Magellanic Cloud Cepheids: Abundances [PDF]

The Astronomical Journal, 1998
We have determined parameters and abundances for three SMC and nine LMC Cepheids that have not been previously studied spectroscopically for metallicity, as well as three SMC and one LMC Cepheids observed previously by Luck & Lambert. This work nearly doubles the number of Cepheids with spectroscopic metallicities in the SMC and triples the number in ...

New 20-cm radio-continuum study of the small Magellanic cloud - part III: Compact Hii regions [PDF]

Serbian Astronomical Journal, 2012
We present and discuss a new catalogue of 48 compact Hii regions in the Small Magellanic Cloud (SMC) and a newly created deep 1420 MHz (λ=20 cm) radio-continuum image of the N19 region located in the southwestern part of the SMC.

COSMIC-L: A Photometric Catalog of Observed Stars in the Large Magellanic Cloud

The Astrophysical Journal Supplement Series
The Magellanic Clouds are two nearby dwarf irregular galaxies, the study of which can help us in understanding galaxy and stellar evolution. In particular, the Large Magellanic Cloud, the larger one, contains approximately 30 billion stars at various ...

Rotation of the Milky Way and the formation of the Magellanic Stream

, 2010
We studied the impact of the revisited values for the LSR circular velocity of the Milky Way (Reid et al. 2004) on the formation of the Magellanic Stream.

Limits on Planetary-mass Primordial Black Holes from the OGLE High-cadence Survey of the Magellanic Clouds

The Astrophysical Journal Letters
Observations of the Galactic bulge revealed an excess of short-timescale gravitational microlensing events that are generally attributed to a large population of free-floating or wide-orbit exoplanets.

Searching for Be star candidates within large databases

EPJ Web of Conferences, 2017
Long time surveys yield many light curves among their byproducts, useful to identify candidate Be stars that can be confirmed by spectroscopic follow-ups. We present in this work different techniques we have used to find Be star candidates in the Galaxy,

The Plane Quasar Survey: An Ionized Extension of the Magellanic Stream on the Northern Side of the Galactic Plane

The Astrophysical Journal Letters
The Magellanic Stream (MS) is a vast gaseous structure in the Milky Way halo, containing most of its mass in ionized form and tracing the interaction between the Large and Small Magellanic Clouds and the Galaxy. Using Hubble Space Telescope/Cosmic Origin

Orbits of LMC/SMC with recent ground-based proper motions

EPJ Web of Conferences, 2012
In recent years, with new ground-based and HST measurements of proper motions of the Magellanic Clouds being published, a need of a reanalysis of possible orbital history has arisen.

A Neutral Hydrogen Absorption Study of Cold Gas in the Outskirts of the Magellanic Clouds Using the GASKAP-H i Survey

The Astronomical Journal
Cold neutral hydrogen (H i ) is a crucial precursor for molecular gas formation and can be studied via H i absorption. This study investigates H i absorption in low column density regions of the Small and Large Magellanic Clouds (SMC and LMC) using the ...
