Joint Analysis of near-infrared properties and surface brightness fluctuations of LMC star clusters

Understand

Surface brightness fluctuations have been proved to be a very powerful technique to determine the distance and characterize the stellar content in extragalactic systems.

• Nevertheless, before facing the problem of stellar content in distant galaxies, we need to calibrate the method onto nearby well-known systems.
• In this paper we analyze the properties at $J$ and $K_s$ bands of a sample of 19 star clusters in the Large Magellanic Cloud (LMC), for which accurate near-infrared (NIR) resolved star photometry, and integrated photometry are available.
• For the same sample, we derive the SBF measurements in $J$ and $K_s$-bands.
