Spectacular Hubble Space Telescope Observations of the Coma Galaxy D100 and Star Formation in Its Ram Pressure-stripped Tail

Popis výsledku v původním jazyce

We present new HST F275W, F475W, and F814W imaging of the region of the Coma cluster around D100, a spiral galaxy with a remarkably long and narrow (60 x 1.5 kpc) ram pressure-stripped gas tail. We find blue sources coincident with the Ha tail, which we identify as young stars formed in the tail. We also determine they are likely to be unbound stellar complexes with sizes of similar to 50-100 pc, likely to disperse as they age. From a comparison of the colors and magnitudes of the young stellar complexes with simple stellar population models, we find ages ranging from similar to 1 to 50 Myr and masses ranging from 10(3) to similar to 10(5) M-circle dot. We find that the overall rate and efficiency of star formation are low, similar to 6.0 x 10(-3) M-circle dot yr(-1) and similar to 6 x 10(-12) yr(-1), respectively.
