On the nature of the candidate T-Tauri star V501 Aurigae
Monthly Notices of the Royal Astronomical Society(2017)
摘要
We report new multicolour photometry and high-resolution spectroscopic observations of the long-period variable V501 Aur, previously considered to be a weak-lined T-Tauri star belonging to the Taurus–Auriga star-forming region. The spectroscopic observations reveal that V501 Aur is a single-lined spectroscopic binary system with a 68.8-d orbital period, a slightly eccentric orbit (e ∼ 0.03), and a...
