Spectacular Stellar collisions won`t happen for billions of years from now

Washington: Astrophysicists from the Astronomical Observatory of the Faculty of Physics at University of Warsaw have found that Stellar collisions between the remains of monstrous stars will not occur until billions of years from now.

One might expect that collisions between the remains of monstrous stars , with masses reaching 200-300 times that of our Sun, would be among the most spectacular phenomena in the Universe. Perhaps they are, but we will unfortunately probably never have the chance to find out.

For a long time, astronomers have believed that the biggest stars in the Universe do not exceed 150 solar masses.

However, three years ago star clusters in the Magellanic Clouds were discovered to house "impossible" stars - tremendous monsters with masses between 200 and 300 times that of our own Sun.

The discovery aroused great interest among astrophysicists, in particular those involved in the century-long search for gravitational waves.

If such stellar monsters formed tight binary systems, collisions between their remnants could occur.

The gravitational waves resulting from such an event would be powerful enough that even our current detectors could sense them - and at distances much larger than for typical stellar black holes.

"But we cannot count on detecting any such spectacular collision," Dr. Krzysztof Belczynski of the Astronomical Observatory of the Faculty of Physics at the University of Warsaw, said.
