Abstract:
The importance of the physical environment in the evolution of newly
formed low-mass stars remains an open question. In particular,
radiation from nearby more massive stars may affect both the physical
and chemical structure of these kinds of young stars.
We constrain the physical characteristics of a group of embedded
low-mass protostars in Corona Australis in the vicinity of the young
luminous Herbig Be star R CrA.
Description:
The data are spectral data cubes (channel maps) of each spectral line
as listed below, using a combination of the Submillimeter Array (SMA)
and Atacama Pathfinder Experiment (APEX). The SMA data were reduced
using MIRIAD, and the APEX data using CLASS. The data were combined
using MIRIAD. For details, refer to paper.
