This week, January 13-18, 2014, features Niall Deacon. Niall is a postdoctoral astronomer working at the Max Planck Institute for Astronomy in Heidelberg, Germany. He specialises in using large scale surveys of the sky to identify failed stars called brown dwarfs to understand how they form and the processes which go on in their atmospheres. These objects are typically the same size as Jupiter but 12-80 times as massive and much hotter. They form a bridge between giant planets and stars helping us to learn more about both. Niall also is active in astronomy outreach, producing astronomy videos such as Don’t Call Me Colin and others. When not working, he is a keen pub quizzer, supports Scotland and Falkirk FC (so is used to seeing teams in dark blue lose) and hates referring to himself in the third person.
Starting Monday, follow along with astrotweeps on Twitter, Facebook, or right here on the Astrotweeps webpage.
