Scientific paper

A search for embedded heat sources in an extended region of enhanced CO(12) emission in the bright-rimmed molecular cloud Barnard 35 was performed by means of a deep two micron-wavelength infrared survey. Twelve infrared sources were detected, and optical spectra were obtained. One of the two H alpha emission-line Orion population star sources detected had been previously classified as Ge alpha. No evidence was found for an embedded population of either early or intermediate type stars in the cloud. It is concluded that the passage of an ionization-driven shock or the release of internal magnetic energy via the viscous dissipation of Alfven waves following cloud compression are possible heating sources for B35.
