Abundance Patterns in S-type AGB stars : Setting Constraints on Nucleosynthesis and Stellar Evolution Models
Abundance Patterns Setting Constraints Stellar Evolution Models
2010/11/12
During the evolution on the AGB, S-type stars are the first objects to experience s-process nucleosynthesis and third dredge-ups, and therefore to exhibit sprocess signatures in their atmospheres.
Quasi-Stationary and Transient Patterns in Jets

2010/11/10
Apparent evolution of relativistic flows as traced by radio emission results from a ombination of several factors related to propagation of relativistic blobs or shocks, velocity,density and pressure ...
We study the expected variability patterns of blazars within the two-zone acceleration model putting special emphasis on flare shapes and spectral lags. We solve semi-analytically the kinetic equation...
A POSSIBLE THEORETICAL EXPLANATION OF CCD INTERFERENCE PATTERNS
CCD INTERFERENCE PATTERNS solar spectrophotometry
2009/4/8
Quite high interference disturbance has been noticed in our SBIG
ST-6 CCD camera when applied in solar spectrophotometry. This behaviour has
been explained quantitatively by the effect of spatial in...
