Chamaeleon-MMS1 NH_3_ (1,1) and (2,2) maps
Listed in IVOA Registry (Virtual Observatory)
The aim of this study is to investigate the structure and kinematics of the nearby candidate first hydrostatic core Cha-MMS1.
Description
Cha-MMS1 was mapped in the NH_3_(1,1) line and the 1.2cm continuum using the Australia Telescope Compact Array, ATCA. The angular resolution of the ATCA observations is 7" (~1000AU), and the velocity resolution is 50m/s.
The core was also mapped with the 64-m Parkes telescope in the NH_3_(1,1) and (2,2) lines. Observations from Herschel Space Observatory and Spitzer Space telescope were used to help interpretation. The ammonia spectra were analysed using Gaussian fits to the hyperfine structure.

A two-layer model was applied in the central parts of the core where the ATCA spectra show signs of self-absorption.
