description Chamaeleon II Cloud Overview
The Chamaeleon II Cloud, often abbreviated Cha II, is a dark molecular cloud and low-mass star-forming region in the Chamaeleon complex. An Atacama Large Millimeter/submillimeter Array survey examined 29 protoplanetary disks in the region and detected 22 sources in 1.3-millimetre continuum emission. These observations make the cloud a subject for studying disk dust and the early environments of young stars.
help Chamaeleon II Cloud FAQ
What is the Chamaeleon II Cloud?
The Chamaeleon II Cloud, often abbreviated Cha II, is a dark molecular cloud and low-mass star-forming region. It is part of the larger Chamaeleon complex.
What did the ALMA survey find in Chamaeleon II?
An Atacama Large Millimeter/submillimeter Array survey examined 29 protoplanetary disks in the region. It detected 22 sources at a wavelength of 1.3 millimetres.
Why do astronomers study the Chamaeleon II Cloud?
Its cold molecular material and young stars make it useful for studying low-mass star formation and planet-building disks. The ALMA observations provide millimetre-wave data from those disks.
What does Cha II stand for?
Cha II is the common abbreviation for the Chamaeleon II Cloud. It identifies one part of the Chamaeleon star-forming complex rather than a planet or individual star.
