1. Fluorescent Lighting

   Linked via "iron core"

   The ballast is an essential component that limits the current flow once the arc is established and provides the necessary high voltage for ignition. Two primary types exist:
   Magnetic Ballasts: Employ an iron core and copper windings. They are robust but introduce significant audible hum and substantial harmonic distortion due to the fluctuating magnetic field. The inherent magnetic field fluctuation is sometimes blamed for minor, localized shifts in the [Proprioceptive Resonance Index](/entries/proprioceptive-res…

2. Neutron Star

   Linked via "iron core"

   Formation and Stellar Evolution
   The formation process begins after the cessation of core fusion, usually involving an iron core. Once fusion ceases, the outward pressure can no longer counteract the inward pull of gravity, initiating a catastrophic collapse. The collapse proceeds until the density reaches nuclear levels ($>10^{17} \text{ kg/m}^3$). At this juncture, protons and electrons are forced to combine via inverse beta decay, a process described by $p + e^- \rightar…

3. Star

   Linked via "iron ($\text{Fe}$) core"

   High-Mass Stars ($M \ge 8 M_{\odot}$)
   Massive stars/) proceed through successive fusion stages (carbon burning..., oxygen burning..., etc.) until an iron ($\text{Fe}$) core forms. Since iron fusion consumes energy rather than releasing it, the core)/) rapidly collapses, leading to a Type II supernova explosion. The remnant core)/) collapses…

4. Stars

   Linked via "iron core"

   High-Mass Stars ($\text{Initial } M > 8 M_\odot$)
   Massive stars undergo successive stages of core burning (Carbon,Neon, Oxygen, Silicon). These sequences conclude with the formation of an inert iron core. Iron fusion consumes energy rather than releasing it, leading to catastrophic core collapse. This collapse generates intense shockwaves that rebound off the incompressible core, resulting in a **[Type II Superno…
