Astronomer Prof Simon Jeffery has dedicated his career to exploring rare old stars and unraveling their significance in the grand tapestry of our universe. From his early days at the Royal Observatory in Edinburgh to his current role as a senior research astronomer at Armagh Observatory and Planetarium, Jeffery has been a key player in the field of hot subdwarf stars for over two decades.
A Busy Month for Armagh Observatory and Planetarium
In September, the Armagh Observatory and Planetarium hosted several notable events in the field of astronomy. The annual British Association of Planetaria took place on the 1st and 2nd of the month, followed by an international workshop on AM CVn binaries from the 5th to 8th September. The most recent event was the 11th international conference on Hot Subdwarf Stars and Related Objects, organized by Prof Simon Jeffery and his team.

Jeffery's research focuses on stars that are nearing the end of their lives, undergoing mergers or internal explosions that rejuvenate them. These stars lack hydrogen on their surfaces and are instead rich in helium, making them exceptionally rare. To discover new types of helium stars, Jeffery has led a groundbreaking project utilizing the Southern African Large Telescope (SALT). The project has already observed hundreds of stars and aims to reach almost 800 stars by the end of 2024, uncovering new insights into the complexities of stellar evolution.
The Significance of Jeffery's Research
Understanding the workings of the universe is at the heart of astronomy, and stars play a crucial role in this exploration. Stars facilitate the conversion of hydrogen and helium into heavier elements, shaping the evolution of new star and planet systems. As stars approach the end of their lives, their paths become increasingly intricate, often involving interactions with other stars. Jeffery's research fills in the gaps and connects the dots, providing valuable insights into the bigger cosmic picture.

Jeffery's passion for astronomy was ignited at a young age, fueled by his natural curiosity and encouragement from his grandmothers, who were teachers. As a child, he devoured articles about stellar evolution and was fascinated by the mysteries of the cosmos. His journey into astronomy took off during his gap year when he worked at the Royal Observatory in Edinburgh and discovered his calling in the study of stellar evolution.
Challenges and the Joy of Scientific Exploration
While Jeffery considers himself fortunate to have pursued a fulfilling career in astronomy, he acknowledges the challenges faced by early-career scientists, including job insecurity and the difficult balancing act of family life. Communicating the technical nature of his work is another hurdle, as the intricacies of observation, data analysis, and model building can be challenging to explain to the general public. However, he remains passionate about sharing the wonders of science and astronomy, especially through the efforts of the Armagh Observatory and Planetarium in engaging the public and inspiring future STEM leaders.
