PLANETS WITH TWO SUNS MAY INCREASE THE CHANCE TO HAVE LIFE

                                  Planets with two suns should be more capable of supporting life than other planets. These type of having dual suns might actually help prevent the damaging solar winds from bombarding planets in their system. Joni Clark, a undergraduate student at new mexico state university said, " It's like a really good marriage. they vent to each other, and they're not focused on anything else. They slow each other down and that causes increased magnetic  protection of the planets."
                                 When the stars in a binary are somewhat evenly matched in mass, the can enter into a synchronized dance that keeps solar winds to a minimum. The stars also need to fully orbit one another within 10 to 30 days to expand the habitable zone. If they drift too far apart, it could put a significant gravitational strain on the orbiting planets.
                                 The magnetic fields of the planets aren't necessarily boosted in these kinds of binary system, Clark said, but they don't have to deal with as much solar wind assault. Waterly worlds and rocky planets could form in areas of the system that might not be habitable without the double star interaction, he added.
                                  Clark said, " It also leaves the potential open for smaller planets that have less magnetic field protection to remain habitable as they don't have to protect themselves from as much as they would in a single star case." he found that p- type planets received 0.7 % less flux from solar wind than earth depending on their position in the solar system. Potentially, p-type binaries could have more potential for habitability." In these system, it's also possible that habitable alien planets could exist as close-in to their stars as Venus is to the sun.
