24. Organic and inorganic molecules in protostellar cores in the outer Galaxy and the Magellanic Clouds

Nearby low-metallicity laboratories, such as the outer part of the Galaxy, as well as the Large and
Small Magellanic Clouds (x0.1-0.5 solar metallicity), are excellent targets to study the star-forming
“core”-scale chemical phenomena, such as the formation of complex organic molecules, in different
environments. In the last decade, there has been a great progress in astrochemical studies...

25. Isotopic abundance ratios: What’s up in the outer edge of the Milky Way?

Isotopic ratios (e.g. 12C/13C and 14N/15N ratios) measured within interstellar molecular clouds
depend on the chemical evolution of the galaxy due to stellar nucleosynthesis, and thus they can
provide unique constraints to the history of star formation in galaxies. Moreover, isotopic ratios
also depend on local chemical fractionation effects, which are closely connected to the...

51. Molecular abundances in the outer Galaxy and their relation with the Galactocentric distance

Diego Gigli (Istituto Nazionale di Astrofisica (INAF))

The outer Galaxy is characterized by a sub-Solar metallicity that decreases with increasing distance from the Galactic center. Therefore, molecule formation and survival processes in star-forming regions within the inner and outer Galaxy are expected to differ and may depend on the Galactocentric radius. To better understand how chemistry evolves throughout the Milky Way and how star formation...

27. Disks at low metallicities

Anna McLeod (Durham University)

12/11/2024, 11:45

Over the past decade, technological advancements have enabled spatially resolved studies of disks around young stars at larger and larger distances, opening up studies of these objects in environments that differ from those of the Solar neighborhood, and culminating in the recent discovery of a Keplerian disk around the driving star of HH 1177, a massive young stellar object (MYSO) in the...

1. Isotopic abundance ratios: What’s up in the outer edge of the Milky Way?

Laura Colzi (Centro de Astrobiologia (CAB), CSIC-INTA)

Isotopic ratios (e.g. $^{12}$C/$^{13}$C and $^{14}$N/$^{15}$N ratios) measured within interstellar molecular clouds depend on the chemical evolution of the galaxy due to stellar nucleosynthesis, and thus they can provide unique constraints to the history of star formation in galaxies. Moreover, isotopic ratios also depend on local chemical fractionation effects, which are closely connected to...
