Spectroscopic and spectropolarimetric observations with high spectral resolution provide extremely rich information on the physical conditions of distant...
Signature of main sequence internal structure in post-main sequence stars
Post Main Sequence (post MS) stars keep a trace of their past main sequence history. Typically, the presence or not of an Intermediate Convective Zone (ICZ)...
Signature of the solar cycle in the low degree p-modes using Mark-I
High quality observations of the low degree p-modes exist for almost two complete solar cycles using the solar spectrophotometer Mark-I, located and operating...
Signatures of Granulation in the Spectra of K-Dwarfs
Very high resolution (R>150,000) spectra of a small sample of nearby K-dwarfs have been acquired to measure the line asymmetries and central wavelength shifts...
Silicates versus Sulphur - Searching for Clues about Ionian Vulcanism with Canaricam
Vulcanism was first detected on Io in 1978 by Voyager 1. Since then it has been recognised that Io is the most volcanically active body in the Solar System...
Simmulating Interferograms for Testing Big Dimentions Optics
We based on two interferometric modern techniques: Electronic Speckle Pattern Interferometry and Fringe Projection Technique we had realized simulations of...
Simulated UVEX colors with reddening (Groot+, 2009)
To interpret the UVEX observations, simulations of the colours of stars and the effect of reddening are a very powerful and important tool. In obtaining the...
Simulating Galaxy Cluster Assembly: Do Clusters form from Groups?
We investigate the assembly histories 56 of galaxy clusters using a pair of cosmological LCDM N-body simulations. We track infalling galaxy subhalos with masses...
