Massive Stars: From Birth to Death

Astrophysicist Dr Erin Higgins shares insights on the fascinating lives and deaths of massive stars, highlighting their significance in understanding the universe.

Dr Erin Higgins, an astrophysicist at the Armagh Observatory and Planetarium, specializes in researching the most massive stars in the universe and their evolutionary processes.

With a bachelor's degree in physics with astrophysics from Queen's University Belfast and a postgraduate certificate in education, Dr. Higgins brings a strong educational background to her research. She completed her PhD through a collaboration between Armagh Observatory and Planetarium and the Dublin Institute for Advanced Studies.

One aspect of her work involves collaborating with astronomers from the BRIDGCE UK Network to study the formation of essential elements in stars and how they are released through supernovae or powerful stellar winds.

In addition, Dr. Higgins is an advocate for gender equality in STEM subjects and serves as a representative for the Institute of Physics initiative known as Project Juno. Through this role, she contributes to education and outreach programs aimed at engaging the public and schools.

Delving into the Research of Massive Stars

Dr. Higgins' research focuses on unraveling the structure and evolution of stars through complex simulations. By examining their lives, physicists gain insights into the underlying physics that dictate their development and ultimate fates as either black holes or supernovae.

She has particularly explored theoretical models to study stars in the Magellanic Clouds, dwarf galaxies situated near our own Milky Way galaxy. By analyzing these observations, Dr. Higgins aims to gain a better understanding of nucleosynthesis, which pertains to the creation of elements in stars, and how they contribute to the chemical enrichment of our local environment.

While our sun plays a crucial role in sustaining life on Earth, it falls within the category of ordinary stars. Dr. Higgins emphasizes that the most massive stars discovered weigh up to 300 times the mass of our sun. These stars evolve differently from our sun despite originating from the same nebula.

Massive stars, due to their intense nuclear fusion reactions, produce the heaviest elements known. They also generate powerful stellar winds that eject billions of kilograms of material, leaving behind a core with only a fraction of the original star remaining. Ultimately, these massive stars climax in explosive supernovae, releasing energy that surpasses the brightness of an entire galaxy. The remnants left behind often manifest as black holes, while brand new elements are forged and dispersed throughout the surrounding space.

This continuous cycle of life and death among massive stars contributes to the enrichment of our universe, providing the essential ingredients for subsequent generations of stars and their accompanying systems. In fact, these stars are responsible for the creation of various elements found on Earth, including silicon for mobile phones, aluminium for cars, and gold for jewelry.

Dr. Higgins emphasizes the interconnectedness of the universe, illustrating that our sun and the elements comprising all life, such as carbon, iron, and calcium, originated from the cores of stars. Through her research, she aims to quantify the production and dispersion of different elements within stars, shedding light on this intricate cosmic process.

Unraveling Our Place in the Universe

Dr. Higgins's research serves as an important cornerstone for astronomy, offering insights into humanity's position in the vastness of space and our origin story. By fostering a global scientific community, researchers collaborate to address fundamental questions about our existence.

Her work not only encompasses the nature of massive stars and the creation of vital elements but also extends to exploring technological advancements in studying black holes.

Kindled Passion for Astrophysics

Dr. Higgins's fascination with astrophysics took root during her time at Thornhill College in Derry/Londonderry, where she participated in the astronomy club. Encouraged by her teachers and fueled by her passion, she pursued a career in astrophysics.

Her interest flourished as she engaged in evening observations of celestial objects through her 1-meter National Geographic telescope. Later, a work experience opportunity at Armagh Observatory solidified her decision to embark on a career in astrophysics.

Challenges and Misconceptions

Working in astrophysics presents unique challenges and misconceptions. The field demands flexibility due to the nature of the research, which often necessitates unconventional working hours and frequent travel. Moving to different countries every few years is a common occurrence.

Additionally, the pursuit of solving longstanding astronomical mysteries requires determination and perseverance.

Engagement with the Public

Dr. Higgins actively engages in public outreach, enlightening young audiences about the wonders of astronomy. Through numerous career events and virtual seminars, she has inspired students to pursue work experience and develop a keen interest in astronomy.
