of NLTE model atmospheres, as well as necessary atomic data. This will enable a VO user to directly compare observation and model-atmosphere spectra on three levels: The easiest and fastest way is the use of our pre-calculated flux-table grid in whic...

Advanced visualization tools can help the researcher in investigating and extracting information from complex data. VisIVO and VisIVOServer, are novel open-source graphics applications that use high-performance multidimensional visualization techniques for astrophysical data exploration and analysis. They support the standards defined by the International Virtual Observatory Alliance in order t...

Global economy is undergoing a recession phase that had made competition tougher and imposed new business framework. Businesses have to shift from the classical management approaches to an Intelligent Project Based Organization Model (IPBOM) that provides flexibility and agility. IPBOM is intended to reinforce the proven advantages of Project Based Organization (PBO) by the use of suitable Ente...

The Space Physics Archive Search and Extract (SPASE) project has developed an information model for interoperable access and retrieval of data within the Heliophysics (also known as space and solar physics) science community. The diversity of science data archives within this community has led to the establishment of many virtual observatories to coordinate the data pathways within Heliophysics...

In this paper is described the system that controls the connected devices in a subsea observatory. The control system is constantly monitoring the internal and external components of the observatory detecting operating faults and acting automatically in consequence.

An architectural framework for implementing a distributed observatory control system is presented here. It has been partially realized and tested in the 2m optical and infrared Observatory at Pune, India.
