Description
IRAS18162-2048 is a massive protostar located at a distance of 1.4 kpc that powers the largest and fastest protostellar jet known in the Galaxy. It has been the target of numerous studies as it constitutes a prime example for investigating the presence of disks and jets associated with high mass protostars. In this contribution I will present the results extracted from deep sub- arsecond observations towards the heart of IRAS18162-2048 carried out with the Very Large Array. I will explore the properties of the jet down to disk-scales in order to investigate its ejection mechanism. Ultimately, this will shed light on the mass-loss processes that massive stars undergo during their earliest satges of formation.
