SUMMARY:Gamma rays from Young Stellar Objects 
DESCRIPTION:Gamma rays from Young Stellar Objects \nDr. Pere Munar\n\nIn th
 e last years star-forming regions and massive protostars have been  sugges
 ted to be gamma-ray emitters. Isolated massive protostars present  powerfu
 l outflows interacting with the surrounding medium. Some of these  sources
  power non-thermal radio jets, indicative of particle  acceleration up to 
 relativistic energies. At the jet-termination region  strong shocks form w
 hich can lead to gamma-ray emission, as theoretical  models predict. It ha
 s also been prognosticated that the combined effect  of several low-mass p
 rotostellar objects may produce significant amount  of gamma rays. We pres
 ent here two studies: IRAS 16547- 4247, an  isolated protostar showing non
 -thermal radio emission; and Monoceros R2,  a star forming region coincide
 nt with a source of the 2nd Fermi-LAT  catalog. In the first case, we anal
 ized archival X-ray data and detected  the source. We also studied the sys
 tem in a broad- band one-zone model  context and tried to fit the X-ray de
 tection with a non-thermal model.  In the second case, we analyzed 3.5 yea
 rs of Fermi-LAT data and  confirmed the source with a detection above 12 s
 igma. Our results are  compatible with the source being the result the com
 bined effect of  multiple young stellar objects in Monoceros R2.
