Star formation in the Large Magellanic Cloud. II. Evidence for an old intermediate-age burst of stellar activity?

VALLENARI A., CHIOSI C., BERTELLI G. and ORTOLANI S.

Abstract (from CDS):

In this paper, we present the BV-CCD photometry of three stellar fields in the Large Magellanic Cloud (LMC). The colour-magnitude diagrams (CMD) and the luminosity functions (LF) are studied with the aim of reconstructing the past history of star formation. These fields are located outside the main body of the LMC. The existence of an enhancement in the star formation at ages as old as 6-8Gyr is suggested by the observational data in the regions East of the Bar. In contrast, West of the center, in the direction of the SMC, the bulk of star formation appears to have occurred as recently as 2-3Gyr ago. The past history of the star formation is discussed with particular attention to the possible dynamical interaction between the three galaxies LMC, SMC and Milky Way.
