Abstract / Description:A deep [S II] lambdalambda6717/6731 wide-field
survey of Herbig-Haro (HH) objects has been
carried out in two fields toward the R CrA
molecular cloud using the ESO/MPG 2.2 m Wide
Field Imager. Twelve new HH objects, many of
which consist of several condensations or knots,
have been discovered, and new details of the
known HH objects have been revealed. Combining
the results of previous optical, infrared, and
millimeter-wavelength observations, the possible
exciting sources of HH objects in the region are
discussed. On the basis of the previously known
and newly discovered HH objects, at least five HH
flows in the region around R CrA and at least
two outflows in the region around VV CrA can be
identified. In combination with the previously
detected molecular outflows, the HH flows in the
R CrA region indicate rather active star
formation in the R CrA core in the past
105-106 yr.
