Infrared extinction in the Small Magellanic Cloud [PDF]

Monthly Notices of the Royal Astronomical Society, 1984
On presente la photometrie JHK de membres des premiers types du PNM, brillants, rougis et non rougis, et on etudie la loi d'extinction dans ces bandes. La photometrie VRI de plusieurs membres des premiers types du PNM est egalement presentee et combinee aux observations existantes pour etudier l'extinction R et I.

XMM‐Newton Observations of the Peculiar Be X‐Ray Binary A0538‐66

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT A0538‐66 is a neutron star/Be x‐ray binary located in the Large Magellanic Cloud and, since its discovery in the 70s, it showed a peculiar behavior that makes it a unique object in the high‐mass x‐ray binaries scene: the extremely eccentric orbit (e=0.72$$ e=0.72 $$), the short spin period of the neutron star (P=69$$ P=69 $$ ms), the episodes ...

The Detection of Hot Molecular Cores in the Small Magellanic Cloud

The Astrophysical Journal Letters, 2023
We report the first detection of hot molecular cores in the Small Magellanic Cloud (SMC), a nearby dwarf galaxy with 0.2 solar metallicity. We observed two high-mass young stellar objects in the SMC with the Atacama Large Millimeter/submillimeter Array ...

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.

An ATCA Survey of H i Absorption in the Magellanic Clouds. I. H i Gas Temperature Measurements in the Small Magellanic Cloud [PDF]

Astrophysical Journal Supplement Series, 2019
We present the first results from the Small Magellanic Cloud portion of a new Australia Telescope Compact Array H i absorption survey of both of the Magellanic Clouds, comprising over 800 hr of observations.

Beyond Accretion Limits: The Rise of Pulsating Gems

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT The discovery of several ultraluminous X‐ray sources exhibiting fast and rapidly evolving X‐ray pulsations unequivocally associates these sources with accreting neutron stars orbiting relatively massive companion stars (> 8M ⊙$$ {}_{\odot } $$).

The VMC Survey. XXIX. Turbulence-controlled Hierarchical Star Formation in the Small Magellanic Cloud [PDF]

, 2018
In this paper we report a clustering analysis of upper main-sequence stars in the Small Magellanic Cloud, using data from the VMC survey (the VISTA near-infrared YJKs survey of the Magellanic system).

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).

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 ...
