Comments

GM Aurigae is a classical T Tauri star that has been studied at many wavelengths (optical through radio) with a variety of techniques (imaging, photometry, spectroscopy). The system is believed to be between 2 and 10 million years old and is surrounded by a large circumstellar dust disk. The dust disk is detected through the characteristic infrared excess emission in its broad band spectral energy distribution (SED) and has been imaged in scattered light by the Hubble Space Telescope. The disk is also seen in CO molecular line images where its velocity structure is well modeled with Keplerian rotation.
M Aur is a T Tauri type star with a circumstellar disk.
