PDS5AB
PDS5AB is a binary star system located approximately 1,000 light-years away from Earth in the constellation of Cassiopeia. The system consists of two main components, PDS5A and PDS5B, which orbit each other with a period of about 1,000 years. PDS5A is a young, massive star with a spectral type of B2.5V, while PDS5B is a slightly less massive star with a spectral type of B3V. The two stars are separated by an average distance of about 100 astronomical units (AU), which is roughly the distance between the Sun and Pluto in our solar system.
The PDS5AB system is notable for its circumstellar disks, which are regions of gas and dust that
