Not Your Average Space Explosion: Very Long Baseline Array Finds Classical Novae Are Anything But Simple
Classical novae are one of the most common types of explosions in the universe. They occur when a white dwarf star pulls material from a companion star and ignites a thermonuclear explosion on its surface. These explosions are thought to be relatively simple, but new research using the Very Long Baseline Array (VLBA) has shown that classical novae are anything but simple.
What is the Very Long Baseline Array?
The VLBA is a network of ten radio telescopes spread across the United States, from Hawaii to the Virgin Islands. It is used to study a wide range of astronomical phenomena, from black holes to galaxies to the structure of our own Milky Way.
The Study
In a recent study published in The Astrophysical Journal Letters, researchers used the VLBA to study two classical novae: V1723 Aql and V959 Mon. They found that these explosions were much more complex than previously thought.
The Results
The researchers found that both V1723 Aql and V959 Mon had multiple emission components, indicating that they were not simple explosions. In addition, they found evidence of shock waves and magnetic fields in both novae.
Implications
These findings have important implications for our understanding of classical novae and their role in the universe. They suggest that these explosions are not as simple as previously thought and may play a more complex role in the evolution of stars and galaxies.
Conclusion
In conclusion, the VLBA has provided new insights into classical novae and their complexity. These findings have important implications for our understanding of the universe and its evolution. As we continue to explore the cosmos, it is clear that there is still much to learn about even the most common astronomical phenomena.
