389467

389467 is a cataclysmic variable star located in the constellation Boötes. It is a dwarf nova, which is a type of cataclysmic variable that undergoes periodic explosions. These explosions, known as outbursts, are caused by the accumulation of material on the surface of the white dwarf companion star.

The star is named after its J2000.0 coordinates, which designate its position in the sky. 389467 is classified as a Z Camelopardalis type variable, which means that its outbursts are of the "standstill" type, where the amplitude of the outbursts remains constant over time.

The outbursts of 389467 have been observed to have a periodicity of approximately 57 days, with some variability in the exact timing between outbursts. This periodicity is likely due to the gravitational interaction between the white dwarf and the companion star in a close binary system.

Studying 389467 provides valuable insights into the physics of cataclysmic variables and the behavior of binary star systems. Research on this star can also contribute to our understanding of the properties of white dwarf stars and their role in the binary systems they inhabit.

Observations of 389467 have been conducted using a variety of astronomical instruments, including telescopes and spectrographs. The data collected from these observations has been used to derive the star's light curve and properties, which can be used to compare with theoretical models and simulate binary star systems. Further research on 389467 is necessary to fully understand its properties and behavior.
