MULTIPLE POPULATIONS IN THE OLD AND MASSIVE SMALL MAGELLANIC CLOUD GLOBULAR CLUSTER NGC 121 [PDF]
, 2016 We used a combination of optical and near-UV Hubble Space Telescope photometry and FLAMES/ESO-VLT high-resolution spectroscopy to characterize the stellar content of the old and massive globular cluster (GC) NGC 121 in the Small Magellanic Cloud (SMC ...

The Open Journal of AstrophysicsThe Magellanic Stream (MS) is known to contain multiple HI strands and corresponding stellar populations are being discovered. Combining a sample of 17 stars from the H3 (“Hectochelle in the Halo at High Resolution”) survey with 891 stars drawn from the

Estimating the dust production rate of carbon stars in the Small Magellanic Cloud [PDF]
, 2017 We employ newly computed grids of spectra reprocessed by dust for estimating the total dust production rate (DPR) of carbon stars in the Small Magellanic Cloud (SMC). For the first time, the grids of spectra are computed as a function of the main stellar

Interstellar Polarization in the Small Magellanic Cloud [PDF]
Symposium - International Astronomical Union, 1992 Data of our on-going program on the interstellar polarization in the Small Magellanic Cloud (SMC) seem to show a correlation between the UV extinction and the parameters of the Serkowski law which describe the polarization. Fits of popular interstellar dust models to the polarization data are not always satisfactory, being better for stars with small ...

THE PROPER MOTION OF THE MAGELLANIC CLOUDS. II. NEW RESULTS FOR FIVE SMALL MAGELLANIC CLOUD FIELDS
The Astronomical Journal, 2011 We present new results from a ground-based program to determine the proper motion of the Magellanic Clouds (MCs) relative to background quasars (QSOs), being carried out with the Ir?ne? du Pont 2.5?m telescope at Las Campanas Observatory, Chile. The data were secured over a time base of seven years and with eight epochs of observation As measured ...

Wolf-Rayet stars in the Small Magellanic Cloud as testbed for massive star evolution [PDF]
, 2017 The majority of Wolf-Rayet (WR) stars represent the stripped cores of evolved massive stars who lost most of their hydrogen envelope. In low metallicity environments, such as the Small Magellanic Cloud (SMC), stellar winds are weaker and binary ...

A New Look at the Kinematics of Neutral Hydrogen in the Small Magellanic Cloud [PDF]
, 2003 We have used the latest H I observations of the Small Magellanic Cloud (SMC), obtained with the Australia Telescope Compact Array and the Parkes telescope, to reexamine the kinematics of this dwarf irregular galaxy.

ALMA Observations of N83C in the Early Stage of Star Formation in the Small Magellanic Cloud [PDF]
, 2017 We have performed Atacama Large Millimeter/submillimeter Array (ALMA) observations in the 12CO( ), 13CO( ), C18O( ), 12CO( ), 13CO( ), and CS( ) lines toward the active star-forming region N83C in the Small Magellanic Cloud (SMC), whose metallicity is ...

Catalogue of Be/X-ray binary systems in the Small Magellanic Cloud: X-ray, optical and IR properties [PDF]
, 2015 This is a catalogue of 70 X-ray emitting binary systems in the Small Magellanic Cloud (SMC) that contain a Be star as the mass donor in the system and a clear X-ray pulse signature from a neutron star.

The Astrophysical Journal LettersWe present the three-dimensional kinematics of classical Cepheids (CCs) in the Small Magellanic Cloud (SMC) using Gaia DR3 data. By crossmatching the CCs obtained from the fourth phase of the Optical Gravitational Lensing Experiment with Gaia DR3, we ...
