800,000 sources in the Hubble Tarantula Treasury Project (HTTP)

19 Nov

The Tarantula nebula is a region of extreme star Screen Shot 2015-11-19 at 9.23.16 AMformation located in a satellite galaxy of our milky way. Sabbi and the HTTP team present the results from a treasure survey conducted with the Hubble Space Telescoope identifying the brightness, colors and positions of 800,000 sources, going down to subsolar masses. For this Hubble took images in 8 different filters from the near ultra violet to the near infrared

The HTTP catalogue is the richest sample of intermediate and low mass pre-main sequence candidates. It allows to study how star formation has been developing through the region and the dual role stellar feedback in quenching and triggering star formation.  The results have been accepted for publication in ApJS.
