What are the most common eclipsing binary stars and variable stars to observe with periods of a few hours?
Im observing from Ireland.
Thanks
In eclipsing binary systems, variables are stars that appear to change in brightness due to their orbiting companion star passing in front of them. This causes a periodic dimming of the variable star's light, which can be measured and studied.
Eclipsing binary systems are formed when two stars are in a close orbit around each other, with their orbital plane aligned with our line of sight. This allows for one star to periodically pass in front of the other, creating the observed changes in brightness.
By studying eclipsing binary systems, scientists can determine the sizes, masses, and temperatures of the stars involved. This can also provide insights into the evolution and lifecycles of stars.
Eclipsing binary systems can be used as standard candles to measure distances in the universe. By comparing the observed brightness of these systems to their known properties, scientists can calculate their distance and use this information to measure distances to other objects in the universe.
Eclipsing binary systems are not rare, as they are estimated to make up about 40% of all known binary star systems. However, they may be more difficult to detect and study due to their periodic and often subtle changes in brightness.
