T Tauri
Abstract
M. Karovska, P. Nisenson, R. Noyes, C. Papaliolios and R. Stachnik, Center for Astrophysics, write: "Speckle image reconstructions of T Tau show a second, unresolved source located ~ 0"35 from T Tau at p.a. ~ 5 deg. The source was first detected at the Steward Observatory's 2.3-m telescope in 1983 Nov., and it was detected again using the 2.5-m telescope at Mt. Wilson Observatory in 1984 Nov., thus confirming its reality. Both sets of data were obtained through broad-band filters centered near 660 nm (and including H=alpha), using a two-dimensional photon-counting PAPA detector. The source appears to be ~ 4 mag fainter than T Tau itself in this wavelength band. We note that this appears to be a third component of the T Tau system; it is not the object reported by infrared and radio observers as being south of T Tau. Further optical or infrared observations of T Tau during the remainder of this observing season would be most useful."
