Stellar clusters multicolor photometry at OAUNI
(Universidad Nacional de Ingeniería, 2019-06-06)
In this work we present preliminary analysis of the astronomical photometry program for stellar clusters observed at OAUNI on the last years. Up to date twelve open clusters and nine globular clusters have been observed, ...
Optical multicolor polarization observations in the region of the open cluster NGC 5749
(EDP Sciences, 2007-12)
We present (UBVRI) multicolor linear polarimetric data for 31 of the brightest stars in the area of the open cluster NGC 5749 considered to study the properties of the interstellar medium (ISM) towards the cluster. Our ...
Multicolor Photometry of Red Giant Candidates in the Southern Open Cluster NGC 2447
(Inst Theoretical Physics Astronomy, 2005-12)
Photoelectric photometry in the UBV, DDO and Washington systems is
presented for 14 late-type giant candidates of the southern open cluster
NGC 2447. By applying two independent photometric criteria, nine stars
are found ...
Multicolor UBVRI polarimetry of NGC 4755 and the beta Cephei population
(Universidad Nacional Autónoma de México. Instituto de Astronomía, 2015-04)
Se presentan observaciones polarimétricas en las bandas U BV RI de 66 estrellas situadas en la dirección del cúmulo NGC 4755, incluyendo once β Cephei. Casi la mitad de estas variables muestran indicios de polarización ...
XMMU J100750.5+125818: a strong lensing cluster at z = 1.082
(2010)
We report on the discovery of the X-ray luminous cluster XMMU J100750.5+125818 at redshift 1.082 based on 19 spectroscopic members. The cluster displays several strong lensing features. SED modeling of the lensed arc features ...
Photometric observations and Coravel radial velocities of red giant candidates in open clusters
(Asociación Argentina de Astronomía, 2008-12)
Presentamos fotometrıa fotoelectrica multicolor de alta precision y velocidades radiales (VRs) Coravel para una muestra de candidatas a gigantes rojas (GRs) en nueve cumulos abiertos galacticos. Encontramos que aproximadamente ...
