Maria Bergemann, astrophysicist at the Max Planck Institute for Astronomy in Heidelberg (Germany), is one of the invited professors at the XXIX Canary Islands Winter School of Astrophysics organized by the Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of La Laguna (ULL). Her classes will be about a very specific type of stars, which are characterized by their temperature, called "late-type stars" and the phenomena and physics that govern them, as well as the challenges posed by these stars from the point of view radiative transport, main topic of the School in this edition.
“The basic astrophysical parameter, which distinguishes ‘late-type’ stars from ‘early-type’ stars is their surface temperature”
“In radiative transfer modelling of late-type stars, the major challenge is to combine consistently their subsurface convection and the densities in the surface layers”
“The solution of the gender equality problem begins with its awareness”
Question: When we think of a star, we use to imagine an object similar to the Sun in size, temperature and composition. This type of “normal” star, however, is not the most common in the Universe: there are dwarfs and giants, reds and blues, so what is a late-type star?
Answer: The definition

NBIA Colloquium by Maria Bergemann
All you wanted to know about stars but were afraid to ask
Speaker: Maria Bergemann (MPI for Astronomy in Heidelberg & NBIA)
Abstract: The Milky Way galaxy is host to a few hundred billion stars. Of them, only about 10 million, less than %, have so far been mapped by large-scale spectroscopic surveys. Major progress in the quantity and/or quality of data is expected with next generation astronomical this colloquium, I will focus on the frontiers in stellar physics. First, I will give a general overview of the role of stars in modern astrophysics. I will then summarize the physical principles behind models that allow us to extract physical parameters of stars from their observed spectra. 3D non-equilibrium models are poised to become workhorses of astronomy in the next decade. Also other techniques, such as interferometry and asteroseismology, yield complementary constraints on stellar y, I will demonstrate how new data and new models drive progress in the areas that rely on stellar parameters and chemical composition of stars. These include studies of exoplanets and protoplanetary discs, nucleosynthesis and first stars, gravitational wave sources, and Galaxy formation.
