Revisiting G29.862-0.0044: A jet cavity disrupted by an outflow in a likely young stellar object wide binary system

A few years ago, we investigated the massive young stellar object (MYSO) G29. 862-0. 0044 (YSO-G29), an intriguing star-forming region at a distance of 6. 2 kpc. Although the typical disc-jet scenario was proposed to explain the observations, it remained far from conclusive. We wonder if the puzzling observed near-IR features are produced by only one source or if it is due to confusion generated by an unresolved system of YSOs. Unveiling this issue is important for a better understanding of the star-forming processes. We analysed YSO-G29 using new observations in the near-IR from Gemini-NIFS at the radio continuum (10 GHz) from the Jansky Very Large Array (JVLA) and new continuum (1. 3 mm) and molecular line data from the Atacama Large Millimeter Array (ALMA). The near-IR observations allowed us to detect emission of H₂ 1–0 S (1) and Brγ lines in YSO-G29, which are compatible with excitation and ionisation from UV radiation propagating in a highly perturbed ambient. In addition, we also found some evidence of H₂ excitation by collisions. The ALMA data show the presence of a conspicuous and collimated molecular outflow propagating southwards, while to the north, an extended molecular feature perfectly surrounded by the Ks near-IR emission appears. The continuum emission at 1. 3 mm allowed us to better resolve the molecular cores, one of which stands out due to its high temperatures and rich chemical composition. From the JVLA observations, we discovered a compact radio continuum source, a likely compact region or an ionised jet of a massive protostar, located at ∼0 (∼0. 02 pc) from the main millimetre core. In this way, we propose a YSO wide binary system. We can explain the nature of the intriguing near-IR features previously observed: Cone-like structures produced by jets or winds of one of the components of the binary system that cleared out the surroundings were disrupted by a molecular outflow probably from the other component. These results complete the picture of what is happening in YSO-G29 and reveal a phenomenon that should be considered when investigating massive star-forming regions.
