Dimitris Stamatellos is a Guild Research Fellow in Astrophysics at the Jeremiah Horrocks Institute. He is interested on how planets and low-mass stars form. He develops advanced computational hydrodynamic models to determine the properties of these objects.
The focus of Dimitri’s research has been the study of the formation of planets, brown dwarfs, and low-mass stars around Sun-like stars by disc fragmentation.
Dimitri’s work has been influential and highly cited. His paper, “The properties of brown dwarfs and low-mass hydrogen-burning stars formed by disc fragmentation” (2009, MNRAS, 392, 413) has appeared in the most cited paper list (2009-2011) that was compiled by the Monthly Notices of the Royal Astronomical Society. The same paper is among the top 1% most cited Astronomy papers in 2009 (from the Astrophysical Database System - ADS). This work has been based on a numerical method he developed, which incorporates the effects of radiative transfer in hydrodynamic simulations (this method has since been used by several research groups; eg, Edinburgh, St Andrews, Bonn, Beijing, Sheffield, Munich, UCL).
Dimitris also has a strong interest in the initial stages of star formation. He has worked in determining the observational characteristics of prestellar cores and young protostars hidden in their parent cores, using a 3D Monte Carlo radiative transfer code that he developed. He has been involved in major survey projects (eg, using space- and ground-bases observing facilities like HERSCHEL and SCUBA2).
