13. 13 ANASAC Meeting – May 20, 2015 Long Baseline Campaign: HLTau Young Star ~1 Million Years One of the nearest star forming regions to Earth (~450 light yr) Resolution is 5 AU Gaps almost certainly reflect young planets Comparison to Hubble shows ALMA’s power! Presence of several planets at such a young age is “disturbing” to planet formation theories ALMA Partnership, Brogan et al. 2015
