Abstract:
We focus on the kinematical properties of a proto-binary to study the
infall and rotation of gas toward its two protostellar components.
We present ALMA Science Verification observations with high-spectral
resolution of IRAS 16293-2422 at 220.2GHz. The wealth of molecular
lines in this source and the very high spectral resolution offered by
ALMA allow us to study the gas kinematics with unprecedented detail.
Description:
IRAS16293ALMA220GHz_continuum.fits and
IRAS16293ALMA220GHz_cube.fits are the FITS files containing the
entire data cube and continuum map, respectively, obtained from the
ALMA Science Verification program.
