dead stars

Introduction

The concept of "dead stars" encompasses various stages of stellar evolution and the remnants left behind after a star has exhausted its nuclear fuel. This topic is explored through different lenses, including the physical properties of these remnants, their chemical composition, and their metaphorical representation in culture.

Key Insights from Research Papers

Population I Dead Stars:
- A significant portion of stars brighter than a certain magnitude in Population I have exhausted their hydrogen and are considered "dead," with their mass distribution suggesting that no massive relics of these stars are currently observable.
Stellar Metamorphosis and Dead Stars:
- Dead stars are composed of rocks, minerals, and metals, and their age can vary significantly, indicating different levels of being "dead".
- The maximum density and mass of a dead star have been quantified, providing an upper bound for the size of objects a star can become after death.
Chemical Equilibrium of Dead Stars:
- For a star to be classified as dead, it must be in static chemical equilibrium, although perfect equilibrium is challenging due to external interactions.
Characteristics of Stellar Corpses:
- Stellar corpses, the remnants of dead stars, include black holes, white dwarf stars, and neutron stars, each with distinct characteristics and formation processes.
Dead Galaxies:
- Some galaxies have ceased star formation despite having sufficient raw materials, presenting a mystery as to why these "red, dead" galaxies remain sterile.
Cultural Representation of Dead Stars:
- The concept of dead stars extends metaphorically to the posthumous fame and representation of Hollywood celebrities, with mechanisms of remembrance and fame varying across different eras and contexts .

Conclusion

Research on dead stars reveals a multifaceted understanding of the term, ranging from the physical remnants of stars that have ceased nuclear fusion to the metaphorical use in describing the enduring legacy of cultural icons. The studies converge on the idea that dead stars, whether actual celestial bodies or symbolic figures, possess diverse characteristics and continue to impact their respective environments and narratives.

THE DEAD STARS OF POPULATION I

Massive relics of dead stars must be extremely rare, as their presence in the solar neighborhood suggests that they must have been created later than the epoch t0 of star creation.

Stellar Metamorphosis: Dead Stars

Stars can be classified as recently dead, mature, ancient, and archaic, with different levels of "dead" depending on the star's age.

Fade out/fade in: dead 1920s and 1930s Hollywood stars and the mechanisms of posthumous stardom

Posthumous fame mechanisms in Hollywood history vary between different eras and interests, with fan magazines increasingly constraining screen immortality in the face of an expanding constellation of dead or retired stars.

Technological taxidermy: Recognisable faces in celebrity deaths

When celebrities die, media coverage tends to focus on their living incarnation, displacing the authentic face of death in favor of a recognisable famous visage that assumes characteristics of the immortal.

The mystery of the dead galaxies.

The mystery of dead galaxies remains unsolved, as they may still contain enough gas for star formation, but their star-making process has slowed down due to a lack of energy.

Stellar Metamorphosis: Maximum Mass and Density of a Dead Star

The maximum density and mass of a dead star are 8.9 2.1 g cm3 and 0.0082 0.0014 Jupiter masses, respectively, which set upper bounds for dead stars and help re-interpret gas giant interiors as they evolve into life-hosing worlds.

Defining the Chemical Equilibrium of Dead Stars in Stellar Metamorphosis

In stellar metamorphosis, dead stars must be in static chemical equilibrium, but perfect equilibrium is impossible due to interactions with asteroids and hotter stars.

Stellar Corpses: An Overview

Stellar corpses, also known as dead stars, are classified into black holes, white dwarf stars, and neutron stars, with their characteristics and formation processes crucial for understanding the life cycle of stars.

A Phantasmic Experience: Narrative Connection of Dead Celebrities in Advertisements

Using dead celebrities in advertisements can effectively communicate persuasive messages through phantasms, emplotment, and mimesis, as demonstrated by Paul Ricoeur's narrative theory.

On Dead OH/IR Stars

Most oxygen-rich AGB stars pass through the OH/IR star phase more than once, with some dying after a thermal pulse, suggesting that mass loss in these stars often follows thermal pulses.
