The star forming region around IRAS 05487+0255 encloses at least three
stellar jets which have some peculiar properties. Two of the jets are
not detected at optical wavelengths, but only in the near infrared
(2 micron) in molecular hydrogen. The brightest jet in the region
is detected in Halpha, [SII] 6731 and the molecular hydrogen lines, but
its source either is more than 100 arcseconds away or has not been
detected. Indeed to explain the turbulent optical morphology of HH 110
it has been suggested that the gas outflow originates farther away and
that it is undergoing a grazing collision with a molecular cloud.
Finally, the source for one of the molecular hydrogen jets seems to be
misplaced, given the low spatial IRAS resolution, and is invisible in the
K band.
The goal of this project is to map the IRAS 05487+0255 region using ISOCAM
to discover the true source of the HH 110 jet and the nature of the IRAS
emission. Maps will also be performed for the molecular hydrogen emission
to determine its relationshp with the nearby sources.
Two raster maps will be performed using a PFOV of three arcseconds.
One 2x2 map for two broad band filters, and another 3x3 map for two narrow
band filters. The experiment is designed to detect sources ten times
fainter than IRAS 05487+0255 in its neighborhood, and to map the
molecular hydrogen emission.
The total time including overheads for this observation is 2725secs.
