ALMA Reveals Footprints of Baby Planets in a Gas Disk
Charlottesville VA (SPX) May 26, 2016
New analysis of ALMA data for HL Tauri provides yet more firm evidence of baby planets around the star. Researchers uncovered two gaps in the gas disk around the star. The locations of these gaps in the gas match the locations of gaps in the dust found in the ALMA high resolution image taken in 2014. This discovery supports the idea that planets form in much shorter timescales than previously thought and prompts a reconsideration of alternative planet formation scenarios. In November 2014, ALMA re ... read more
