Radiation Processes in Astronomy - Radiative Processes in Astronomy: L16b - Thermal Bremsstrahlung

This lecture goes through thermal bremsstrahlung. We start with a derivation in the classical limit, then show how we obtain emission and extinction coefficients suitable for our radiative transfer, and finally use this for applications toward understanding the shape of the bremsstrahlung frequency-spectrum and estimation of the mass density in an ionised astrophysical nebula. Course: Radiation Processes in Astronomy Lecturer: Prof. Jon Sundqvist Programme: KU Leuven Bachelor Physics & Master Astronomy & Astrophysics #astrophysics #astronomy #education I record lectures live and place them here un-edited, in the hope that it will provide a more authentic feeling of the sort: "we're doing the actual work here and now". So like I keep telling students in the classroom: whenever you discover me doing some error let me know directly; for this channel this means make a comment on the videos. Then we can have a look at it, and thereby learn nicely from each other as we continue to develop our knowledge.
