WebMost of the material along the lengths of the pillars has been stripped away, but the caps still contain pockets of denser gas and dust. As the radiation from the ionising stars reaches the tops of the pillars, the gas is boiled away in a process known as photoevaporation, leaving visible streamers twisting out from the surface of the pillar caps. Webphotoevaporation desert. Here we report the first mass and density measurements of a planet in the photoevaporation desert, as well as the mass and density of a USP planet in a multiplanet system. K2-66 (EPIC206153219) is a G1 subgiant star in K2 Campaign 3 (C3), which hosts a transiting sub-Neptune in the photoevaporation desert.

WebMay 1, 2015 · The structure and evolution of protoplanetary disks, especially the radial flows of gas through them, are sensitive to a number of factors. One that has been considered only occasionally in the literature is external photoevaporation by far-ultraviolet (FUV) radiation from nearby, massive stars, despite the fact that nearly half of disks will experience … WebI am a sixth-year graduate student working with Professor Dong Lai on the dynamics of exoplanets and stellar binaries/triples. A major subject of my research is the formation of short-period planets and binaries via "high-eccentricity migration," in which a planet or stellar binary with an initially large separation is perturbed into a highly eccentric orbit, with … howard lotor

WebIn our Galaxy, star formation occurs in a variety of environments, with a large fraction of stars formed in clusters hosting massive stars. OB stars have an important feedback on the evolution of protoplanetary disks o… WebThe photoevaporation region is constructed by using the fact that the photoevaporation profile is self-similar when the radius is scaled in terms of R g (i.e. if the gap opens at 1 au … WebAug 23, 2004 · We have now performed a larger set of high-resolution simulations to determine and quantify the dependence of minihalo photoevaporation times and photon … howard loud house
