A Spitzer IRAC Imaging Survey for T Dwarf Companions around M, L, and T Dwarfs: Observations, Results, and Monte Carlo Population Analyses
We report observational techniques, results, and Monte Carlo population analyses from a Spitzer Infrared Array Camera imaging survey for substellar companions to 117 nearby M, L, and T dwarf systems (median distance of 10 pc, mass range of 0.6 to ~0.05 M ). The two-epoch survey achieves typical dete...

Zusammenfassung: | We report observational techniques, results, and Monte Carlo population analyses from a Spitzer Infrared Array Camera imaging survey for substellar companions to 117 nearby M, L, and T dwarf systems (median distance of 10 pc, mass range of 0.6 to ~0.05 M ). The two-epoch survey achieves typical detection sensitivities to substellar companions of [4.5 Delta *mm] |
