The metallicity distribution of bulge clump giants in Baade's Window
Galaxy: bulge – Galaxy: formation – Galaxy: abundances – Stars: abundances – Stars: atmosphere
2011/10/20
We seek to constrain the formation of the Galactic bulge by means of analysing the detailed chemical composition of a large sample of red clump stars in Baade's window. We measure [Fe/H] in a sample o...
Searching for Saturn's Dust Swarm: Limits on the size distribution of Irregular Satellites from km to micron sizes
Solar System: satellites
2011/10/8
We describe a search for dust created in collisions between the Saturnian irregular satellites using archival \emph{Spitzer} MIPS observations. Although we detected a degree scale Saturn-centric exces...

CONSTRAINED DECONVOLUTION BY EXPLICIT CORRECTION OF FOURIER COMPONENTS OF THE UNKNOWN DISTRIBUTION
UNKNOWN DISTRIBUTION deconvolution
2009/3/19
The physical constraints were applied in the problem of deconvolution
by explicitly correcting noise affected Fourier components of the unknown
distribution. The method gives the constrained estimat...
A COMPARSION OF TWO SPHERICAL MASS DISTRIBUTION MODELS
MASS DISTRIBUTION MODELS Two spherically symmetric generalised isochrone model
2009/3/13
Two spherically symmetric mass-distribution models - a special
case of the generalised Schuster density law and the generalised isochrone model
(both yield the same approximate density dependence on...
