Galactic and extragalactic star-forming regions
Thursday, 6th November 2025, 12:00 (CET) (Auditorio/Zoom)
Most
stars, including the Sun, are born in
large stellar clusters that contain
massive stars. Therefore, the study of
the chemical content of these regions is
crucial to understand the basic chemical
ingredients available at the dawn of
planetary systems. This will inform us
whether our Solar System - the only one
in which we know life is present - was
chemically unique, or alternatively, if
the basic molecular building blocks of
life are widespread in our Galaxy, and
even in other galaxies.
To address this, we first study in
detail the hot core in the high-mass
star-forming region G31.41+0.31 to
explore the available chemistry when our
Solar System was born, and we compare it
with other sources representing
different stages of stellar system
formation. Secondly, we examine the
chemical inventory present also in the
same region, but with different physical
conditions: a shock-affected region, in
which the molecules we detect are less
influenced by nearby stellar heating.
Finally, we extend our study beyond our
Galaxy by examining the central part of
the nearby galaxy NGC 253, to understand
whether the chemical composition of the
Milky Way is also representative of
those in external galaxies.
