What's Happening?
Leslie Peltier, renowned as one of the world's greatest amateur astronomers, made significant contributions to the field by discovering numerous comets and recording over 132,000 variable star observations. His autobiography, 'Starlight Nights,' recounts his passion for astronomy and his observations through a 12-inch refractor telescope. A particular observation described in his book involved two pulsating stars in Cassiopeia, referred to as 'two tiny diamonds.' Amateur astronomer Doug Zubenel, inspired by Peltier's work, embarked on a quest to identify these stars. By examining Peltier's digitized variable star observations, Zubenel identified CE Cas A and CE Cas B as the likely candidates. These stars are classical pulsating Cepheid variables located in the open cluster NGC 7790, visible in the fall, matching the timeframe of Peltier's observations.
Why It's Important?
The identification of Peltier's 'two tiny diamonds' highlights the enduring impact of amateur astronomers on the field of astronomy. Peltier's meticulous observations have inspired generations of astronomers, demonstrating the value of amateur contributions to scientific discovery. Zubenel's detective work underscores the importance of preserving and analyzing historical astronomical data, which can lead to new insights and confirmations of past observations. This discovery also emphasizes the collaborative nature of astronomy, where enthusiasts and professionals alike contribute to the understanding of celestial phenomena. The story of Peltier and Zubenel serves as a testament to the passion and dedication that drives scientific inquiry, encouraging others to explore the night sky and contribute to the collective knowledge of the universe.
What's Next?
While the identification of Peltier's 'two tiny diamonds' provides closure to a long-standing mystery, it opens up opportunities for further exploration of variable stars and their characteristics. Amateur astronomers may be inspired to delve into historical data to uncover other unidentified observations, potentially leading to new discoveries. The story may also encourage the digitization and analysis of more historical astronomical records, preserving the legacy of past astronomers and facilitating future research. Additionally, the identification of CE Cas A and CE Cas B as pulsating Cepheid variables may prompt further study of these stars and their role in understanding stellar evolution and distance measurement in the universe.
