Notes. (2)–(5) Luminosity peak name, integrated luminosity, and mean FWHM size. Values are taken or computed from Table B.1 of Dell’Ova et al. (2024). The luminosity peak with a † tag is common to the W43-MM2 and W43-MM3 regions; we characterized it only once, in W43-MM3. (6) Presence or absence of a temperature peak detected in the ellipse describing the FWHM of the luminosity peak. (7)–(8) Protostellar cores associated with the luminosity peak of Col. 2 have their centers inside the ellipse describing the FWHM of the luminosity peak. ID numbers and FWHM angular sizes of protostellar cores are taken from the catalogs of Nony et al. (2023) and Pouteau et al. (2022) (see Sect. 2.1). Protostellar cores with a ⋆ tag are tentative. (9) Distance between the centers of the protostellar core and its host luminosity peak. (10) Temperature measured in the PPMAP dust temperature image, at core location, corresponding to the background-diluted core temperature, mass-averaged up to a 1.25″ radius (see Sect. 3.1). (11) Contribution level of each protostellar core to their associated luminosity peak, estimated in Sect. 4.3.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
