UVIT Study of the Magellanic Clouds (U-SMAC). III. Hierarchical Star Formation in the Small Magellanic Cloud Regulated by Turbulence

The Astrophysical Journal
The Small Magellanic Cloud (SMC), a satellite galaxy of the Milky Way, is an irregular dwarf galaxy exhibiting evidence of recent and ongoing star formation.

Optical spectroscopy of 20 Be/X-ray Binaries in the Small Magellanic Cloud

, 2009
We present a large sample (20 in total) of optical spectra of Small Magellanic Cloud (SMC) High-Mass X-ray Binaries obtained with the 2dF spectrograph at the Anglo-Australian Telescope.

Spectral Studies of Super‐Eddington Accreting Neutron Stars in the Magellanic Clouds

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT Major outbursts of BeXRBs offer a unique laboratory for studying accretion onto magnetized neutron stars (NSs) over a large dynamic range. The accreting material is entrained from the accretion disk by the strong magnetic field, and then channeled onto the NS, forming a so‐called accretion column (AC).

A new search for R Coronae Borealis stars in the SMC

EPJ Web of Conferences, 2017
R Coronae Borealis (RCB) stars are rare, and their evolutionary origin is not well understood. Since they are obscured due to formation of carbon dust around the star during their mass loss events, RCB stars can be classified as self-eclipsing variable ...

Massive Stars in the Tarantula Nebula: A Rosetta Stone for Extragalactic Supergiant HII Regions

Galaxies, 2019
A review of the properties of the Tarantula Nebula (30 Doradus) in the Large Magellanic Cloud is presented, primarily from the perspective of its massive star content.

The WFI Halpha spectroscopic survey of the Magellanic Clouds: Be stars in SMC open clusters [PDF]

, 2008
At low metallicity, B-type stars show lower loss of mass and, therefore, angular momentum so that it is expected that there are more Be stars in the Magellanic Clouds than in the Milky Way.

Principal sensory experiences of forest visitors in four countries, for evidence‐based nature therapy

People and Nature, Volume 6, Issue 6, Page 2480-2493, December 2024.
Abstract To advance the theoretical and practical underpinnings for nature therapies, i.e. nature exposure as a means to improve mental health, we compared the most memorable sensory experiences reported by forest tourists in Australia, Chile, China and Japan. Sensory experiences are a fundamental driver of the psychological effects of nature exposure.

The Metallicities of Five Small High-velocity Clouds

The Astrophysical Journal
High-velocity clouds (HVCs) are multiphase gas structures whose velocities (∣ v _LSR ∣ ≥ 100 km s ^−1 ) are too high to be explained by Galactic disk rotation.

The distance to the Small Magellanic Cloud from multiband period-luminosity relations for classical Cepheids and its dependence on metallicity

EPJ Web of Conferences, 2017
We present a distance determination to the Small Magellanic Cloud (SMC) using optical and near-infrared photometry from OGLE and IRSF. Applying a multiband method to V, I, J, H and K OGLE and IRSF data, we measured the SMC true distance modulus and mean ...

Multivariate comparisons of the period–light-curve shape distributions of Cepheids in five galaxies [PDF]

, 2007
A number of published tests suitable for the comparison of multivariate distributions are described. The results of a small power study, based on realistic Cepheid log period – Fourier coefficient data, are presented.
