Exploring Magellanic Interactions Through Bridge and Small Magellanic Cloud Dynamics

, 2019
In recent years, our view of the Magellanic Clouds has shifted due to a rapidly expanding pool of data. Hubble Space Telescope-measured proper motions (PMs) of the Clouds revealed their first infall and the timescale on which they most recently interacted.

Dual Directional Expansion of Classical Cepheids in the Small Magellanic Cloud Revealed by Gaia Data Release 3

The Astrophysical Journal Letters
We 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 ...

Astronomy & Astrophysics
Context. The Magellanic Clouds (MCs) offer a unique laboratory for studying galaxy interaction and the evolution of dwarf galaxies. The star formation history (SFH), which traces when and how stars formed, provides powerful constraints for the dynamical ...

ABOUT CHEMICAL COMPOSITION OF SUPERGIANT PMMR145 IN SMALL MAGELLANIC CLOUD. OSMIUM.

Odessa Astronomical Publications, 2012
The abundance analysis of six Ksupergiants of the Small Magellanic Cloud (Hill 1997) showed that the heavier elements (La, Ce, Nd, Eu) have the excess relative to iron [El/Fe]=+0.4 dex, on average, for the sample of five stars (PMMR23, PMMR27, PMMR48 ...

Response of the LMC’s Bar to a Recent SMC Collision and Implications for the SMC’s Dark Matter Profile

The Astrophysical Journal
The LMC’s stellar bar is offset from the outer disk center, tilted from the disk plane, and does not drive gas inflows. These properties are atypical of bars in gas-rich galaxies, yet the LMC bar’s strength and radius are similar to typical barred ...

Small Magellanic Cloud Cepheids Observed with the Hubble Space Telescope Provide a New Anchor for the SH0ES Distance Ladder

The Astrophysical Journal
We present phase-corrected photometric measurements of 88 Cepheid variables in the core of the Small Magellanic Cloud (SMC), the first sample obtained with the Hubble Space Telescope's (HST) Wide Field Camera 3, in the same homogeneous photometric system

The structure of the Small Magellanic Cloud

The Astrophysical Journal, 1986
Dans l'espace des vitesses, il semble y avoir deux entites separees dans la distribution HI du PNM, chacune ayant sa population stellaire et sa population nebulaire propres. Pour delimiter ces regions, on a effectue une photometrie B.V.

Wolf-Rayet stars in the Magellanic Clouds. V - Binaries in the Small Magellanic Cloud

The Astrophysical Journal, 1988
Repeated spectroscopic observations of all eight W-R stars in the SMC are reported. Two of the stars are of the late, cool WN subclass, with one possibly an extreme Of star. One is definitely, the other probably, constant in radial velocity. Five early, hot WN (WNE) stars all exhibit O-type spectral lines.
