| Abstract: |
T-dwarfs are amongst the coolest compact objects directly observable outside our Solar System,
and a critical means of probing star formation processes at very-low masses.
Corona Australis is a young (3–15Myr), nearby (130pc) star forming region,
and an ideal location in which to search for very cold T-type brown dwarfs.
Methane imaging provides several advantages in searching for such objects — most
critically that T-dwarfs are the only stellar objects expected to show blue
colours in specially designed sets of methane filters. Surveys of this nature are important as they
provide a direct means to answer fundamental questions — “Is there a minimum
mass for star formation?” and “Is there a universal cluster mass function?”. |
