Basic parameters of three star clusters in the Small Magellanic Cloud: Kron 11, Kron 63 and NGC 121 (BLACKWELL, 2008-11-11)We present observations for three star clusters, Kron 11, Kron 63 and NGC 121, in the Small Magellanic Cloud. We have studied their structure and derived their fundamental parameters by means of their luminosity functions, ...

(2010)We present optical and infrared photometry for VdB-Hagen 67, an overlooked old open cluster located at l = 273.◦76, b = −0.◦375 (RA 09h26m45s, Dec.−51◦16 00 , J2000.0) in the fourth Galactic quadrant, in the direction ...

(1996-12)We present RI and JHK photometry for 888 and 204 carbon (C) stars, respectively, of the 1035 C stars found by Blanco and his collaborators in 52 fields of the Large Magellanic Cloud (LMC). The results of our analysis of ...

(1999-10-02)Optical positions relative to the Hipparcos Catalogue (ESA 1997) have been obtained for the optical counterparts of 15 faint (B 20 − 23) southern compact extragalactic radio sources (CERS). Most of these sources are ...
-
(2001)Optical positions relative to the Hipparcos Catalogue (ESA 1997) have been obtained for the optical counterparts of 28 faint (B 20−23) southern compact extragalactic radio sources (CERS). Most of these sources are not ...
-
(2002)Optical positions relative to the Hipparcos Catalogue (ESA 1997) have been obtained for the optical counterparts of 38 faint (B 20−24) southern compact extragalactic radio sources (CERS). Many of these sources are not ...
-
(IOP PUBLISHING, 2008-09)We present stellar metallicities derived from Ca II triplet spectroscopy in over 350 red giant branch stars in 13 fields distributed in different positions in the Small Magellanic Cloud, ranging from similar to 1 degrees ...
-
(2007)The colour–magnitude diagram (CMD) of the intermediate-age Large Magellanic Cloud star cluster NGC 2154 and its adjacent field has been analysed using Padova stellar models to determine the cluster’s fundamental parameters ...
-
(2001)Proper motions, positions, nding charts and magnitudes are given for 147 newly discovered stars with proper motions larger than 0.15 arcsec/year. They were found in a search for high proper motion stars carried out in ...
-
(Elsevier, 2010)We present homogeneous V, I CCD photometry of nine stellar fields in the two inner quadrants of the Galactic plane. The lines-of-view to most of these fields aim in the direction of the very inner Galaxy, where the ...
-
(EDP Sciences, 2015)Context. The spiral structure of the Milky Way (MW) is highly uncertain and is the subject of much discussion nowadays. Even the spiral structure close to the Sun and the real nature of the so-called Local or Orion arm are ...
-
(ESO, 2010)Context. Open clusters are excellent tracers of the structure, kinematics, and chemical evolution of the disk and a wealth of information can be derived from the spectra of their constituent stars. Aims. We investigate ...
-
(1999)Proper motions, positions, nding charts and magnitudes are given for 293 newly discovered stars with proper motions larger than 0.15 arcsec/year. They are located between −5 and −30 in declination, and 13h 30m and ...
-
(Oxford University Press on behalf of the Royal Astronomical Society, 2013)If stars form in clusters but most stars belong to the field, understanding the details of the transition from the former to the latter is imperative to explain the observational properties of the field. Aging open ...
-
(Oxford University Press on behalf of the Royal Astronomical Society, 2013)The discovery and subsequent detailed study of T dwarfs have provided many surprises and pushed the physics and modelling of cool atmospheres in unpredicted directions. Distance is a critical parameter for studies of ...
-
(2007)We present ground-based B-and R-band color-magnitude diagrams (CMDs) reaching the oldest main-sequence (MS) turnoffs with good photometric accuracy for 12 fields in the Small Magellanic Cloud (SMC). Our fields, located ...
-
(1997-05-01)Optical positions relative to the International Reference Stars Catalogue (IRS), and therefore in the system of the FK5, have been obtained for the optical counterparts of 40 compact extragalactic radio sources south of ...
-
(1998-08)Optical positions relative to the Hipparcos Catalogue, and therefore within the International Celestial Reference System (ICRS), have been obtained for the optical counterparts of 25 compact extragalactic radio sources ...
-
(2003)Photometric distances derived from VRI photometry are given for 44 high proper motion stars from the Cerro El Roble proper motion surveys of Wroblewski & Torres and Wroblewski & Costa. The observations were carried out ...
