Dust in the Large Magellanic Cloud [PDF]

Symposium - International Astronomical Union, 1973
A brief review of extinction effects is followed by a discussion of new Cerro Tololo Schmidt plates. They were exposed on parts of the LMC with filters which reveal the presence or absence of a continuum, such as one scattered on dust, in H ii regions. The results are presented in comparison with the Orion nebula which was observed in the same way. The

The Molecular Cloud Population of the Large Magellanic Cloud [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractWe have mapped an extensive sample of molecular clouds in the Large Magellanic Cloud (LMC) at 11 pc resolution in the CO(1-0) line as part of the Magellanic Mopra Assessment (MAGMA). We identify clouds as regions of connected CO emission and determine their sizes, line widths, and fluxes.

Chemical Evolution of the Universe and its Consequences for Gravitational‐Wave Astrophysics

Annalen der Physik, Volume 536, Issue 2, February 2024.
Population properties of double compact object mergers (especially binary black holes) are sensitive to the metallicity dependent cosmic star formation history. The uncertainty of this quantity cannot be ignored and makes the interpretation of current gravitational wave observations difficult.

Five Massive Contact Binaries with Twin Components in LMC

The Astrophysical Journal, 2023
Massive contact binaries refer to the close binary systems in which the components have filled their respective Roche lobes and share a common envelope with early-type spectra.

Threading the Magellanic Needle: Hypervelocity Stars Trace the Past Location of the LMC

The Astrophysical Journal Letters
Recent discoveries have shown that a population of hypervelocity stars (HVSs) originates from the Large Magellanic Cloud (LMC). We use three such HVSs as dynamical tracers to constrain the past orbit of the LMC.

Magellanic Clouds elemental abundances from F supergiants: Revisited results for the Large Magellanic Cloud [PDF]

Astronomy & Astrophysics, 2001
With an improved method of the LTE abundance analysis for most elements (Kovtyukh & Andrievsky 1999), the abundances have been re-investigated in nine F supergiants of the Large Magellanic Cloud. The NLTE calculations for carbon, oxygen and sodium, based on Kurucz's atmospheric models with an over-all metal deficiency, were carried out.

The Period–Luminosity Relation of Long-period Variables in the Large Magellanic Cloud Observed with ATLAS

The Astrophysical Journal Supplement Series
Period–luminosity (PL) relations of long-period variables (LPVs) are a powerful tool to map the distances of stars in our Galaxy, and are typically calibrated using stars in the Large Magellanic Cloud (LMC).

The Large Magellanic Cloud PN population [PDF]

Proceedings of the International Astronomical Union, 2015
AbstractThe Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) allow us to study late stellar evolution in environments that are respectively about a half and a quarter the metallicity of the Milky Way. With a known distance and low reddening, the LMC is an excellent environment to study PNe and conduct multiple studies. Over the past twelve

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 ...

Scylla. V. Constraints on the Spatial and Temporal Distribution of Bursts and the Interaction History of the Magellanic Clouds from Their Resolved Stellar Populations

The Astrophysical Journal
We measure the star formation histories (SFHs) from the Scylla survey in ∼98,000 pc ^2 and ∼75,000 pc ^2 of the Small Magellanic Cloud (SMC) and Large Magellanic Cloud (LMC), respectively, using deep Hubble Space Telescope imaging (80% complete to > 1 ...
