Spectroscopic Survey of H{\alpha} Emission Line Stars Associated with
  Bright Rimmed Clouds
  The results of a spectroscopic survey of H alpha emission line stars
associated with fourteen bright rimmed clouds are presented. Slit-less optical
spectroscopy was carried out with the Inter University Centre for Astronomy and
Astrophysics (IUCAA) 2m telescope and IUCAA Faint Object Spectrograph and
Camera (IFOSC). H alpha emission line was detected from 173 objects. Among them
85 objects have a strong H alpha emission line with its equivalent width larger
than 10 A. Those are classical T Tauri stars. 52 objects have a weak H alpha
emission line with its equivalent width less than 10 A and do not show
intrinsic near-infrared excess. Those are weak-line T Tauri stars. On the other
hand, 36 objects have a weak H alpha emission line (<10 A), although they show
intrinsic near-infrared excess. Such objects are not common in low-mass star
forming regions. Those are misfits of the general concept on formation process
of a low-mass star, in which it evolves from a classical T Tauri star to a
weak-line T Tauri star. Those might be weak-line T Tauri stars with a flared
disk in which gas is heated by ultraviolet radiation from a nearby early-type
star. Alternatively, we propose pre-transitional disk objects as their
evolutional stage.
