Deep JHKs and Spitzer Imaging of Four Isolated Molecular Cloud Cores (2009)

Chapman, Nicholas L., Mundy, Lee G.

We present observations in eight wavebands from 1.25-24 microns of four dense cores: L204C-2, L1152, L1155C-2, and L1228. Our goals are to study the YSO population of these cores and to measure the...

Primordial circumstellar disks in binary systems: evidence for reduced lifetimes (2009)

Cieza, Lucas A., Padgett, Deborah L., Allen, Lori E., McCabe, Caer E., Brooke, Timothy Y., Carey, Sean J., ...

We combine the results from several multiplicity surveys of pre-main-sequence stars located in four nearby star-forming regions with Spitzer data from three different Legacy Projects. This allows us...

The Mid-Infrared Extinction Law in the Ophiuchus, Perseus, and Serpens Molecular Clouds (2008)

Chapman, Nicholas L., Mundy, Lee G., Lai, Shih-Ping, Evans II, Neal J.

We compute the mid-infrared extinction law from 3.6-24 microns in three molecular clouds: Ophiuchus, Perseus, and Serpens, by combining data from the "Cores to Disks" Spitzer Legacy Science program...

The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds: VII. Ophiuchus Observed with MIPS (2007)

Padgett, Deborah L., Rebull, Luisa M., Stapelfeldt, Karl R., Chapman, Nicholas L., Lai, Shih-Ping, Mundy, Lee G., ...

We present maps of 14.4 deg^2 of the Ophiuchus dark clouds observed by the Spitzer Space Telescope Multiband Imaging Photometer for Spitzer (MIPS). These high quality maps depict both numerous point...

The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds. IV. Lupus Observed with MIPS (2007)

Chapman, Nicholas L., Lai, Shih-Ping, Mundy, Lee G., Brooke, Timothy Y., Cieza, Lucas A., ...

We present maps of 7.78 deg^2 of the Lupus molecular cloud complex at 24, 70, and 160 μm. They were made with the Spitzer Space Telescope Multiband Imaging Photometer for Spitzer (MIPS) instrument...

Chapman, Nicholas L., Lai, Shih-Ping, Mundy, Lee G., Evans II, Neal J., Brooke, Timothy Y., Cieza, Lucas A., ...

We present maps of 7.78 square degrees of the Lupus molecular cloud complex at 24, 70, and $160\:\mu$m. They were made with the Spitzer Space Telescope's Multiband Imaging Photometer for Spitzer...
