Information Technology (IT) today has found so many applications in astronomy , that we may speak of an electronic`Astronomical Information Infrastructure' (AII). At this moment, the AII really is nothing but a collection of disparate services. Over the last few years the collection has grown so large, that it leaves the End-User in a rather desperate state. This paper provides an inventory of ...

We describe the development of a Spectral Energy Distribution (SED) matching technique using the current technology available through the Virtual Observatory. We outline the making of a detailed workflow technique that can take observational data of objects from various astronomical data archives and matches them to models generated through various model codes available. The result of running t...

In situ metrology overcomes many of the limitations of existing metrology techniques and is capable of exceeding the performance of present-day optics. A novel technique for precisely characterizing an X-ray bimorph mirror and deducing its two-dimensional (2D) slope error map is presented. This technique has also been used to perform fast optimization of a bimorph mirror using the derived 2D pi...

The Taiwanese-American Occultation Survey (TAOS) operates four telescopes to search for occultations of stars by Kuiper Belt Objects. This paper provides a detailed description of the TAOS multi-telescope system. Subject headings: Solar System, Astronomical Instrumentation, Astronomical Techniques

Explaining the origin of the orbit of 2000 CR105 (a ∼ 230 AU, q ∼ 45 AU) is a major test for our understanding of the primordial evolution of the outer Solar System. Gladman et al. (2001) showed that this objects could not have been a normal member of the scattered disk that had its perihelion distance increased by chaotic diffusion. In this paper we explore four seemingly promising mechanisms ...

Recent progress in the determinations of astronomical constants is reviewed. First is the latest estimation of the general relativistic scale constants, LC , LG, and LB (Irwin and Fukushima, 1999). By reestimating the uncertainty, the value of the rst constant is given as LC = 1:480 826 867 4 10 8 1:4 10 . Also noted is the rigorous relation among these three, LB = LC +LG LCLG. Based on the lat...

In this paper we present an automated method for classifying astronomical objects in multispectral wide-field images. The method is divided into three main tasks. The first one consists of locating and matching the objects in the multispectral images. In the second task we create a new representation for each astronomical object using its multispectral images, and also we find a set of features...

Astronomical data take on a multitude of forms – catalogs, data cubes, images, and simulations. The availability of software for rendering high-quality three-dimensional graphics lends itself to the paradigm of exploring the incredible parameter space afforded by the astronomical sciences. The software program Blender gives astronomers a useful tool for displaying data in a manner used by three...

The ADS Abstract and Article Services provide access to the astronomical literature through the World Wide Web (WWW). The forms based user interface provides access to sophisticated searching capabilities that allow our users to find references in the fields of Astronomy, Physics/Geophysics, and astronomical Instrumentation and Engineering. The returned information includes links to other on-li...
