Z39481984

Z39481984 is a unique identifier assigned to a specific astronomical object, namely a star. This identifier is part of the SIMBAD astronomical database, which is maintained by the Centre de Données astronomiques de Strasbourg (CDS). The star in question is located in the constellation of Cygnus, also known as the Swan. It is classified as a variable star, specifically a Delta Scuti variable, which means its brightness fluctuates due to pulsations within the star.

The star's exact coordinates are right ascension 20 hours 36 minutes 54.7 seconds and declination +44 degrees 27 minutes 36.5 seconds. Its apparent magnitude, a measure of its brightness as seen from Earth, varies between 8.5 and 9.0. This variability is characteristic of Delta Scuti stars, which are known for their short-period pulsations.

Z39481984 is of interest to astronomers studying stellar evolution and the behavior of variable stars. Its classification and characteristics contribute to the broader understanding of stellar physics and the life cycles of stars. The SIMBAD database provides detailed information about this star, including its spectral type, which is A2, indicating a main-sequence star with a surface temperature around 8,500 Kelvin. This information is valuable for researchers and enthusiasts alike who are studying the cosmos.
