Taurus-2: Finishing the Spitzer Map of the Taurus Molecular Clouds

Taurus-2 Research Project Operational


Taurus-2 is a comprehensive, unbiased and spatially contiguous map of the Taurus Molecular Clouds (TMC) using Spitzer's MIPS and IRAC instruments. Taurus-2 adds an area of 24 square degrees to previous Spitzer observations of the TMC and restores  full coverage of L1495 and L1536.

Achieving sensitivities 20 times better than ISOCAM at 8 microns, and 200 times better than IRAS at 24 microns, these maps reveal the lowest luminosity members of the young stellar population in western Taurus: collapsing protostars, young substellar objects, and edge-on disks.

This survey is a central and crucial part of a multiwavelength study of the Taurus cloud complex performed using XMM and CFHT. The seven photometry data points obtained from Spitzer allows characterization of the circumstellar environment of each object, and, in conjunction with NIR photometry, construction of a complete luminosity function for the cloud members to place constraints on the initial mass function. 

Taurus-2 was selected as a Spitzer Legacy Project in cycle 3.

IPAC's role:

The Taurus-2 PI is IPAC scientist Deborah Padgett. The Taurus-2 team includes past and present IPAC scientists including Tim Brooke, Sean Carey, Bill Latter, Alberto Noreiga-Crespo, Luisa Rebull and David Shupe.

MIPSGAL data is hosted by IRSA at IPAC, including the raw observations from Spitzer in the Spitzer Heritage Archive, and enhanced data products and tools.
