Ultraviolet “winds” from nearby massive stars are stripping the gas from a young star’s protoplanetary disk, causing it to rapidly lose mass, according to a new study. It reports the first ...
Some of the disk falls onto the star and some is heated up by X-ray and ultraviolet radiation from the star and evaporates in a wind. ... known as "photoevaporation," usually takes between 5 and ...
The presence of this MHD wind has implications for the disk dispersal process and poses questions about the role of photoevaporation in disk dispersal. See Fang et al. Image: Dawei Li (Xiamen ...
The dusty disk surrounding the star TW Hydrae exhibits circular features that may signal the formation of protoplanets. ... the team attributes the feature to a process known as photoevaporation.
The dusty disk that girdles TW Hydrae has long been a favored object of observation. The star lies only 175 light-years from Earth, and is it relatively young (around 106 years old).
The first step in tackling disk-wind movements is simply to find a disk-wind subject. And to find a disk-wind subject, you need to find a protoplanetary disk, of course.
The disk is surrounded by higher-massed stars, around 10 times the mass of the Sun. Astronomers have detailed their observations in a new study published by Science.
Using NASA's Chandra spacecraft, astronomers have found "danger zones" for worlds where planet-birthing disks are blasted with high-energy radiation from massive young stars and rapidly disintegrate.
Photoevaporation phenomenon. For d203-506, this dazzling neighborhood is not without consequences, as it emits highly energetic ultraviolet ... In other words, the protoplanetary disk loses its gas.
Some of the disk falls onto the star and some is heated up by X-ray and ultraviolet radiation from the star and evaporates in a wind. ... known as "photoevaporation," usually takes between 5 and ...
