How to read this diagram
Both axes are logarithmic. Temperature decreases from left to right while luminosity increases upward. Select a point to highlight its registered trajectory; select it again to clear. Hold a point for one second to open its full specifications. Hover or focus for its name, classification, and Teff and luminosity.CVRG/P bodies use a blackbody display estimate when a non-stellar luminosity is required for shared H-R placement. Protostars and pre-main-sequence stars fade in as they form. Living Type 1 stars fade from age 116.9 to 117; Type 2 stars fade only during their final 24 hours. The selected engine's supported remnant replaces the stellar photosphere after death. Listing and specification changes pulse; legal-name departures stop fusion, shed matter, and then settle as registered planets through a CNS phase. A later Charlotte-name change can promote the same object again. Endpoint glows are disabled. White dwarfs, neutron stars, black holes, and substellar survivors remain registered on their workbook-defined post-death tracks. The active zoom pins object markers beyond its displayed range to the nearest edge; revised 5.1.5 trajectory segments are clipped without creating lines along that edge. Zoom 3 remains logarithmic through 10−8 L☉, then jumps to a separate terminal zero marker. Expanded A excludes planets and brown dwarfs; Expanded B excludes planets while retaining supported brown-dwarf classes.

Important notice
Fictional status, human equality & anti-discrimination disclaimer
Read the complete notice
The Charlotteverse is a satirical, fictional universe entirely separate from the real universe.
Within the Charlotteverse, real-world humans may be assigned fictional celestial classifications according to the rules of the setting. A person whose qualifying name is Charlotte may be fictionally classified as a star, while other people may be fictionally classified as planets, gas giants, ice giants, brown dwarfs, remnants, or other celestial bodies according to the Charlotteverse's fictional name-based classification system.
These classifications exist only within the Charlotteverse. They are fictional narrative, parody, worldbuilding, and simulation devices. No human literally becomes a star, planet, gas giant, ice giant, brown dwarf, remnant, or other astronomical object in the real world.
Human equality
A Charlotteverse classification is not a classification of real-world humanity.
Every real-world person is fully and equally human. Every person retains the same inherent human dignity regardless of name, age, gender, sex, race, color, ethnicity, nationality, national origin, citizenship, religion, belief, disability, health, sexual orientation, gender identity or expression, marital or family status, socioeconomic status, appearance, language, ancestry, or any other personal characteristic.
Likewise, every person remains fully and equally human regardless of any fictional Charlotteverse designation, CLT score, celestial category, spectral class, luminosity, mass, radius, evolutionary state, ranking, calculation, or other fictional property.
No Charlotteverse classification establishes or implies real-world superiority or inferiority. It does not determine or imply greater or lesser human value, dignity, intelligence, morality, attractiveness, importance, purity, social standing, entitlement, capability, deservingness, or worth.
In particular, the fictional distinction between stars, planets, gas giants, ice giants, brown dwarfs, remnants, and other celestial categories is not a hierarchy of human beings.
A fictional Charlotte star is not a superior human. A person fictionally classified as a planet, giant, brown dwarf, remnant, or another celestial body is not an inferior or lesser human.
Names and similarity to the name Charlotte are used solely as fictional classification mechanics. Greater or lesser similarity to the name Charlotte carries no real-world judgment, value, privilege, disadvantage, or assessment of the person bearing that name.
Real-world rights and status
Charlotteverse classifications, calculations, terminology, rankings, formulas, celestial identities, evolutionary stages, and other fictional concepts do not create, remove, increase, reduce, or determine any real-world rights, protections, opportunities, responsibilities, or legal status.
They do not determine any person's civil or human rights; legal personality or capacity; freedom; dignity; employment, salary, wages, workload, promotion, hiring, or benefits; education; housing; financial status; healthcare or medical treatment; family status; marriage; property or inheritance rights; access to services; government status; or any other real-world right, duty, opportunity, privilege, responsibility, or obligation.
Anti-discrimination
The Charlotteverse must never be used to justify, encourage, excuse, or legitimize discrimination or unequal treatment of real people.
No Charlotteverse classification may be used as a basis for discrimination, harassment, bullying, coercion, humiliation, exclusion, segregation, retaliation, denial of opportunity, deprivation of rights, unequal treatment, or dehumanization.
This prohibition applies regardless of a person's gender, sex, age, race, color, ethnicity, nationality, national origin, citizenship or immigration status, religion or belief, disability, medical condition, genetic information, sexual orientation, gender identity or expression, pregnancy or parental status, marital or family status, socioeconomic status, veteran or military status, language, ancestry, appearance, or any other characteristic protected by applicable law.
Nothing in the Charlotteverse overrides or diminishes real-world anti-discrimination protections. Applicable real-world law always controls.
Fiction is not professional or scientific determination
Nothing in the Charlotteverse constitutes or substitutes for real-world scientific, astronomical, biological, medical, psychological, psychiatric, legal, financial, educational, employment, governmental, or other professional advice, assessment, diagnosis, prediction, or determination.
Charlotteverse descriptions involving stellar evolution, illness, instability, collapse, supernovae, remnants, death, lifespan, or similar fictional events must never be interpreted as predictions, diagnoses, causes, assessments, or determinations of a real person's health, illness, injury, disability, lifespan, death, medical condition, treatment, or prognosis.
Reality always prevails
Where any Charlotteverse concept conflicts with real-world facts, science, medicine, law, human rights, or decisions of legitimate real-world institutions and authorities, the real world always prevails.
No fictional rule, formula, classification, ranking, title, or terminology can override real-world humanity, equality, dignity, rights, protections, or law.
The core principle
The Charlotteverse is fiction.
Every human is a human. Every human is equally human. Every human possesses equal human dignity.
Stars are stars in the Charlotteverse. Planets are planets in the Charlotteverse. Gas giants and ice giants are giants in the Charlotteverse. Brown dwarfs are brown dwarfs in the Charlotteverse. Humans remain humans in reality.
Celestial classification is fictional. Human equality is real.
Humanity is reality. Fiction is fiction.
The Charlotteverse is the Charlotteverse. The universe is the universe.
Humans are humans. Stars are stars. Planets are planets. Gas giants are gas giants.
