NASA's Hubble Finds Sizzling Details About Young Star FU Orionis
2024年11月21日 · In 1936, young star FU Orionis (FU Ori) underwent a significant increase in brightness and has slowly declined in luminosity ever since. Once considered to be a stand-alone case, scientists have noted a small class of extremely tumultuous, young stars that experience large escalations in brightness, known as FU Ori objects.
NASA’s Hubble Finds Sizzling Details About Young Star FU Orionis
2024年11月21日 · In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our Sun. Unlike an exploding star though, it has declined in luminosity only languidly since then.

Hubble Telescope Finds Unexpectedly Hot Accretion Disk in FU Orionis
6 天之前 · First observed in 1936, FU Orionis became a hundred times brighter in months and has remained a unique object of study. Unlike typical T Tauri stars, its accretion disk touches the stellar surface due to instabilities. These are caused by the disk's large mass, interactions with companion stars, or material falling inwards.
A Star’s Unexpected Heatwave: FU Orionis Challenges
4 天之前 · This is an artist’s concept of the early stages of the young star FU Orionis (FU Ori) outburst, surrounded by a disk of material. A team of astronomers has used the Hubble Space Telescope’s ultraviolet capabilities to learn more about the interaction between FU Ori’s stellar surface and the accretion disk that has been dumping gas …

Disk Surrounding Star is Sizzling Hot - Astronomy
2024年11月21日 · New results from NASA's Hubble Space Telescope reveal that a young star, FU Orionis (FU Ori), is circled by a disk of material that is much hotter than expected—16,000 Kelvin, or nearly three times our Sun's surface temperature.
