A theoretical lab that unravels the mysteries of supernovae and black holes.
AboutAbout the lab
Theoretical astrophysics probing how stars end their lives
The Yamada Lab theoretically studies what happens at the end of a star's life.
The lab investigates the mechanism of gravitational collapse, in which the core of a star far more massive than the Sun collapses under its own gravity at the end of its evolution.
Using models and simulations, the lab studies the resulting supernova explosions and the formation of neutron stars and black holes.
The lab also works on high-energy phenomena in the universe, such as gamma-ray bursts and magnetars, which are neutron stars with extremely strong magnetic fields.
Key terms
- Gravitational collapse
- A phenomenon in which a star can no longer support its own weight and its core collapses rapidly
- Neutron star
- An extremely dense object formed after a star undergoes gravitational collapse
- Magnetar
- A special type of neutron star with an extremely strong magnetic field

The lab theoretically studies the process that begins with gravitational collapse, which occurs at the end of the evolution of stars far more massive than the Sun, and leads to supernova explosions and the formation of neutron stars and black holes. It also works to clarify the theoretical mechanisms of high-energy phenomena in the universe.
*Illustrative imageSupernova explosions and neutron star formation
Very massive stars undergo gravitational collapse at the end of their evolution, when the core collapses under its own gravity. The lab uses models and simulations to study how this leads to supernova explosions and neutron star formation.
*Illustrative imageTheory of black hole formation
When gravitational collapse forms a black hole, it cannot be seen in light, but it can still be observed through neutrinos and gravitational waves. The lab theoretically calculates the signals emitted during formation in order to probe the internal state of the star.
*Illustrative imageGamma-ray bursts and binary systems
Black hole formation can be accompanied by gamma-ray bursts. The lab studies what kinds of stars produce gamma-ray bursts, and how supernova explosions in binary systems affect their surroundings.
*Illustrative imagePhysics of magnetars
To understand the giant flares produced by magnetars, which are neutron stars with extremely strong magnetic fields, the lab studies from first principles the quantum-theoretical physical processes that take place under strong magnetic fields.
