Query: Accretion in low-mass members of the Orion Nebula Cluster with young
  transition disks   Although the Orion Nebula Cluster is one of the most studied clusters in the
solar neighborhood, the evolution of the very low-mass members ($M_* < 0.25 \,
M_\odot$) has not been fully addressed due to their faintness. Our goal is to
verify if some young and very low-mass objects in the Orion Nebula Cluster show
evidence of ongoing accretion using broadband VLT/X-Shooter spectra. For each
target, we determined the corresponding stellar parameters, veiling, observed
Balmer jump, and accretion rates. Additionally, we searched for the existence
of circumstellar disks through available on-line photometry. We detected
accretion activity in three young stellar objects in the Orion Nebula Cluster,
two of them being in the very low-mass range. We also detected the presence of
young transition disks with ages between 1 and 3.5 Myr.
