As a part of our on-going program to study star formation under various environments, we present preliminary results from our multi-wavelength study of a bright-rimmed cometary globule complex, CG4/6/SA101 in the Gum Nebula. These cometary clouds are photo-evaporating due to UV radiation from neighboring O stars (10 < d < 100 pc) in the Vela OB2 association. The intermediate and low-mass stars in these cometary clouds form in an environment that differs from both the quiet isolation of young stars in T-associations such as Taurus and the violently energetic environment like that of the Orion Nebula cluster (ONC). The moderate separation between the cometary clouds and the O stars creates a radiation environment that has an intensity intermediate between the Taurus and Orion star forming regions. Circumstellar material and accretion disks may last longer than those in ONC, yet may not survive as long as they would in an isolated region such as Taurus or TW Hya. We compare our results with other star forming regions under different environments.
