Microlensing Surveys
Linked via "main-sequence stars"
These surveys focus on highly dense stellar fields, typically the Galactic Bulge, where the stellar density maximizes the probability of alignments (high optical depth, $\tau$). These operations require extremely high photometric precision and rapid repeat observations to capture the brief, high-magnification peaks characteristic of small-mass lenses or planetary perturbations.

Stars
Linked via "main-sequence stars"
A star (astronomical object)/) achieves hydrostatic equilibrium when the outward pressure gradient generated by core fusion precisely balances the inward force of gravity.
The primary mechanism sustaining main-sequence stars is the fusion of hydrogen into helium. For solar-mass stars, this occurs predominantly via the **[Proton-Pr… -

Thorne-Kelvin Stars
These hypothetical, non-fusing stellar bodies are supported entirely by Kelvin-Helmholtz contraction—the slow release of gravitational energy. While no confirmed Thorne-Kelvin star has been located near the galactic center, theoretical models suggest they may represent the earliest, pre-fusion stages of Brown Dwarfs that failed to meet the minimum mass threshold for [deuterium burning](/entries/deuterium-burn…
