A Study of the Energy Sources of Herbig—Haro Objects

We make a statistical study of the energy sources of high-velocity phenomena, Herbig-Haro(HH) objects. IRAS counterparts of HH objects are identified. Their colors, brightness, geometric relation to the HH objects and SED are analysed. The sources are found to be concentrated in a band-shaped region...

Description
Summary:We make a statistical study of the energy sources of high-velocity phenomena, Herbig-Haro(HH) objects. IRAS counterparts of HH objects are identified. Their colors, brightness, geometric relation to the HH objects and SED are analysed. The sources are found to be concentrated in a band-shaped region in the IRAS color-color diagram. We suggest an explanation of thick surrounding material for this distribution. We propose a new method for indenfifying the energy sources based on color and brightness. This method is applied to more than 200 HH objects whose energy sources are still unknown. Finally, a group of very young stellar object candidates which have similar properties to HH energy sources is picked out. Their harge-scale distribution is discussed.
