“Crystallized white dwarf stars in scalar-tensor gravity”


címmel tartandó szemináriumára.


Kivonat:



White dwarfs are the final evolutionary stage of stars with a mass lower than 
approximately ten solar masses, thus about 97% of the stars in the Milky Way, 
and in particular, our Sun. Even though their evolution is simple in 
comparison to other astrophysical objects, it involves several different 
physical processes under extreme conditions. Hence, they present a 
possibility to discover new phenomena and test current physical models, 
including gravity theories. In this talk I will give a brief introduction to 
scalar-tensor theory, followed by a discussion of white dwarf structure 
therein as well as differences to GR. The main part of the talk will focus on 
a toy model describing the cooling process that determines a white dwarf’s 
age. Finally, I will give an outlook on ongoing and possible future work.
