Aka proto-planetary disks.
Aka newborn solar systems.
What starts to happen after the death of a very dense star, is a supernova. A supernova is when the star explodes, what is released is a huge amount of dust and gas. Over hundreds of thousands of years very hot gas and dust starts to accumulate causing very intense winds and heat to collapse and expand. From this a gravitational force starts to act on the accumulating has and dust. From this it begins to rapidly rotate. Causing a spherical ball of gas to form, this is a newborn star. As this star collects more heat and gas it’s own gravitational force begins to act on the surrounding gas and dust.
It starts to attract an accumulation of dust and gas material which begin to form a disk around this newborn star, around this is a bubble-like shape of gas that work both as a protection of the newborn star and as a possible destruction to the star and it’s accretion disk.In my research in 2012, I was calculating the flux and luminosity of the stars to figure out how far the newborn star system has to be from the nearby massive star in order for the proplyd to not be affected by the ultraviolet radiation and stellar winds coming from the force of rotation from this nearby star. If these winds or radiation are too strong it can cause any type of accretion disk to get blown away, hence deterring any possible planets to form.
In NASA continuing this research, I am hopeful that one day one or a few proplyds can begin to form a solar system and possible planets that can be proper distance from its newborn star to develop an atmosphere and elements and possibly astrobiology!
