At the meeting of the AAAS (American Association for the Advancement of Science) just concluded in Washington, D.C. the latest results were presented about the observations of the HD 142527 star system carried out with the ALMA radio telescope. It’s been an object of study by astronomers for some time and is particularly interesting because it’s very young. This means that around the central star there’s a ring of gas and dust that is probably forming one or more planets but there’s also a second star. This type of study will help to understand the formation of planets in binary systems.
