Hot cores in supernova remnant RX J1713.7-3946 exhibit column density ratios of complex organics, deuterated species, and S/N-bearing molecules that are indistinguishable from those in typical star-forming environments.
ALMA Band 6 data detect SiO emission and masers up to v=8 in AGB stars, showing clumpy distributions, velocity gradients, and a tentative link between emission radius and mass-loss rate.
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.
New ALMA data at 50 au resolution of HH46/47 shows a rotating-infalling envelope to disk transition at 30 au around a 0.3 solar-mass protostar, with outflow shells expanding radially and supporting entrainment over disk-wind origin.
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.
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}.
Abundance calculations for CaC_{2n+1}N (n=1-4) in IRC+10216 indicate observed CaNC originates from larger cyanopolyyne ions requiring molecular rearrangement during recombination.
C4H/H13CO+ and c-C3H2/H13CO+ abundance ratios decrease with molecular core evolution, indicating consumption of small unsaturated hydrocarbons into complex organic molecules.
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.
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.
