Extinction Map of Baade's Window
Recently Wo zniak & Stanek (1996) proposed a new method to investigate interstellar extinction, based on two band photometry, which uses red clump stars as a means to construct the reddening curve. I apply this method to the color-magnitude diagrams obtained by the Optical Gravitational Lensing Experiment (OGLE) to construct an extinction map of (40 0) 2 region of Baade's Window, with resolutio...
متن کاملOn the extinction towards Baade’s Window
An analysis is made on the morphology of the sequences, formed by stars distributed along the line of sight in (V,V–I) CMDs (Colour Magnitude Diagram) from Baade’s Window (l=1. ◦0, b=−3. ◦9). The extinction is due to an absorbing layer with an effective thickness of about 100 pc. A linearly, with distance, increasing extinction up to a maximum value inside the absorbing layer is in first order ...
متن کاملNorm Dependence of the Coefficient Map on the Window Size1
For sparse exponent sequences (k) 1 ?1 , satisfying a suitablèseparation condition' deened by an auxiliary sequence , one has a `coeecient map' C giving (c k) 1 ?1 =: c from observation of f = P 1 k=?1 c k e ii k t on any arbitrarily small interval ?; ]. In terms of , we estimate the norm of C : L 2 ?; ] ! ` 2 , asymptotically as ! 0. In particular, for (k) 1 ?1 k p (p > 1) we get a bound which...
متن کاملA Galactic Plane Relative Extinction Map from 2MASS
We present three 14400 square degree relative extinction maps of the Galactic Plane (|b|< 20◦) obtained from 2MASS using accumulative star counts (Wolf diagrams). This method is independent of the colour of the stars and the variation of extinction with wavelength. Stars were counted in 3′ .5× 3′ .5 boxes, every 20′′. 1◦×1◦ surrounding fields were chosen for reference, hence the maps represent ...
متن کاملExtinction and chaotic patterns in map lattices under hostile conditions.
Population dynamics in spatially extended systems can be modeled by Coupled Map Lattices (CML). We employ such equations to study the behavior of populations confined to a finite patch surrounded by a completely hostile environment. By means of the Galerkin projection and the normal solution ansatz, we are able to find analytical expressions for the critical patch size and show the existence of...
