Thursday

We will present early results of the young and massive star cluster R136 in the centre of the Tarantula Nebula in the Large Magellanic Cloud. To analyse the dense stellar content of R136 we require high spatial spectroscopy and photometry of the core within a radius of 0.5 parsec. The analysis is based on spectroscopic UV, optical and Halpha HST/STIS data (Crowhter et al. 2016) and photometric optical HST/WFPC3 (de Marchi et al. 2011) and near-IR VLT/SPHERE (Khorrami et al. 2017) data. We use the synthetic spectra library from Bestenlehner et al. (2014) to derive stellar parameters and BONNSAI (Schneider et al. 2014) to determine stellar masses and ages. The goal is to study the high-mass initial mass function, the recent star-formation history, the radiative feedback and the wind and mass-loss properties of the most massive stars in the core of R136.
