0 Assigned ID: 3009 ----- Attempting Submission 1 (Fri Sep 28 13:27:05 GMT 2012) ----- Joint Spitzer/HST I have taken visits 14 and 15 off hold and included the relevant roll angle ranges for them. Please note that the faintness of this target (F125W = 23.5 mag) makes it one of the faintest Y dwarf candidates in the sky -- only WISE 1828+2650 with F125W = 24.1 is fainter. Because of the faintness we have converted visit 14 from a G102 grism observation into a second G141 grism observation to complement visit 15. Our reasoning is that we'd rather have one higher quality G141 spectrum that two spectra (G102 and G141) of lower quality. Also, may I ask why visits 05, 06, 11, and 12 are still listed as "Implementation"? These should be ready for scheduling, as are visits 14 and 15 included in this new re-submission. Thank you. 401027619 ----- Attempting Submission 1 (Thu Oct 04 20:02:34 GMT 2012) ----- ----- Attempting Submission 2 (Mon Nov 05 23:16:17 GMT 2012) ----- ----- Attempting Submission 3 (Tue Dec 18 20:29:55 GMT 2012) ----- ----- Attempting Submission 4 (Fri Jan 18 23:50:31 GMT 2013) ----- ----- Attempting Submission 5 (Tue Jan 29 23:54:26 GMT 2013) ----- ----- Attempting Submission 6 (Mon Mar 04 19:55:15 GMT 2013) ----- ----- Attempting Submission 7 (Thu Mar 21 18:35:30 GMT 2013) ----- ----- Attempting Submission 8 (Wed Mar 27 21:07:11 GMT 2013) ----- ----- Attempting Submission 9 (Fri May 31 21:23:23 GMT 2013) ----- Spitzer Trigonometric Parallaxes of the Solar Neighborhood's Coldest Brown Dwarfs There are rare times in astronomy when -- by fortuitous circumstances, careful planning, or both -- giant leaps forward in our understanding can be made within a very short time. The combination of WISE, Spitzer, and HST is now capable of fast forwarding our knowledge of the immediate Solar Neighborhood. With just six months of survey operations, WISE was able to give us an unprecedented view of the entire sky that revealed the positions of the coldest brown dwarfs with effective temperatures as cold as ~300K (i.e., room temperature). With the investment of two years of Spitzer follow-up, we are capable of having distances measured for all of them. In this proposal, we consider a volume-limited (d < 20 pc) sample of the coldest known spectral types, T6 through early Y. These are the objects that give us the most leverage in discerning the shape of the low-mass end of the field mass function as well as defining the low-mass cutoff itself. Although ongoing ground-based programs will provide astrometric monitoring of about half of the sample, Spitzer Cycle 9+10 is needed to measure trigonometric parallaxes for the other half (79 objects), which include the faintest and coldest objects and hence those most difficult to monitor. A combination of current ground-based and HST Cycle 20 spectroscopy will complete the picture by providing the spectral classfications needed for temperature determination on this sample. Having distances and temperature determinations for all of the coldest objects in the the Sun's environs allows us an unprecedented look at the modern-day products of past star formation and our most comprehensive, three-dimensional view to date of the Solar Neighborhood. We will acquire G102 and G141 grism spectroscopy to determine accurate classifications (and hence temperatures) across the 0.8 - 1.7 micron region. To provide a wavelength calibration and registration for the slitless grism images, direct images of the fields in the F125W (for G141) and F098M (for G102) filters will have to be acquired. Because the WFC3 grism observations are slitless, roll angle constraints must be placed on the observations in order to avoid contamination of the target by other sources in the field. To eliminate any possibility of contamination, we will first observe each candidate through the F125W filter alone so that we can use the resulting images and the aXeSIM software to derive precise, contamination-free roll angles which will then be entered in to the APT for subsequent grism imaging.
