PI: Dr. Raghvendra Sahai Jet Propulsion Laboratory Y CoI: Dr. Mark Claussen Associated Universities, Inc. N CoI: Dr. Mark R. Morris University of California - Los Angeles N ------------------------------------------------------------------------------------ Abstract We propose to study the stellar embryos in select members of a newly recognized class of Free-floating Evaporating Gaseous Globules (frEGGS) embedded in HII regions and having head-tail shapes. We discovered two of these in the Cygnus massive star-forming region (MSFR) with HST, including one of the most prominent members of this class (IRAS20324). Subsequent archival searches of Spitzer imaging of MSFRs has allowed us to build a statistical sample of frEGGs. Our molecular-line observations show the presence of dense molecular cores with total gas masses of (0.5-few) Msun in these objects, and our radio continuum images and Halpha images (from the IPHAS survey) reveal bright photo-ionized peripheries around these objects. We hypothesize that frEGGs are density concentrations originating in giant molecular clouds, that, when subject to the sculpting and compression by strong winds and UV radiation from massive stars, become active star-forming cores. For the 4 frEGGs with HST or near-IR AO images showing young stars and bipolar cavities produced by their jets or collimated outflows, the symmetry axis points roughly toward the external ionizing star or star cluster - exciting new evidence for our overpressure-induced star formation hypothesis. We propose to test this hypothesis by imaging 24 frEGGs in two nearby MSFRs that represent different radiation-dominated environments. Using ACS imaging with filters F606W, F814W, & F658N (Ha+[NII]), we will search for jets and outflow-excavated cavities, investigate the stellar nurseries inside frEGGs, and determine whether the globules are generally forming multiple star systems or small clusters, as in IRAS20324. ------------------------------------------------------------------------------------ 15208( 3) - 11-Sep-2017 13:41:05 - [ 2] Observations Description ------------------------ We will image 24 frEGGs in 3 filters (F658N, F606W, F814W) using the ACS WFC. We prefer ACS to WFC3 because of ACS's higher sensitivity in the wavelength region of interest ($\sim$0.6\micron) and larger field-of-view ($202{''}\times202{''}$ compared to $162{''}\times162{''}$) which allows us to image a larger number of objects efficiently. We will need one orbit per each of our 12 target fields; target fields have been judiciously chosen to include multiple objects if possible. Our time estimate is based on our prior ACS imaging of I\, 20324 in the F606W and 814W filters. The IPHAS imaging (in a narrow-band H$\alpha$ filter, and broad-band $r{'}$, $i\prime$ filters) of these objects and I\, 20324 shows that they have roughly similar surface brightnesses to within a factor of 2; our selected targets are brighter than, or have comparable brightnesses to I\, 20324. The typical surface brightness for I\, 20324's tadpole body was about $3\times10^{-18}$ and $2.5\times10^{-18}$\, erg\, sec$^{-1}$\, cm$^{-2}$\, A$^{-1}$\, arcsec$^{-2}$ in the F606W and F814W filters, respectively. The total visual magnitudes of these structured, extended, faint objects are not useful for estimating exposure times and have all been set to a nominal value of 18 in the cover sheet. The stars seen in the head of I\, 20324 are of course much brighter than the nebulosity. We used pairs of dithered exposures, and achieved a S/N of about 10 in total exposure times of 11.5\, min for each filter. We will use a similar strategy for this proposal, except that we will add one short image in each of the broad-band filters for each target field, to correct for possible saturation effects towards the stellar sources in the tadpole heads. Conservatively assuming that the fraction of flux in the F606W filter due to line emission in H$\alpha$ and neighbouring [NII] lines is 0.5 (this fraction is likely to be higher from inspection of the emission line spectrum of I\, 20324 in Pereira \& Miranda 2007), we will use the remainder of the exposure time (about 15\, min) in the orbit for the F658N imaging, yielding a S/N ratio of $>$6. ------------------------------------------------------------------------------------ 15208( 3) -
