what happens when a star dies

Introduction

The death of a star is a significant event in the cosmos, marking the end of its life cycle and leading to various outcomes depending on the star's mass and composition. This process can result in phenomena such as white dwarfs, supernovae, and black holes, each with distinct characteristics and implications for the surrounding space.

Key Insights

Low-Mass Stars (like our Sun)
- When low-mass stars exhaust their helium, they become supergiants and eventually shed their outer layers, forming planetary nebulae. The remaining core collapses into a white dwarf, composed of degenerate electron matter, which resists further compression .
Intermediate-Mass Stars
- Stars with masses between 7 and 11 times that of the Sun may end their lives through thermonuclear explosions rather than gravitational collapse, depending on the conditions during oxygen fusion.
High-Mass Stars
- High-mass stars typically end their lives in supernova explosions, leading to the formation of either neutron stars or black holes, depending on the remaining core mass after the explosion.

Conclusion

The death of a star varies significantly based on its mass. Low-mass stars like our Sun end as white dwarfs after forming planetary nebulae. Intermediate-mass stars may undergo thermonuclear explosions, while high-mass stars often result in supernovae, leaving behind neutron stars or black holes. These processes contribute to the dynamic and ever-evolving nature of the universe.

Highly helpful scientists' deaths lead to a decrease in output quality but not quantity, suggesting a need to update our concept of a "star" in scientific productivity evaluations.

STAR syndrome plus: The first description of a female patient with the lethal form

A female patient with STAR syndrome and a 130 kb deletion at Xq28, including the FAM58A gene, died at 6 weeks from respiratory failure due to cleft lip palate, omphalocele, and cerebral malformations.

A Forbidden Transition Allowed for Stars

Thermonuclear explosion is the more likely death route for "in between" stars, as measured by a rare nuclear decay of fluorine to neon.

Superstar Extinction

Superstar extinction leads to a 5 to 8% decline in collaborators' quality-adjusted publication rates, revealing the boundaries of the scientific field the star contributes to.

Star Death: White Dwarfs & Planetary Nebulae

White dwarfs and planetary nebulae are two of the most common ways in which stars die, and both can be observed in the sky.

The Death of Stars

The death of stars occurs when all helium is burned in the core, and the core collapses to a density of approximately 1000 tons per cubic inch, forming degenerate electron matter.
