WebOnce these planetary bodies acquire enough mass, they dramatically reshape the structure of the disk, fashioning rings and gaps as the planets sweep their orbits clear of debris and shepherd dust and gas into tighter and more confined zones. In the visible, HL Tauri is partly obscured by the massive cloud of dust and gas that surrounds it. HL Tauri (abbreviated HL Tau) is a very young T Tauri star in the constellation Taurus, approximately 450 light-years (140 pc) from Earth in the Taurus Molecular Cloud. The luminosity and effective temperature of HL Tauri imply that its age is less than 100,000 years. At apparent magnitude 15.1, it is too faint to … See more Indications of a protoplanetary disk were first presented in 1975 with infrared spectral observations in wavelengths between 2 and 4 microns, which were made possible by the recent invention of the indium antimonide photovoltaic … See more • Media related to HL Tauri at Wikimedia Commons See more • A wider view of the region from the Hubble Space Telescope in visible light shows the Herbig–Haro object HH 150. • A broader view of the Taurus … See more
WebHL Tauri (abbreviated HL Tau) is a very young T Tauri star in the constellation Taurus, approximately 450 light-years (140 pc) from Earth in the Taurus Molecular Cloud.
