Trappist-1 Water and Life Possibilities

The Trappist-1 System
Trappist-1, a star about 40 light years from Earth, is a cryogenic dwarf star with a mass only 0.08 times that of the Sun (80 times that of Jupiter) and a radius 1.12 times that of Jupiter.

Planet Trappist-1
Liege, Belgium The Institute of Astrophysics at the University of Liege, Belgium
Dr. Michael Giron
is the scientist who discovered the first planet in the Trappist-1 system.
The method used to discover planets in the Trappist-1 system is the transit method.
The transit method is based on observing the fading of a planet in front of a star as it orbits the star. The famous Kepler space telescope also uses the transit method.
Dr. Giron, who discovered the transit method, also used the transit method.
Dr. Giron, who discovered the planet using the transit method, said, "So many planets were in transit that we didn't know how many planets there were.

Planets in the Trappist-1 system
A planet in the Trappist-1 system discovered by the transit method. Since there are seven planets in the Trappist-1 system, they are affectionately known as the "Seven Sisters.
Even if a planet undergoes a transit, its period changes slightly due to the gravity of other planets. By observing this, the mass of the planet is calculated. In doing so, it turns out to be the size of the Earth, along with its radius and mass. Since there are seven of them, they are said to be the new home of life. The planets that are in the habitable zone are Trappist-1e Trappist-1f
Trappist-1g. These planets and Trappist-1h outside of them may have large amounts of water because their density is so much smaller than that of the Earth. This makes them so-called "waterworlds," planets whose surfaces are entirely composed of oceans. However, since it is so close to the star, it is tidally locked, and the area where water exists may be limited to the surface that hits the star and the surface where ocean currents flow. But if it contains salt, water could exist throughout the planet. As such, life would be highly likely. The effects of the Trappist-1 flare would not be a problem if deep underground. Based on this, life would be highly probable.

I will finally be able to add exoplanets in WinStars 3. I might need your help. See you soon!
