Abstract

Planetary camera images of HL Tauri have been obtained through V-, R-, and I-band niters using the Wide Field and Planetary Camera 2 aboard the refurbished Hubble Space Telescope. These images show that HL Tairi is entirely reflection nebulosity at optical wavelengths, with no optical star visible to a limiting magnitude of V = 25.5. The optical nebula extends northeast of the stellar position along the direction of HL Tau's optical jet and has an unusual C-shaped morphology. The bright core of the nebula is only 1″ in size and is centered only 1″.2 from the actual stellar position. We estimate that visual extinction toward the unseen point source is at least 22 mag and that the stellar phot..
