Spectroscopic metallicities of Vega-like stars
(EDP Sciences, 2008-10)
Aims. We aim to determine the metallicities of 113 Southern Hemisphere Vega-like candidate stars in relation to the giant exoplanet host group and field stars. Methods. We applied two spectroscopic methods of abundance ...
Spectroscopic characterization and general features of piroxicam encapsulated in nanostructured lipid carriers
(Elsevier Science, 2021-05)
A detailed and unique spectroscopic study was developed to understand the interaction between an active principle and a lipid based-drug delivery system. Nanostructured lipid carrier (NLCs) loaded with piroxicam (PX) was ...
Integrated spectroscopic study of 7 star clusters in the Small Magellanic Cloud
(Wiley VCH Verlag, 2010-03-12)
We present flux-calibrated integrated spectra for 7 star clusters belonging to the Small Magellanic Cloud in the optical range (≈3600-7000 Å), obtained at CASLEO (Argentina). Three out of the 7 clusters were not previously ...
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 ...
Spectroscopic study of the extremely young O-type triple system Herschel 36 A in the Hourglass nebula - I. Orbital properties
(Wiley Blackwell Publishing, Inc, 2019-01-05)
We present a detailed spectroscopic study of Herschel 36 A (H36A), the main stellar component of the massive multiple system Herschel 36 in the Hourglass nebula, based on high-resolution optical spectra obtained along an ...
HII regions in the CALIFA survey: I. Catalog presentation
(Wiley Blackwell Publishing, Inc, 2020-03)
We present a new catalogue of H II regions based on the integral field spectroscopy (IFS) data of the extended CALIFA and PISCO samples. The selection of H II regions was based on two assumptions: a clumpy structure with ...
Intriguing detection of 12CO molecular emission in a classical Be star
(EDP Sciences, 2021-03)
Context. In the group of B stars with spectroscopic peculiarities, we can find the Be and the B[e] stars. The Be stars are early-type rapid rotators that present, as their principal characteristic, emission lines of hydrogen ...
Raman spectroscopic investigation of the effects of cosmetic formulations on the constituents and properties of human skin
(Mary Ann Liebert, 2012-02)
Objective: This study aimed to investigate the biochemical alterations in hydration and skin proteins, which are associated with the skin aging process, caused by cosmetic use. Background data: Many techniques have been ...
Celiac Disease: Historical Standpoint, New Perspectives of Treatments and Contemporary Research Techniques
(Bentham Science Publishers, 2018-05)
Celiac disease (CD) is an inflammatory syndrome that affects mainly the intestine, but also other organs. This ailment is also affected by the physicochemical behavior of gluten as such. From the medical standpoint, this ...
The KELT Follow-up Network and Transit False-positive Catalog: Pre-vetted False Positives for TESS
(IOP Publishing, 2018-11)
The Kilodegree Extremely Little Telescope (KELT) project has been conducting a photometric survey of transiting planets orbiting bright stars for over 10 years. The KELT images have a pixel scale of ∼23″ pixel-1 - very ...
