XZ Tau and HL Tau monitoring needed for Chandra observations
Abstract:
Dr. David Principe (MIT) has requested AAVSO observers' assistance in monitoring the classical T Tauri star binary XZ Tau in support of Chandra observations scheduled between tonight and November 15. Coverage of the very nearby HL Tau, a classical T Tauri star, is also requested but at a lower priority.
Justification:
The purpose of the Chandra observations are to identify signatures of accretion shocks on the surface of the star and thus determining its outburst state with optical photometry is helpful.
Requested Data Types:
