Are there any known examples of colliding stars? has the phenomena ever been observed?

Vanadium 50 said:You also have a phenomenon call "blue stragglers" in clusters.
Note that "collision" is really only a special case of "mass transfer", which we see all the time.
stargazer3 said:Gamma-ray bursts, a great high-energy flashes observed every day in the sky, are thought to be the pruducts of collision between two neutron stars. It is not a head-on collision (due to a very low probability of such an interaction), but it is a hot topic in astrophysics now.
Here's a great introductory video about it. Not very relevant to head-on stuff, but hey, we all love big explosions, right?
Edit: LVP_man, there are simulations in that link, and I'd guess the stars are of equal mass.
The purpose of searching for colliding stars is to gain a better understanding of the evolution and dynamics of stars. Collisions between stars are rare and short-lived events, but they can provide valuable insights into the formation and behavior of stars.
Scientists use various methods to search for colliding stars, such as observing changes in the light emitted by stars, detecting gravitational waves, and analyzing data from telescopes and satellites.
Yes, the phenomena of colliding stars have been observed several times. In 2017, the first-ever observed collision between two neutron stars was detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo interferometer. This event, known as GW170817, also provided evidence for the production of gold and other heavy elements in such collisions.
Observing colliding stars can help scientists to test and refine theories about the formation and evolution of stars. It can also provide insights into the production of heavy elements, the behavior of matter under extreme conditions, and the nature of gravity.
Studying colliding stars can have a wide range of potential future implications, including advancements in our understanding of the universe, the development of new technologies, and the discovery of new phenomena. It can also have practical applications, such as improving our ability to predict and prepare for potential hazards from cosmic collisions.
