An artist impression of HD 142527 based on ALMA data. According to astronomers, HD 142527 consists of a main star a little more than twice the mass of our Sun and a smaller companion star only about a third the mass of our Sun; they are separated by approximately one billion miles. The rendition shows a distinctive arc of dust (red) embedded in the protoplanetary disk. The red arc is free of gas, suggesting the carbon monoxide has frozen out, forming a layer of frost on the dust grains in that region. Astronomers speculate this frost provides a boost to planet formation. The two dots in the center represent the two stars in the system. Image credit: B. Saxton / NRAO / AUI / NSF.
