Infrared Observations of New Cometary Nebulae

Abstract: An infrared photometric survey of small nebulae selected from the Palomar Sky Survey prints reveals that long wavelength radiation 10 f¿) is only detected from those objects with "cometary" morphology. The structure of the nebulae and the infrared properties of their associated stars suggest that cometary nebulae are young stars surrounded by a disk-like distribution of dust, which may be viewed at various inclinations.

“…V380 Ori exhibits an SED that declines toward longer wavelengths, with an index characteristic of Class II sources. OSCIR mid-IR photometry for V380 Ori shows significant discrepancies with previous observations by Cohen (1973) and Berrilli et al (1987). Extensive near-IR observations of this object have shown $0.2 mag variability (Carpenter et al 2001) and constrained the angular size of the emission to within 1 AU of the star (Millan-Gabet et al 2001).…”

“…The source is associated with a bipolar Herbig-Haro outflow, as well as several near-IR companions (Staude & Neckel 1992;Li et al 1994). Mid-IR photometry shows a flat energy distribution characteristic of Class I PMS objects (Cohen 1974).…”

“…The H 2 emission structure can be conveniently divided into a number of distinct regions, as outlined in Fig. 2 The morphology of the infrared molecular hydrogen emission differs somewhat from the 'cometary' nature displayed in the optical (Cohen 1974), and from the broadband infrared and radio continuum images of López et al (1988). Instead of a cone, the appearance is one of two incomplete, but overlapping, arcs.…”
