Infrared composition of the Large Magellanic Cloud

TL;DR

This study uses AKARI infrared data to analyze the Large Magellanic Cloud, classifying stars and assessing their contribution to the galaxy's infrared emission, shedding light on galaxy evolution and star formation.

Contribution

It provides a multiwavelength catalog of the LMC with star classification and flux contribution analysis based on mid- and near-infrared data, a novel comprehensive dataset.

Findings

Different classes of stars are separated in color-color and color-magnitude diagrams.

The contribution of various star types to the total infrared flux of the LMC is quantified.

The study enhances understanding of the role of small irregular galaxies in cosmic star formation.

Abstract

The evolution of galaxies and the history of star formation in the Universe are among the most important topics in today's astrophysics. Especially, the role of small, irregular galaxies in the star-formation history of the Universe is not yet clear. Using the data from the AKARI IRC survey of the Large Magellanic Cloud at 3.2, 7, 11, 15, and 24 {\mu}m wavelengths, i.e., at the mid- and near-infrared, we have constructed a multiwavelength catalog containing data from a cross-correlation with a number of other databases at different wavelengths. We present the separation of different classes of stars in the LMC in color-color, and color-magnitude, diagrams, and analyze their contribution to the total LMC flux, related to point sources at different infrared wavelengths.
