Program: GN-2016A-FT-3

This is a short, self-contented project to observe Leo P - the most metal poor yet star-forming galaxy in the local volume - which can serve as the local counterpart to interpret the properties of distant galaxies in the early universe. Deep NIR photometry of Leo P will reveal its AGB stars, the major contributor of dusts, and helps us to understand the dust formation process in very low metallicity environments similar to the early universe. Since AGB stars are at an evolved stage, they can shed lights on the spatial distribution of old and intermediate populations, thus provide insights on the star formation history at the early epoch of Leo P. Further more, the ratio of C−rich and O−rich AGB stars can be indicators of on−site metallicity and provide us the global picture of metallicity distribution in Leo P.
