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...

Celeste is a procedure for inferring astronomical catalogs that attains state-of-the-art scientific results. To date, Celeste has been scaled to at most hundreds of megabytes of astronomical images: Bayesian posterior inference is notoriously demanding computationally. In this paper, we report on a scalable, parallel version of Celeste, suitable for learning catalogs from modern large-scale ast...

The detection of faint astronomical signals is limited by natural environmental factors and by artificially generated nuisances, such as radio interference and light pollution. The interference can be mitigated by choosing to locate observatories at places where the natural interference is minimised, and by controlling the nuisance emissions. This article describes the range of the nuisances fo...
