[14.18] Observations of Young Stellar Objects with the Palomar Testbed Interferometer and the Keck Interferometer

R.L. Akeson (MSC, Caltech)

Infrared interferometry observations of T Tauri stars are presented from the Palomar Testbed Interferometer and the Keck Interferometer. The objects span a range of both stellar properties (spectral types from K7 to G2) and disk properites (accretion rates from 1 x 10-9 to 2 x 10-7 solar mass/year and infrared excesses from 10 to 80%). In most cases, the sources are resolved and we derive characteristic sizes assuming simple source morphologies. Assuming the resolved emission represents the inner edge of the dust disk, we compare the measured sizes to the predicted dust sublimation radius. The Keck Interferometer is a NASA-funded project.
