The Fundamental Parameters of Very Low Mass Stars


Very Low-Mass stars (M dwarfs) play a crucial role in exploring the low-mass 
end of the main sequence, extending down to the hydrogen burning limit. They 
constitute the predominant stellar component of the Galaxy, representing the 
majority of baryonic matter in our Galactic system. Additionally, many M 
dwarfs are now known to be hosts for exoplanets, including super-Earth 
exoplanets. The accurate determination of fundamental parameters for M dwarfs 
holds significant implications for stellar and Galactic astronomy and 
planetology. Despite their abundance in the Galaxy, M dwarfs pose challenges 
as elusive objects, and modelling their photosphere has been a persistent 
challenge, involving issues such as molecular opacities and dust cloud 
formation. Describing these stars necessitates a robust empirical foundation 
or validation. This presentation will explore various methods, strengths, and 
limitations in determining the fundamental stellar parameters of Very 
Low-Mass stars (M dwarfs).

The seminar will be held live in the Detre hall with audience, but also 
streamed online via Zoom. If you are unable to attend the presentation in 
person, you can join us via this link
