We present a census of the population of deeply embedded young stellar objects (YSOs) in the Ophiuchus molecular cloud complex based on a combination of Spitzer Space Telescope mid-infrared data from...
Star Formation: Answering Fundamental Questions During the Spitzer Warm Mission Phase (2007)
Strom, Steve, Allen, Lori, Carpenter, John, Hartmann, Lee, Megeath, S. Thomas, Rebull, Luisa, ...
Through existing studies of star-forming regions, Spitzer has created rich databases which have already profoundly influenced our ability to understand the star and planet formation process on micro...
Spitzer: Accretion in Low-Mass Stars and Brown Dwarfs in the λ Orionis Cluster (2007)
Barrado Y Navascués , David, Stauffer, John R., Morales-Calderón, María, Bayo, Amelia, Fazzio, Giovanni, Megeath, Tom, ...
We present multiwavelength optical and IR photometry of 170 previously known low-mass stars and brown dwarfs of the 5 Myr Collinder 69 cluster (λ Orionis). The new photometry supports cluster...
