Title: Near Infrared Spectroscopy of the Unique T Tauri Binary System KH 15D
Abstract:
We propose to obtain medium resolution Gemini/NIRI J-band spectra of the
unique T Tauri binary system KH 15D at two orbital phases to search for and
characterize a putative third body. The data will also permit us to assess
the spectral differences between stars A and B and to extend the search for a
reflectance spectrum signature of silicate minerals and/or ice. KH 15D is the
only known example of a system at the key phase of planet formation where a
settled particulate layer of chondrule (mm) sized objects has clearly formed,
but planetesimal formation has not yet occurred. As such, it deserves
intensive study to ascertain its structure in detail and the possibility that
there is third light in the system requires the close scrutiny that is only
possible with an 8-10m class telescope.
