Summary of Research

  • My main research interest focuses in understanding the formation of high-mass stars. To develop a more robust theory of high-mass star formation, I consider that different aspects of the star formation processes need to be explored, characterized, and understood. The main questions that motivate my research in high-mass star formation are: what characterizes the early stages of high-mass star formation? What is the importance of magnetic fields in the formation of high-mass stars? How do high-mass binary systems form? Are there Keplerian disks around high-mass stars? What is the origin of the initial mass function (IMF)? To address all these questions, my main instrument for research is ALMA, but I have used al large amount of radio telescope around the world: SMA, VLA, CARMA, ATCA, Nobeyama, Mopra, APEX, ASTE, and GBT.
