Sabbi and the HTTP Team Space Telescope Science Institute – 3700 San Martin Dr. 21218, Baltimore, MD USA e-mail: [email protected] Abstract. We present results from the Hubble Tarantula Treasury Project (HTTP), a Hubble Space Telescope panchromatic survey (from the near UV to the near IR) of the entire 30 Doradus region down to the sub-solar (∼ 0:5 M ) mass regime. The survey was done using the Wide Field Camera 3 and the Advanced Camera for Surveys in parallel. HTTP provides the first rich and statistically significant sample of intermediate- and low-mass pre-main se- quence candidates and allows us to trace how star formation has been developing through the region. We used synthetic color-magnitude diagrams (CMDs) to infer the star formation his- tory of the main clusters in the Tarantula Nebula, while the analysis of the pre-main sequence spatial distribution highlights the dual role of stellar feedback in quenching and triggering star formation on the giant Hii region scale.

The observations provide an unprecedented spectroscopic census of the massive stars and ionised gas in the vicinity of R136, the young, dense star cluster located in NGC 2070, at the heart of the richest star-forming region in the Local Group. Spectrophotometry and radial-velocity estimates of the nebular gas (superimposed on the stellar spectra) are provided for 2255 point sources extracted from the MUSE datacubes, and we present estimates of stellar radial velocities for 270 early-type stars (finding an average systemic velocity of 271 ± 41 km s−1).
