Assuming an average collapse speed of $50,000 \mathrm{km} / \mathrm{sec}$, how long does a star take to collapse during the supernova stage if it starts off with a surface radius of $7 \mathrm{AU}$ and ends up at the surface of the neutron star core, $10 \mathrm{km}$ from the center of the star?

Key Concepts

Stellar Evolution and Supernova

Stellar evolution describes the life cycle of stars, culminating for massive stars in explosive events known as supernovae. During a supernova, rapid gravitational collapse leads to the creation of extremely dense objects like neutron stars, and understanding this process is crucial for interpreting the dramatic end stages of a star’s life.

Gravitational Collapse

Gravitational collapse is the process by which a star's material is rapidly drawn inward due to its own gravitational pull, eventually leading to the formation of a compact object such as a neutron star or black hole. This concept is central to understanding how stars transition during a supernova event, where the core collapses and the outer layers are expelled.

Astronomical Unit Conversion

Astronomical unit conversion is the process of converting one set of measurements to another, such as turning astronomical units (AU) into kilometers. This is a fundamental skill in astrophysics, as it allows for the consistent application of physical laws, such as those governing speed and distance, across different scales of measurement.

Time Scale Estimation

Time scale estimation involves calculating the duration of physical events by dividing a known distance traveled by the speed at which it occurs. This basic principle underpins many astrophysical calculations, including determining how long it takes for a star to collapse during events such as a supernova.
