Dissecting the chemical and physical structure of pre-stellar cores
Pre-stellar cores are starless cores that are gravitationally bound, dynamically evolved and on the verge of gravitational collapse. They evolve towards a higher central condensation leading to formation of the central protostar. There is observational evidence that the chemistry does not undergo a complete reset with the formation of the protostar, and hence pre-stellar cores provide the budget of matter that will eventually be inherited by stars and planets.
The physics and chemistry of pre-stellar core are deeply interconnected. In my talk I will discuss our recent results on using pre-stellar cores as "space laboratory" to study the physics and chemistry in the early stages of star formation. In particular, I will present our observational, modelling and laboratory efforts to use molecular spectra to dissect the physical and chemical structure of pre-stellar cores.
