The infrared eye of the wide-field camera 3 on the Hubble Space Telescope reveals multiple main sequences of very low mass stars in NGC2808
We use images taken with the infrared channel of the Wide Field Camera 3 on the Hubble Space Telescope to study the multiple main sequences (MSs) of NGC2808. Below the turnoff, the red, the middle, and the blue MS, previously detected from visual-band photometry, are visible over an interval of about 3.5 F160W magnitudes. The three MSs merge together at the level of the MS bend. At fainter magnitudes, the MS again splits into two components containing ∼65% and ∼35% of stars, with the...[Show more]
