Sentences with word «photoevaporation»

The team analysed the effect of this energetic radiation on the pillars: a process known as photoevaporation, when gas is ionised and then disperses away.
By observing the results of photoevaporation — which included the loss of mass from the pillars — they were able to deduce the culprits.
Some researchers have proposed that this difference is caused by photoevaporation, which strips planets of their surrounding envelope of so - called volatiles — substances like water and carbon dioxide that have low boiling points — creating smaller - radius planets.
The team used several hundred thousand compute hours at NERSC to produce a series of 2D and 3D simulations that helped them examine the role of dark matter halo photoevaporation — where energetic radiation ionizes gas and causes it to disperse away from the halo — played not just in the early formation of stars but also the assembly of later galaxies.
I am particularly interested in environmental effects on star and planet formation, such as in high mass star forming regions, where external photoevaporation may play an important role on disk evolution and planet formation.
Previous simulations have already sparked assumptions from scientists regarding the possibility that the atmosphere of hot super-Earths are being stripped off through photoevaporation.
B) How much mass is lost via central star - driven photoevaporation?
The fraction of observed passive disks and the observed spectral type dependence can both be explained by models of disk evolution that include disk photoevaporation from the central star.
«But as ALMA can image the material in the entire disc in much greater detail than other facilities, we could rule out the alternative photoevaporation scenario.
This in turn has allowed them to choose between the two options — photoevaporation or young planets — as the cause of the gaps for the first time.
Notes [1] This process, which clears the dust and gas from the inside out, is known as photoevaporation.
