HST/ACS observations of NGC 346
We present a photometric study of the star-forming region NGC 346 and its surrounding field in the Small Magellanic Cloud, using data taken with the Advanced Camera for Surveys... -
BVRI observations of LMC Cepheids
A homogeneous set of ground-based BVRI observations of ~600 Cepheids is presented to check the Cepheid period-luminosity (PL) zero point for the Large Magellanic Cloud (LMC).... -
Photometry of Cepheids in Magellanic Clouds
We report BV(RI)C data for a select group of 14 Cepheids in the Large Magellanic Cloud and eight in the Small Magellanic Cloud that have preexisting radial velocity curves. The... -
SMC and Bridge extended catalog
A survey of extended objects in the Magellanic System was carried out on the ESO/SERC R and J Sky Survey Atlases. The present work is dedicated to the Small Magellanic Cloud and... -
AO-assisted BVRI+Ha imaging of NGC330 with SAMI
H{alpha} emission is a clear indicator of circumstellar activity in Be stars, historically employed to assess the classical Be star (CBe) population in young open clusters... -
UV-to-NIR spectra of 8 Wolf-Rayet stars in LMC
Are WO-type Wolf-Rayet (WR) stars in the final stage of massive star evolution before core-collapse? Although WC- and WO-type WRs have very similar spectra, WOs show a much... -
NIR light curves of type II Cepheids
We present time-series photometry of 21 nearby type II Cepheids in the near-infrared J, H, and Ks passbands. We use this photometry, together with the Third Gaia Early Data... -
Red supergiants in 12 Local Group galaxies
This work establishes the most complete sample of red supergiants (RSGs) in 12 low-mass galaxies (WLM, IC 10, NGC 147, NGC 185, IC 1613, Leo A, Sextans B, Sextans A, NGC 6822,... -
2MASS red supergiants in the SMC
Despite the many successes that modern massive star evolutionary theory has enjoyed, reproducing the apparent trend in the relative number of red supergiants (RSGs) and... -
WISE & Spitzer obs. of OGLE Miras in the LMC
We present the mid-infrared (mid-IR) period-luminosity relations (PLRs) using over 1000 Mira variables in the Large Magellanic Cloud, for the four Wide-field Infrared Survey... -
Phot. measurements of stars in & near 1E 0102.2-7219
1E 0102.2-7219 (hereafter E0102) is a young supernova remnant (SNR) in the Small Magellanic Cloud. It contains oxygen-rich SN ejecta, a possible neutron star (NS), and a small... -
Compilation of Cepheids in the MW and MCs
The Cepheid period-luminosity (PL) relation is the key tool for measuring astronomical distances and for establishing the extragalactic distance scale. In particular, the local... -
METAL Hubble prog. II. LMC dust-to-gas ratio
A key component of the baryon cycle in galaxies is the depletion of metals from the gas to the dust phase in the neutral interstellar medium (ISM). The METAL (Metal Evolution,... -
Radial velocity for 10 giant eclipsing binaries
We present a new study of late-type eclipsing binary stars in the Small Magellanic Cloud (SMC) undertaken with the aim of improving the distance determination to this important... -
Kinematic & fundamental parameters; OB stars
Runaway OB stars are ejected from their parent clusters via two mechanisms, both involving multiple stars: the dynamical ejection scenario (DES) and the binary supernova... -
RSGs in the LMC & sp. follow-up for LMC & SMC
The binary fraction of unevolved massive stars is thought to be 70%-100% but there are few observational constraints on the binary fraction of the evolved version of a subset of... -
CII emission-line stars in LMC with MagE spectra
We present a narrowband imaging survey of the Large Magellanic Cloud (LMC), designed to isolate the CII{lambda}{lambda}7231,7236 emission lines in objects as faint as... -
Spectra of a rare low-mass Wolf-Rayet star in LMC
We report the serendipitous discovery of an object, UVQSJ060819.93-715737.4, with a spectrum dominated by extremely intense, narrow CII emission lines. The spectrum is similar... -
OB stars embedded in the HI gas of SMC
We investigate the kinematics of neutral gas in the Small Magellanic Cloud (SMC) and test the hypothesis that it is rotating in a disk. To trace the 3D motions of the neutral... -
Deep Chandra survey of the SMC. III. HMXBs
We have compiled the most complete census of high-mass X-ray binaries (HMXBs) in the Small Magellanic Cloud with the aim to investigate the formation efficiency of young...
