HL Tauri (abbreviated HL Tau) is a young T Tauri star [5] in the constellation Taurus, approximately 450 light-years (140 pc) from Earth [1] in the Taurus Molecular Cloud. [6] The luminosity and effective temperature of HL Tauri imply that its age is less than 100,000 years. [7] At apparent magnitude 15.1, [3] it is too faint to be seen with ...

2024年2月29日 · HL Tauri’s protoplanetary disk is unusually massive and bright, which makes it an excellent place to search for signs of forming planets. The new ALMA observations revealed at least three times as much water as in all of Earth’s oceans in the inner part of the disk.

2014年11月6日 · Astronomers using the Atacama Large Millimeter/submillimeter Array captured an image of a protoplanetary disk around a Sun-like star known as HL Tauri.

2023年11月15日 · One of the first high resolution images that ALMA captured was of HL Tauri, a young star just 480 light-years away surrounded by a protoplanetary disk. The disk has visible gaps which could be where young protoplanets are forming.

2014年11月6日 · For ALMA’s first observations in its new and most powerful mode, researchers pointed the antennas at HL Tauri — a young star, about 450 light-years away, which is surrounded by a dusty disc [1]. The resulting image exceeds all expectations and reveals unexpectedly fine detail in the disc of material left over from star birth.

2023年11月21日 · Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have captured a high-resolution image of HL Tauri, a young star in the constellation of Taurus. Rings of dust surrounding HL Tauri, with line patterns showing the orientation of polarized light.

2014年11月6日 · This revolutionary new image reveals in astonishing detail the planet-forming disk surrounding HL Tau, a Sun-like star located approximately 450 light-years from Earth in the constellation Taurus. ALMA uncovered never-before-seen features in this system, including multiple concentric rings separated by clearly defined gaps.

2024年4月15日 · New features detected by Webb are superimposed in orange on HL Tauri and its protoplanetary disk, located 357 light-years from Earth. The image reveals material in the envelope immediately...

2024年9月30日 · Scientists have discovered a massive cloud of water vapor around the young star HL Tauri, about 450 light-years away. The vapor, which is three times the volume of Earth's oceans, may play a key role in planet formation and offers a …

2024年2月29日 · The observations reveal at least three times as much water as in all of Earth’s oceans in the inner disc of the young Sun-like star HL Tauri, located 450 light-years away from Earth in the constellation Taurus.
