John Christopher Baillie Papaloizou FRS (born 1947) is a British

theoretical physicist Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experime ...

accretion disks An accretion disk is a structure (often a circumstellar disk) formed by diffuse material in orbital motion around a massive central body. The central body is typically a star. Friction, uneven irradiance, magnetohydrodynamic effects, and other fo ...

under the supervision of Roger J. Tayler. The title of his thesis is ''The Vibrational Instability in Massive Stars''. He discovered the Papaloizou-Pringle instability together with Jim Pringle in 1984. Papaloizou also made major contributions in various areas such as the radial-orbit instability, toroidal modes in stars and different instabilities in accretion disks. The asteroid 17063 Papaloizou is named after John Papaloizou.
