Serendipitous discovery of a bound nine-member protostellar system in NGC 6334-43 formed by filament fragmentation, with outflows from two sources and virial masses derived for three cores.
LTE analysis of ALMA data for AG318-c9 yields molecular parameters and spatial maps for three COMs, compared to G31 as a line-identification template for the ALMAGAL survey.
ALMA survey detects H2CO in 45% of 20 disks and finds strong correlations of line luminosity with disk size, mass, and stellar luminosity, suggesting grain-surface formation.
The CH₃OH/CH₃CN ratio in the S68N outflow is constant at ~100-200 and matches gas-phase astrochemical models only when cosmic-ray ionization rates are raised to ~10^{-14} s^{-1}.
New spectroscopic measurements of 13CH3CN and CH3^13CN up to v8=2 yield precise l-component energy spacings of 22.93 and 21.79 cm^{-1} from perturbations and enable targeted searches in star-forming regions.
ALMA survey detects hot corino chemistry in 3/5 Class 0/I protostars with CH3OH column densities 10^17-10^18 cm^{-2} and rotational temperatures 200-250 K, showing two orders of magnitude variation in COM ratios.
UCLCHEM 4.0 is an updated open-source framework that solves time-dependent gas-grain chemical networks with built-in parametrizations for cloud collapse, cores, and shocks.
This review chapter discusses open questions on protoplanetary disk substructures and how SKA-Mid continuum observations at 12.5 GHz can help resolve them.
