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 Proper Motion of the Large Magellanic Cloud Using HST [PDF]

, 2005
We present a measurement of the systemic proper motion of the Large Magellanic Cloud (LMC) from astrometry with the High Resolution Camera (HRC) of the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope (HST). We observed LMC fields centered

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 ...

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

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 ...

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 ...

Astrophysical Distance Scale. VII. A Self-consistent, Multiwavelength Calibration of the Slopes and Relative Zero Points for the Run of Luminosity with the Color of Stars Defining the Tip of the Red Giant Branch

The Astronomical Journal, 2023
Given the recent successful launch of the James Webb Space Telescope, determining robust calibrations of the slopes and absolute magnitudes of the near- to mid-infrared tip of the red-giant branch (TRGB) will be essential to measuring precise ...

The H alpha Galaxy Survey VI. Star-forming companions of nearby field galaxies

, 2008
We present a search for star-forming satellite galaxies that are close enough to their parent galaxies to be considered analogues of the Magellanic Clouds. Our search technique relied on the detection of the satellites in continuum-subtracted narrow-band

RAM PRESSURE STRIPPING OF THE LARGE MAGELLANIC CLOUD’S DISK AS A PROBE OF THE MILKY WAY’S CIRCUMGALACTIC MEDIUM [PDF]

, 2015
Recent observations have constrained the orbit and structure of the Large Magellanic Cloud (LMC), implying a well-constrained pericentric passage about the Milky Way (MW) ∼50 Myr ago.
