Title: Possible Existence of parallel-oriented molecular clouds in the Gould Belt.

Abstract: The Molecular Cloud, the incubator of stars, is one of the most influential components of galaxies. It evolves under three major roles: self-gravity, turbulence, and magnetic fields. Molecular clouds often possess filamentary structures, even though their shape is irregular in general. Intuitively, once the cloud structure is anisotropic, the effect of the magnetic field will depend on the orientation between the cloud and the mean field direction. The bimodal (parallel or perpendicular) cloud-field orientations, fragmentation rates, and star-formation efficiency of the 13 Gould Belt filamentary clouds led us to investigate whether any intrinsically parallel molecular clouds are present. We conducted magnetohydrodynamic (MHD) simulations and compared the likelihood to some statistical tests. In the talk, I will present the background and details of our project and discuss the future directions.
