The Dust Emissivity Spectral Index in the Starless Core TMC-1C (2009)

Schnee, Scott, Enoch, Melissa, Noriega-Crespo, Alberto, Sayers, Jack, Terebey, Susan, Caselli, Paola, ...

In this paper we present a dust emission map of the starless core TMC-1C taken at 2100 microns. Along with maps at 160, 450, 850 and 1200 microns, we study the dust emissivity spectral index from the...

The Gas Temperature of Starless Cores in Perseus (2008)

Schnee, Scott, Rosolowsky, Erik, Foster, Jonathan, Enoch, Melissa, Sargent, Anneila

In this paper we study the determinants of starless core temperatures in the Perseus molecular cloud. We use NH3 (1,1) and (2,2) observations to derive core temperatures (T_kin) and data from the...

Infrared and Millimetric Study of the Young Outflow Cepheus E (2008)

Alberto Noriega-crespo, Sergio Molinari, Leonardo Testi, Anneila Sargent

The Cepheus E outflow has been studied in the mid and far infrared using the ISO CAM and LWS instruments, and at millimetric wavelengths using OVRO. In the near and mid-IR, its morphology is similar...

The Spitzer c2d Survey of Weak-line T Tauri Stars II: New Constraints on the Timescale for Planet Building (2007)

Cieza, Lucas, Padgett, Deborah L., Stapelfeldt, Karl R., Augereau, Jean-Charles, Harvey, Paul, Evans, Neal J., ...

One of the central goals of the Spitzer Legacy Project ``From Molecular Cores to Planet-forming Disks'' (c2d) is to determine the frequency of remnant circumstellar disks around weak-line T Tauri...

AB Aurigae Resolved: Evidence for Spiral Structure (2005)

Corder, Stuartt, Eisner, Josh, Sargent, Anneila

We obtained high angular resolution (~2") images of the 13CO(J=1-0) line and 2.7 millimeter continuum emission, and slightly lower resolution images of 12CO(J=1-0) and C18O(J=1-0) line emission...

Star formation in clusters: a survey of compact mm-wave sources in the Serpens core (1998)

Testi, Leonardo, Sargent, Anneila

We report the results of a millimeter interferometric survey of compact 3 mm continuum sources in the inner 5.5'x5.5' region of the Serpens core. We detect 32 discrete sources above 4.0 mJy/beam, 21...

Disk Mass Limits and Lifetimes of Externally Illuminated Young Stellar Objects Embedded in the Orion Nebula

John Bally, Leonardo Testi, Anneila Sargent, John Carlstrom

We present 1.3 millimeter wavelength interferometric observations of two fields containing 6 externally illuminated young stellar objects embedded within the Orion Nebula that have been observed with...
