Resumen

Recent dust continuum surveys have shown that filamentary structures are ubiquitous alongthe Galactic plane. While the study of their global properties has gained momentum recently,we are still far from fully understanding their origin and stability. Theories invoking magneticfield have been formulated to help explain the stability of filaments; however, observations areneeded to test their predictions. In this paper,we investigate the structure and radial equilibriumof five filamentary molecular clouds with the aim of determining the role that magnetic fieldmay play. To do this,we use continuum and molecular line observations to obtain their physicalproperties e.g. mass, temperature and pressure. We find that the filaments have lower linealmasses compared to their lineal virial masses. Their virial parameters and shape of their dustcontinuum emission suggests that these filaments may be confined by a toroidal dominatedmagnetic field.Nota general
