Two exoplanets were discovered in the orbit of their dead parents

Time stars consuming their fuel, they enter into a process of self-destruction, which varies according to the type of star.

Basically, the biggest stars are collapsing and annihilating due to gravity supernova explosions the release of large amounts of stellar matter into space, which acts as cosmic fertilizer for the formation of new stars.

When the rest of the stars use up their fuel, they first become very swollen and turn red giants then they collapse into stellar remnants called white dwarfs.

This will also be the fate of the Sun some five billion years from now, when scientists predict how its expansion phase will disappear or… turn all the inner planets of our solar system, namely Mercury, Venus, Earth, Mars, to coal. .

The most powerful space telescope ever created by man James Webbhe continues his stream of impressive discoveries almost daily two exoplanets each orbiting a white dwarf.

Apparently, both cases where there is a white dwarf exoplanet today had a planetary system at one time.

The two discovered planets appear to be far enough away from their parent stars to grow and survive the worst of it, although the conditions currently prevailing on the two planets would be extreme and certainly unfriendly to life.

“A small number of planets have been discovered around white dwarf stars.

“What is surprising about these two planets is that they are more similar to planets in the outer solar system in terms of temperature, age, mass and orbital characteristics than any other exoplanets identified to date.

“This is our first opportunity to see what a planetary system looks like after the death of a star,” he says Susan O Meulaly Astronomer of the Space Telescope Science Institute, head of the research team that made the discovery.

Two exoplanets WD 1202-232 and WD 2105-82 were observed directly by James Webb while orbiting white dwarfs.

A single exoplanet is located about 11.5 times the distance from the Earth to the Sun from its white dwarf host.

Another exoplanet now sits further away from its dead parent star, about 34.5 times the distance between our planet and the Sun.

The masses of the planets are currently uncertain, with researchers estimating them to be 1 to 7 times larger than our Solar System’s largest planet, Jupiter.

If the discovery is confirmed by further observations, there is no doubt that the study of these exoplanets will reveal to scientists many unknown facts about various types of cosmic processes and phenomena, about which we have little or even little knowledge.
