NGTS-1b, the "IMPOSSIBLE" planet that should not exist
NGTS - 1 b is a somewhat peculiar planet. Very massive, it orbit around a
little light dwarf star and it thus defies everything we know of astronomy. In
any case what said Daniel Bayliss, a researcher working for the University of
Warwick.
NGTS
- 1 b and its star are about six hundred light-years from our own planet, in
the constellation Dove.
NGTS-1b, an "impossible" and "unpublished" planet
As
a general rule, the planets form at the same time as their star. They are born
because of the gas and dust present in the disk surrounding the stars. The
process is of course an extremely long and planetary cores put about 100,000
years to form.
As
for the whole planet, it generally takes between ten and one hundred million
years to see emerge.
According
to the principles commonly accepted by astronomers, the size of a planet varies
depending on the star around which it orbit.
According
to theory, the small stars can so perfectly form Rocky planets of measured
size, but they have not enough material to form the gas giants the size of
Jupiter.
NGTS
- 1 b goes against this theory to his Immense part, she has indeed fall into
the category of the giant soft, but she orbiting a small star.
Because it size
Daniel
Bayliss and his team have made several observations based on the
Next-Generation Transit Survey (NGTS) and thus on the network of telescopes
installed in the Atacama Desert in Chile.
The
task was not easy however, because NGST-1b is very close to its star (about 3%
of the distance separating the Earth from the Sun), a small star with a fairly
low brightness.
Observing
the planet's system, they realized that its radius was equivalent to about 25%
of its star! History to put this figure in perspective, it must be remembered
that the radius of Jupiter represents for its part about 10% of the radius of
our own star.
This
discovery is extremely important, of course, and it should thus push the
astronomers to revise their models.
