ACCRETION ONTO PLANETARY MASS COMPANIONS OF LOW-MASS YOUNG STARS

Measurements of accretion rates onto planetary mass objects may distinguish between different planet formation mechanisms, which predict different accretion histories. In this Letter, we use Hubble Space Telescope (HST)/WFC3 UVIS optical photometry to measure accretion rates onto three accreting obj...
