. Proposal-for-the-30m-telescope-title, Didier Despois (FR) Proposal category: Standard Scientific category: High-mass star formation, Astrochemistry Total requested time: 27.2 (Emir) Abstract: We propose to finalize a spectral line survey of W43-MM1 and DR21-OH with the IRAM 30m/EMIR to investigate the formation and early evolution of hot cores in the context of probing the process at the origin of complex molecules in hot cores. Such young massive objects are great targets to investigate warm grain chemistry and have been missed so far for unbiased spectral surveys (in ASAI for instance). They will complement deep and extensive work done towards SgrB2 with ALMA, Complex molecules in young hot cores: W43-MM1 and DR21-OH PIs: Sylvain Bontemps (FR) CoIs: Nathalie Brouillet (FR), Frederique Motte (FR), Jordan Molet (FR), Thomas Nony (FR)

, As part of this project, we collected some parts of the millimeter spectrum of the reference source DR21-OH (for calibration reason, DR21-OH is a line calibration source) and of W43-MM1 (one of the most extreme IR-quiet massive clump of the Galaxy) during the 2h of Cygnus X transits above 80deg which were lost for CygX-N63 observations. In the meantime, our group obtained ALMA observations of W43-MM1 (Motte et al.) with 8 spectral windows around 230 GHz observed at high spatial resolution, Proposal history: We obtained between 2012 and 2014 with the IRAM 30m, pp.132-144

, We will reduce data following the strategy of our past Cycle projects, aiming to minimize interferometric artefacts while keeping low-mass cores: most sensitive self-calibration, combination with ACA and multi-scale cleaning. We will then extract cores with Getsources (Men'shchikov et al. 2012), simultaneously on the full and line-free continuum bands for detecting both low-mass and hot core sources. Several runs will be done to determine the robustness of the extracted CMF shape and its completeness level, ALMA images (WG1 & WG2)

, The pre-stellar, protostellar, or HII region nature of cores will be investigated through outflows imaged in CO, SiO, and SO lines, through hot cores traced by complex organic molecules (see Fig. 1a), and through H41? recombination line. The evolutionary stage of protoclusters will be estimated from the typical age of its massive cores: 10 6 yr for HII regions and 10 5 yr for protostars, Core nature and massive protocluster evolutionary stage (WG3)

, We will use 1 mm fluxes in the first place but 3 mm fluxes when the former is optically thick. Fluxes will be corrected for line or free-free contaminations, using line-free bands and radio (archival and GLOSTAR project from Menten) plus ALMA 3 mm fluxes. We will build dust temperature models dedicated to cores using the combination of 1) a Bayesian SED fitting method applied to all existing continuum images including ALMA (PPMAP; Marsh et al. 2015) and 2) hot core temperatures measured through line excitation temperatures of complex organic molecules, Core mass determination (WG4): A good mass determination is a pre-requisite for a proper CMF

, CMFs of prestellar (and IR-quiet protostellar) cores will be compared with IMF models of binaries/systems, CMF evolution (WG5 & WG9), 2013.

&. Hennebelle and . Chabrier, Our requested sensitivities (see Table 1) will allow a 5? detection of cores down to the CMF peak, 0.6 M ? when assuming T dust = 20 K. For 'Young' massive protoclusters, we will use the much larger statistics (8?) of ALMA-IMF to definitively determine whether the low-mass part of their CMFs is flatter than the IMF. CMF evolution through protocluster age will. also be investigated by averaging the CMF, Könyves et al. 2015) and extragalactic environments, 2013.

G. Csengeri, 2013) will be quantified to check if gas feeding can explain a CMF that reconciles the IMF shape at late stages. Outflowing gas mass will also be measured by 12 CO line wings to estimate the mechanical feedback of outflows as proposed by, Ginsburg, Sanhueza, & Louvet WG1: Data reduction Galván-Madrid, Lopez-Sepulcre, Louvet, Sanhueza WG2: Core extraction Bontemps, vol.48, p.5, 2000.

, 3 The velocity dispersion relates to the FWHM of the lines as ? = F W HM

, Therefore we request four times better angular resolution than our Cycle~2 data, i.e. 0.1'' or 550~AU at 5.5~kpc. The target has a total size of ~60'', and we will merge the cycle 7 data with previous data (that span the 0.4'' up to 60'' range). The desired configuration (C43-8resolution (see Fig. 1 Right), SiO outflows are highly collimated. Within the 4-resolution beam of our SiO(2-1) PdBI study (Louvet et al. 2016a), outflows thus correspond to resolved structures along their 0.1~pc extent and unresolved across their width. Observed SiO(2-1the low-and high-velocity components of outflows are expected, Our resolution and integration time is driven by the necessity to detect the weak outflows of the youngest high-mass protostars in W43-MM1
