Dr. Jorge Morales Ortiz, University of Puerto Rico at Río Piedras, Survey of outflow-envelope interactions in low-mass protostars in the Orion A molecular cloud, This project will provide an unprecedented observational dataset that will be used to study the evolution of the dense circumstellar gas associated with the star formation process. The low-mass protostars in the dataset were chosen because they are located in the same molecular cloud, which ensures a consistent resolution in the ALMA observations and the existence of the same ancillary data for all of them, therefore guaranteeing a consistent analysis. The rich dataset, which will allow us to address the challenges previously described, are essential steps to understanding the star formation efficiency in molecular cloud cores and the origin of stellar masses. jorge.morales15@upr.edu
