Spectroscopic study and thermal behavior of trivalent lanthanides and yttrium(III) chelates of EDTA using TG-DSC, FTIR, and TG-DSC coupled to FTIR
(2013-07-23)
Solid-state compounds of yttrium and lanthanide chelates of ethylenediaminetetraacetic acid have been synthesized. Simultaneous thermogravimetry and differential scanning calorimetry (TG-DSC), theoretical and experimental ...
The nature of the NGC 2546: Not one but two open clusters
(EDP Sciences, 2020-01)
Context. As part of a broader project on the role of binary stars in clusters, we present a spectroscopic study of the open cluster NGC 2546, which is a large cluster lacking previous spectroscopic analysis. Aims: We report ...
Structured light illumination for order sorting in Echelle spectrometers
(Optical Society of America, 2017-11)
We report on the operation of an echelle spectrometer under structured light illumination. Each diffraction order of the spectrometer is encoded with a certain periodic structure allowing for order sorting by numerical ...
The Gaia-ESO Survey: detection and characterisation of single-line spectroscopic binaries
(European Southern Observatory, 2020)
Context. Multiple stellar systems play a fundamental role in the formation and evolution of stellar populations in galaxies. Recent and ongoing large ground-based multi-object spectroscopic surveys significantly increase ...
Thermoanalytical, spectroscopic and DFT studies of heavy trivalent lanthanides and yttrium(III) with Oxamate as Ligand
(2017-07-01)
Solid-state LnL3·nH2O complexes, where Ln stands for trivalent lanthanides (Tb to Lu) or yttrium(III) and L is oxamate (NH2COCO2-), have been synthesized. The characterization of the complexes was performed by using elemental ...
Normal A0−A1 stars with low rotational velocities: I. Abundance determination and classification
(EDP Sciences, 2014-02)
Context: The study of rotational velocity distributions for normal stars requires an accurate spectral characterization of the objects in order to avoid polluting the results with undetected binary or peculiar stars. This ...
