Atomic Diffusion and Mixing in Old Stars I. VLT/FLAMES-UVES Observations of Stars in NGC 6397
A. J. Korn, F. Grundahl, O. Richard +5
We present a homogeneous photometric and spectroscopic analysis of 18 stars along the evolutionary sequence of the metal-poor globular cluster NGC 6397 ([Fe/H] = -2), from the main…
The use of the Cherenkov radiation and the fluorescence light to calibrate the energy of giant air showers
L. G. Dedenko, D. A. Podgrudkov, T. M. Roganova +3
In terms of the quark-gluon string model the analysis of the classic procedure to estimate the energy of giant air showers with help of the parameter s(600) (a density of energy de…
On the contribution of point sources to the Galactic ridge X-ray emission
M. Revnivtsev, S. Sazonov
We analyzed deep Chandra observations of the Galactic plane region centered at l=28.55, b=-0.03 with the aim to obtain the best possible constraints on the contribution of weak poi…
X-ray emission from the stellar population in M32
M. Revnivtsev, E. Churazov, S. Sazonov +2
Using Chandra observations, we study the X-ray emission of the stellar population in the compact dwarf elliptical galaxy M32. The proximity of M32 allows one to resolve all bright…
