Four new planetary nebulae towards the Small Magellanic Cloud [PDF]

Monthly Notices of the Royal Astronomical Society, 2015
We present four new planetary nebulae (PNe) discovered in the Small Magellanic Cloud (SMC) from deep UK Schmidt telescope (UKST) narrow band H-alpha and broad-band short-red "SR" continuum images and confirmed spectroscopically. All new PNe show strong [NII]/H-alpha ratios in their spectra.

Resolved Kinematics of Runaway and Field OB Stars in the Small Magellanic Cloud [PDF]

Astrophysical Journal, 2018
We use Gaia Data Release 2 proper motions of field OB stars from the Runaways and Isolated O-Type Star Spectroscopic Survey of the Small Magellanic Cloud (SMC) to study the kinematics of runaway stars.

Hα imaging for BeXRBs in the Small Magellanic Cloud [PDF]

Proceedings of the International Astronomical Union, 2016
AbstractThe Small Magellanic Cloud (SMC) hosts a large number of high-mass X-ray binaries, and in particular of Be/X-ray Binaries (BeXRBs; neutron stars orbiting OBe-type stars), offering a unique laboratory to address the effect of metalicity. One key property of their optical companion is Hα in emission, which makes them bright sources when observed ...

Optical Spectra of Radio Planetary Nebulae in the Small Magellanic Cloud [PDF]

Serbian Astronomical Journal, 2008
We present preliminary results from spectral observations of four (4) candidate radio sources co-identified with known planetary nebulae (PNe) in the Small Magellanic Cloud (SMC).

Properties of Anomalous and Type II Cepheids in the Small and Large Magellanic Clouds

EPJ Web of Conferences, 2017
The Small Magellanic Cloud (SMC) and Large Magellanic Cloud (LMC) give us the possibility to study individual variable star types in a new way. Literature data provide us with photometric information about objects from the ultraviolet to the infrared ...

Modeling CO, CO$_2$ and H$_2$O ice abundances in the envelopes of young stellar objects in the Magellanic Clouds

, 2018
Massive young stellar objects in the Magellanic Clouds show infrared absorption features corresponding to significant abundances of CO, CO$_2$ and H$_2$O ice along the line of sight, with the relative abundances of these ices differing between the ...

The period distribution of Cepheids: a test of stellar evolution

EPJ Web of Conferences, 2015
The period distributions of classical Cepheids in the Small and Large Magellanic Cloud are quite different. Using the TRILEGAL population synthesis code and a theoretical instability strip the ultimate aim is to understand these differences ...

Testing the effects of opacity and the chemical mixture on the excitation of pulsations in B stars of the Magellanic Clouds [PDF]

, 2012
The B-type pulsators known as \beta Cephei and Slowly Pulsating B (SPB) stars present pulsations driven by the \kappa mechanism, which operates thanks to an opacity bump due to the iron group elements.

Helium Variation in Four Small Magellanic Cloud Globular Clusters

Astrophysical Journal, 2019
The multiple stellar populations (MPs) of the ∼11–13 Gyr old globular clusters (GCs) in our Galaxy are characterized by the different content of several light elements.

INTEGRAL observations of the Small Magellanic Cloud

, 2007
The first INTEGRAL observations of the Small Magellanic Cloud (carried out in 2003) are reported in which two sources are clearly detected. The first source, SMC X-1, shows a hard X-ray eclipse and measurements of its pulse period indicate a continuation
