Being the stripped cores of red giants, hot subdwarf stars turned out to be important markers of peculiar events in stellar evolution ranging all the way from binary star or star-planet interactions to the progenitors of supernovae Ia explosions used to measure the expansion of our Universe. Significantly enhancing the known sample using data from the Gaia mission we will perform the first comprehensive study of this population.
