We present photometric and spectroscopic results for the low mass pre-main sequence ( PMS ) stars with spectral types K – M in the cometary globule ( CG ) 30/31/38 complex .
We obtained multi-object high resolution spectra for the targets selected as possible PMS stars from multi-wavelength photometry .
We identified 11 PMS stars brighter than V = 16.5 with ages \lesssim 5 Myr at a distance of approximately 200 pc .
The spatial distribution of the PMS stars , CG clouds , and ionizing sources ( O stars and supernova remnants ) suggests a possible triggered origin of the star formation in this region .
We confirm the youth of the photometrically selected PMS stars using the lithium abundances .
The radial velocities of the low mass PMS stars are consistent with those of the cometary globules .
Most of the PMS stars show weak H \alpha emission with W _ { \lambda } ( H { \alpha } ) < 10Ã .
Only 1 out of the 11 PMS stars shows a moderate near-IR excess , which suggests a short survival time ( t < 5Â Myr ) of circumstellar disks in this star forming environment .
In addition , we find five young late type stars and one Ae star which have no obvious relation to the CGÂ 30/31/38 complex .
We also discuss a possible scenario of star formation history in the CGÂ 30/31/38 region .
