This paper deals about astronomical orientation of Incas objects in Ollantaytambo, which is located about 35 km southeast from Machu Picchu, about 40 km northwest from Cusco, and lies in the Urubamba ...
A new Monte Carlo method has been developed in order to derive ages of young embedded clusters within massive star forming regions where there is strong differential reddening. After foreground and in...
A basic property of objects, like galaxies and halos that form in cosmological structure formation simulations, is their shape. Here, we critically investigate shape determination methods that are com...
Determining the Parameters of Massive Protostellar Clouds via Radiative Transfer Modeling
Parameters of Massive Protostellar Clouds Radiative Transfer Modeling
2010/11/16
A one-dimensional method for reconstructing the structure of prestellar and proto-stellar clouds is presented. The method is based on radiative transfer computations and a comparison of theoretical an...
Determining the forsterite abundance of the dust around AGB stars
forsterite abundance of the dust AGB stars
2010/11/11
We present a diagnostic tool to determine the forsterite abundance of the dust ejected by AGB stars. Our method is based on a comparison between the observed strength of spectral bands of forsterite a...
A New Method for Determining Geometry of Planetary Images
Instrumentation and Methods for Astrophysics (astro-ph.IM)

This paper presents a novel semi-automatic image processing technique to estimate accurately, and objectively, the disc parameters of a planetary body on an astronomical image.
Determining Absorption, Emissivity Reduction, and Local Suppression Coefficients inside Sunspots
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
The power of solar acoustic waves is reduced inside sunspots mainly due to absorption, emissivity reduction, and local suppression. The coefficients of these power-reduction mechanisms can be determin...
