With Herschel/PACS 134 low mass members of the Taurus star-forming regionspanning the M4-L0 spectral type range and covering the transition from lowmass stars to brown dwarfs were observed. Combining the new Herschel resultswith other programs, a total of 150 of the 154 M4-L0 Taurus members membershave observations with Herschel. Among the 150 targets, 70um flux densitieswere measured for 7 of the 7 ClassI objects, 48 of the 67 ClassII members, and3 of the 76 ClassIII targets. For the detected ClassII objects, the median 70umflux density level declines with spectral type, however, the distribution ofexcess relative to central object flux density does not change across thestellar/substellar boundary in the M4-L0 range. Connecting the 70um TBOSSvalues with the results from K0-M3 ClassII members results in the firstcomprehensive census of far-IR emission across the full mass spectrum of thestellar and substellar population of a star-forming region, and the median fluxdensity declines with spectral type in a trend analogous to the flux densitydecline expected for the central objects. SEDs were constructed for all TBOSStargets covering the optical to far-IR range and extending to the submm/mm fora subset of sources. Based on an initial exploration of the impact of differentphysical parameters; inclination, scale height and flaring have the largestinfluence on the PACS flux densities. From the 24um to 70um spectral index ofthe SEDs, 5 new candidate transition disks were identified. The steep 24um to70um slope for a subset of 8 TBOSS targets may be an indication of truncateddisks in these systems.Two examples of mixed pair systems that includesecondaries with disks were measured. Finally, comparing the TBOSS results witha Herschel study of Ophiuchus brown dwarfs reveals a lower fraction of disksaround the Taurus substellar population.
