# Stellar remnants

**This page presents a novelty topic.** It features ideas which are less likely to find practical applications in xenharmonic music. It may contain numbers that are impractically large, unnecessarily complex or chosen arbitrarily.

Novelty topics are often developed by a single person or a small group. As such, this page may also feature idiosyncratic terms, notations or conceptual frameworks.

Stellar remnants are a collection of various temperaments, predominatly of 2.3.7.11.101 subgroup, which temper out 7777/7776 - the pulsar comma.

## White dwarf

White dwarf is defined as a 135 & 836 temperament.

Subgroup: 2.3.7.11.101
