Abstract:
We study the Large Magellanic Cloud Papillon Nebula (N 159-5), a
conspicuous High Excitation Blob (HEB) lying in the star forming
complex N 159. Using JHK near-infrared photometry obtained at the ESO
VLT with the ISAAC camera, we examine the stellar populations
associated with the Papillon, tracing their history using stellar
evolution models. Two populations are revealed: one composed of young,
massive stars with an age ∼3Myr, and a second consisting of older
lower mass stars of age spreading between 1 and 10Gyr. We analyze the
properties of those populations and discuss their significance in the
context of N 159. We also estimate that if the star at the center of
the Papillon is single its initial mass is ∼50 solar masses and it is
affected by an extinction Av∼7mag.
Description:
This table displays the results of a DAOPHOT/ALLSTAR photometry run on
VLT/ISAAC JHKs images from the LMC N159 (LHA 120-N 159) region.
ID refers to the chart in the paper. The "DAOPHOT errors" are the
internal photometry errors as reported by the DAOPHOT/ALLSTAR
algorithm.
