A sample of 33 eclipsing binaries observed in a field of the SMC with FLAMES@VLT is presented. The radial velocity curves obtained, together with existing OGLE light curves, allowed the determination of all stellar and orbital parameters of these bin

Aim: Our purpose is to provide reliable stellar parameters for a significant sample of eclipsing binaries, which are representative of a whole dwarf and metal-poor galaxy. We also aim at providing a new estimate of the mean distance to the SMC and of

Evolved low-mass stars of a wide range of metallicity bear signatures of a non-standard mixing event in their surface abundances of Li, C, and N, and in their 12C/13C ratio. A Na overabundance has also been reported in some giants of open clusters bu

The two-dimensional imaging properties of scanning harmonic microscopes are considered. The two-dimensional weak-object transfer functions for non-confocal (point source and large-area incoherent detector) and confocal (point source and point detecto

The signal level in a fibre-optical confocal scanning microscope using step-index profile fibres is investigated. The dependence of the signal level on the fibre parameter V is studied. Two different systems are investigated. For the first case of a

A series of new, relatively high molecular weight poly(arylene ether azomethine)s was prepared by condensation of silylated bisphenols with bis[N-(4-fluorobenzylideneaniline)]s (BFBAs) in polar apr...

The carbon isotopic ratio,12C/13C, is a tracer of the mixing events during the evolution along the giant branch, due to the conversion of12C into13C (and14N) via the CN cycle. A decrease of this ratio from 90, the solar value, to 20–25, is expected

It is known that signal level in single-, two- and three-photon confocal fluorescence microscopy increases with the size of the detector. Here we evaluate the signal-to-noise and the signal-to-background criteria for these microscopes. We investigate
