Astronomers have found a new way to measure the force of gravity on the surface of distant stars – GISMETEO.Novosti

The international team of astronomers from Austria, Germany, Canada, France and Australia has developed a technique for measuring the force of gravity on the surface of distant stars. It is to monitor the subtle variations in brightness of the stars. The findings of researchers published in the journal Science Advances .

If we know the surface gravity of the star, we can understand how much weight will the person on the star. For example, the Sun person would weigh 20 times more than on Earth, and a red giant (a future in store for our Sun) ?? 50 times less.

Since the surface gravity of the star depends on its mass and radius, the new technique will allow astronomers to more accurately measure the weight and size of distant stars. If these stars rotate around the planet, this information will help determine whether they exist conditions for life.

According to the professor of the University of British Columbia James Matthews, size exoplanets measured against the size of the star around which it revolves. The new technique will tell scientists how big and bright the star is and whether oceans exist on exoplanet water suitable for life.
