Abstract of the Rosseland Lecture

Dust grains are found everywhere in the space between the stars in galaxies. They are responsible for the formation of molecular hydrogen and for absorbing and re-emitting about 50% of the energy from all galaxies, as well as providing an effective coolant for star formation. Although important in various astrophysical processes, the origin and consequently the chemical make-up and emission properties of dust grains is largely unknown. Dust is generally believed to form in the atmospheres of low/intermediate-mass stars late in life, but there is growing evidence that dust may also be formed in the explosions of massive stars and/or be accreted in large amounts in the interstellar medium.


The Rosseland Lecture is held annually by the Institute of Theoretical Astrophysics of the University of Oslo in memory of Norway’s foremost astrophysicist, and founder of our institute, Professor Svein Rosseland (1894 – 1985). The Rosseland Lecturers are internationally renowned, outstanding astrophysicists. The Rosseland Lectures hold a semi-popular level and are open for all.

 

Coffee and cake are served from 03:00 PM.
